Abstract

We describe the implementation of supersymmetric models in PYTHIA 8 including production and decay of superparticles and allowing for violation of flavour, CP, and R-parity. We also present a framework for importing generic new-physics matrix elements into PYTHIA 8, in a way suitable for use with automated tools. We emphasize that this possibility should not be viewed as the only way to implement new-physics models in PYTHIA 8, but merely as an additional possibility on top of the already existing ones. Finally we address parton showers in exotic colour topologies, in particular ones involving colour-epsilon tensors and colour sextets.

Long-term LHC discovery reach for compressed Supersymmetry models using VBF processes

Nathalia Cardona, Andres Florez, Alfredo Gurrola, Will Johns, Paul Sheldon, Cheng Tao

Summary: The identity of Dark Matter (DM) is a highly discussed topic in particle physics, and Supersymmetry (SUSY) is an important extension of the standard model that can explain the nature of DM. A feasibility study was conducted at the CERN Large Hadron Collider to assess the long-term discovery potential of compressed SUSY models with higgsino-like states. The study found that using vector boson fusion (VBF) processes combined with specific requirements effectively reduces the background and provides new insights into the parameter space of DM models.

Associated production of heavy Higgs bosons with a b(b)over-bar pair in the nonholomorphic MSSM and LHC searches

Utpal Chattopadhyay, AseshKrishna Datta, Samadrita Mukherjee, Abhaya Kumar Swain

Summary: In the NonHolomorphic Supersymmetric Standard Model, the research investigates the relationship between the Yukawa couplings of the bottom quark and the tau lepton and the production cross sections and decay branching ratios of heavy Higgs bosons. The results show that in the NHSSM, the exclusion region in the m(A) - tan beta plane is larger compared to the MSSM, particularly for large tan beta and negative A(b)'. However, the relaxation in m(A) is more limited for large and positive A(b)' due to complementary variations in production cross sections and decay branching fractions.

Mixture-of-Theories training: can we find new physics and anomalies better by mixing physical theories?

Sascha Caron, Roberto Ruiz de Austri, Zhongyi Zhang

Summary: In recent years, model-independent search strategies have become increasingly popular due to the lack of a clear signal in new physics and a parameter-free extension of the standard model. This study proposes a new approach by combining multiple theoretical signal models to improve the search strategy for unknown signals.

The ABC of RPV: classification of R-parity violating signatures at the LHC for small couplings

Herbi K. Dreiner, Yong Sheng Koay, Dominik Koehler, Victor Martin Lozano, Javier Montejo Berlingen, Saurabh Nangia, Nadja Strobbe

Summary: We classify the potential supersymmetric R-parity violating signatures at the LHC and analyze their coverage. We find that all signatures have been covered at the LHC, although not at the desired sensitivity level. For dominant LL E operators, the current lower bounds on supersymmetric masses are comparable to or better than the R-parity conserving case. Our study can be extended to scenarios with multiple non-zero RPV couplings.

Probing compressed higgsinos with forward protons at the LHC

Hang Zhou, Ning Liu

Summary: This paper presents a solution to the challenging problem of probing nearly-degenerate light higgsinos using photon fusion at the Large Hadron Collider. The study demonstrates that this method can achieve good sensitivity and help discover supersymmetric particles in high-energy collisions.

Summary: This study obtains new sets of parameter tunes for two colour reconnection models based on the default CMS PYTHIA 8 underlying-event tune. The new tunes are compared with various measurements at different energies, and are used to estimate the uncertainty related to colour reconnection modelling in the top quark mass measurement.

Flavor- and CP-safe explanation of gμ-2 anomaly

Jason L. Evans, Tsutomu T. Yanagida, Norimi Yokozaki

Summary: Supersymmetry is still a viable explanation for the muon g-2 anomaly, although it exacerbates the SUSY flavor and CP problem for light supersymmetry breaking masses. To address this issue, a flavor-safe gauge mediated explanation of the muon g-2 is proposed, with additional Higgs soft supersymmetry breaking mass parameters. It is shown that this setup provides a generic parameter space within minimal gauge mediation and can dynamically suppress the problematic CP violating phase. Gauge mediation models have large portions of parameter space where the muon g-2 can be explained at 1 sigma level, and the interplay between slepton and CP-odd Higgs masses makes the majority of this model's parameter space testable at the LHC through searches for sleptons or additional Higgs bosons.

Dedicated triggers for displaced jets using timing information from electromagnetic calorimeter at HL-LHC

Biplob Bhattacherjee, Tapasi Ghosh, Rhitaja Sengupta, Prabhat Solanki

Summary: This paper studies the prospect of using ECAL barrel timing to develop triggers for long-lived particles decaying to jets at the level-1 of HL-LHC. The authors construct over 20 timing-based variables and identify two with better performances that are robust against increasing PU. Accurate estimation of QCD prompt jet background rates is achieved using the stitching procedure. The trigger efficiencies can reach up to O(80%) for heavy LLPs with high decay lengths, but decrease for lower masses and decay lengths. The authors also discuss the possibility of including information from displaced L1 tracks to further improve the results, especially for LLPs with lower decay lengths.

TeV-scale leptoquark searches at the LHC and their E6SSM interpretation

Murad Ali, Shaaban Khalil, Stefano Moretti, Shoaib Munir, Roman Nevzorov, Alexandre Nikitenko, Harri Waltari

Summary: We perform a model-independent search for leptoquarks (LQs) at the Large Hadron Collider. Assuming full luminosity of the Run 2, we show that a fully hadronic signal from the tt intermediate state can surpass existing searches relying on leptons in the final state. Our conclusion is supported by a Monte Carlo analysis and we propose the deployment of our search channel in the experimental setting of the Run 3.

Baryon correlations in PYTHIA

Leif Lonnblad, Harsh Shah

Summary: We present the results of our investigation into the angular correlations between baryon pairs in the PYTHIA8 event generator. We examine how color reconnection models and hadronization mechanisms affect these correlations, focusing on the impact of gluons on the baryon production mechanism in the Lund string fragmentation model.

Effect of color reconnection and rope formation on resonance production in p-p collisions in Pythia 8

Ankita Goswami, Ranjit Nayak, Basanta Kumar Nandi, Sadhana Dash

Summary: Resonance production in proton-proton collisions at different energies has been investigated, showing a suppression in the ratio of mesonic resonances with increasing mean number of charged particles and an enhancement in the phi/K and phi/pi ratios for high-multiplicity events. The yield ratios of resonances are found to be independent of collision energy and strongly dependent on event activity, indicating the importance of different color reconnection modes and hadronization processes.

Detecting new physics as novelty - Complementarity matters

Xu-Hui Jiang, Aurelio Juste, Ying-Ying Li, Tao Liu

Summary: This paper introduces an analysis scheme for novelty detection, aiming to improve performance and applicability by utilizing the complementarity between isolation-based and clustering-based novelty evaluators. The scheme is validated using Gaussian samples mimicking collider events, and successfully applied to the detection of two different signals at LHC.

A novel probe of supersymmetry in light of nanohertz gravitational waves

Kai Murai, Wen Yin

Summary: A new era of exploring the early Universe may have begun with the recent strong evidence for the stochastic gravitational wave (GW) background. This article proposes a new potential source of stochastic GWs in the minimal supersymmetric standard model (MSSM) by considering the axion field in the Higgs multiplets. The axion motion triggers the instability of the standard model gauge fields, producing stochastic GWs during inflation. The article also discusses the possibility of the axion within the MSSM driving inflation and the production of primordial magnetic fields.

A novel solution to the gravitino problem

Yu-Cheng Qiu, S. -H. Henry Tye

Summary: In the brane world scenario of string theory, a novel solution to the excessive gravitino production problem in the early universe is proposed. By introducing a non-linear supergravity model with (anti-D3)-branes, different particle physics phenomenologies can be used to solve the problem and simultaneously explain the small observed cosmological constant.

A study of QCD radiation in VBF Higgs production with VINCIA and PYTHIA

Stefan Hoche, Stephen Mrenna, Shay Payne, Christian T. Preuss, Peter Skands

Summary: In this paper, we discuss and illustrate the properties of several parton-shower algorithms available in PYTHIA and VINCIA in the context of Higgs production via vector boson fusion (VBF). We study a set of observables sensitive to the coherent radiation pattern of additional jets and compare different algorithms. Additionally, we investigate the robustness of these predictions as higher-order perturbative matrix elements are incorporated.

Frugal U(1)X models with non-minimal flavor violation for b → sll anomalies and neutrino mixing

Disha Bhatia, Nishita Desai, Amol Dighe

Summary: We analyze a class of models with an extra U(1)(X) gauge symmetry that explain the b -> sll anomalies and generate appropriate quark and neutrino mixing. These models, with specific constraints and parameter space, are consistent with the latest experimental data.

Towards NNLO plus PS matching with sector showers

John M. Campbell, Stefan Hoche, Hai Tao Li, Christian T. Preuss, Peter Skands

Summary: We propose a new technique for fully-differential matching of final-state parton showers to NNLO calculations, focusing on the case of leptonic collisions with two final-state jets. The strategy is enabled by using the antenna formalism for NNLO antenna subtraction and the sector-antenna framework for the shower. Negative weights can be eliminated from the matching scheme as long as the combined real-virtual and double-real corrections do not overcompensate the real-emission term in the three-jet region. We describe the implementation of all necessary components in the VINCIA antenna shower in PyTHIA 8.3.

Axion-like particles as mediators for dark matter: beyond freeze-out

A. Bharucha, F. Brummer, N. Desai, S. Mutzel

Summary: Examined an axion-like particle as a mediator between Standard Model and dark matter, considering constraints from various experiments and cosmology. Found that when the couplings are small, dark matter is generated through decoupled freeze-out. Improved the calculation of relic density using coupled Boltzmann equations.

Summary: Particle physics is at a crossroads, as the completion of the Standard Model and the observation of anomalies beyond the model offer both opportunities and challenges for future research. Systemic deficiencies in experiments and search strategies may hinder the discovery of beyond the Standard Model physics, but new search strategies utilizing CERN open data can help uncover hidden signatures. Access to open data is crucial for fully exploiting the potential of the Large Hadron Collider (LHC).
