摘要

We compute the contribution of order alpha(2)(S)alpha(2) to the cross section of a top-antitop pair in association with at least one heavy Standard Model boson - Z, W-+/-, and Higgs - by including all effects of QCD, QED, and weak origin and by working in the automated MADGRAPH5_AMC@NLO framework. This next-to-leading order contribution is then combined with that of order alpha(3)(S)alpha, and with the two dominant lowest-order ones, alpha(2)(S)alpha and alpha(S)alpha(2), to obtain phenomenological results relevant to a 8, 13, and 100TeV pp collider.

Exact Top-Quark Mass Dependence in Hadronic Higgs Production

M. Czakon, R. Harlander, J. Klappert, M. Niggetiedt

Summary: In this Letter, the impact of the finite top-quark mass on the inclusive Higgs production cross section at higher perturbative orders was calculated at next-to-next-to-leading order QCD. The overall effect was found to be -0.26% at a pp collider energy of 13 TeV, and -0.1% at 8 TeV, eliminating one of the main theoretical uncertainties to inclusive Higgs production cross section at the LHC.

Resummed predictions for hadronic Higgs boson decays

Simone Alioli, Alessandro Broggio, Alessandro Gavardi, Stefan Kallweit, Matthew A. Lim, Riccardo Nagar, Davide Napoletano, Luca Rottoli

Summary: In this paper, the NNLL' resummed 2-jettiness distribution for decays of the Standard Model Higgs boson to a bb-quark pair and to gluons is presented. The calculation relies on a factorisation formula derived using Soft-Collinear Effective Theory, where large logarithms of the 2-jettiness are resummed by renormalisation group evolution. The resummed predictions are matched to the fixed-order NNLO result using the Geneva framework, extending the validity of the results and providing a fully exclusive NNLO event generator matched to the Pythia8 parton shower.

Exploring QED Effects to Diphoton Production at Hadron Colliders

Leandro Cieri, German Sborlini

Summary: This article presents phenomenological studies on the impact of O(alpha) corrections to diphoton production at hadron colliders, with a focus on efficiently computing NLO QED contributions using the Abelianized version of the qT-subtraction method. The analysis reveals percent-level deviations for M-gamma gamma > 1TeV due to experimental selection criteria, underscoring the importance of accurately describing the tail of the invariant mass distribution for new physics searches. Properly handling observable photons by replicating experimental conditions applied to event reconstruction is also emphasized for a better understanding of the phenomena.

Energy-energy correlation in hadronic Higgs decays: analytic results and phenomenology at NLO

Jun Gao, Vladyslav Shtabovenko, Tong-Zhi Yang

Summary: This work completes the investigation of the energy-energy correlation (EEC) function in hadronic Higgs decays at next-to-leading order (NLO) in fixed-order perturbation theory with vanishing light quark masses. The full analytic NLO result for the previously unknown EEC in the H -> q (q) over bar + X channel is given in terms of classical polylogarithms and cross-checked against a numerical calculation. Further corrections to predictions of the Higgs EEC event shape variable, including quark mass corrections, effects of parton shower and hadronization, are discussed. The statistical error on measurements of the Higgs EEC at future Higgs factories is estimated and compared with the current perturbative uncertainty.

The role of colour flows in matrix element computations and Monte Carlo simulations

Stefano Frixione, Bryan R. Webber

Summary: This article discusses how color flows can simplify the computation of matrix elements and enable parton shower Monte Carlos to achieve accuracy beyond leading color. By systematically employing these color flows, tree-level matrix elements and their soft limits can be given in a closed form that does not require any color algebra. Additionally, the study examines how color loops and dipole graphs can help extend the accuracy of Monte Carlos by including subleading-color effects.

Chiral condensates and screening masses of neutral pseudoscalar mesons in thermomagnetic QCD medium

H. -T. Ding, S. -T. Li, J. -H. Liu, X. -D. Wang

Summary: The screening lengths of neutral pseudoscalar mesons are intrinsically connected to (inverse) magnetic catalysis of chiral condensates. The complex dependences of screening masses and chiral condensates on magnetic field and temperature reflect the crossover nature of the QCD transition. These findings are important for guiding low-energy models and effective theories of QCD.

Flavor Identification of Reconstructed Hadronic Jets

Rhorry Gauld, Alexander Huss, Giovanni Stagnitto

Summary: Identifying the flavor of reconstructed hadronic jets is crucial for precision phenomenology and the search for new physics. However, no infrared and collinear safe approach exists for defining the jet flavor using the anti-kT algorithm. We propose a new flavor-dressing algorithm that solves this problem and can be combined with any jet definition. The algorithm is tested in an e+e- environment and applied to the pp & RARR; Z + b -jet process at hadron colliders.

Emotions as computations

Aviv Emanuel, Eran Eldar

Summary: Emotions have a significant impact on our actions, learning, and perception, but there is still ongoing debate about their essence and role. Computational approaches aim to provide a more precise understanding of emotions based on normative principles and neurobiological data. Recent progress suggests that emotions may involve three types of computations, which assess states, actions, and uncertain prospects. By using the framework of reinforcement learning, a new formulation is proposed to better explain existing evidence. Furthermore, integrating extensive research on emotions reveals a simple mapping, where emotions play a vital role in evaluating outcomes, predicting them, informing our actions, and planning for uncertain results.

One-loop electroweak Sudakov logarithms: a revisitation and automation

Davide Pagani, Marco Zaro

Summary: In this work, the algorithm of Denner and Pozzorini for calculating one-loop electroweak Sudakov logarithms is revisited and automated in the MadGraph5_aMC-@NLO framework. By adapting the formulas for modern calculations and extending the algorithm to include NLO EW corrections with QCD corrections, a new approach is proposed where the QED component is consistently removed. The relevance of these innovations is confirmed by numerical results obtained for several processes.

Single top production in association with a WZ pair at the LHC in the SMEFT

Hesham El Faham, Fabio Maltoni, Ken Mimasu, Marco Zaro

Summary: This study focuses on the production of single top quark in association with a WZ pair at the LHC, considering both the Standard Model (SM) and the Standard Model Effective Field Theory (SMEFT). Compared to other electroweak top production processes, tWZ has the advantage of being sensitive to unitarity-violating behavior induced in its 2 -> 2 sub-amplitudes through modified electroweak interactions. The study presents reliable results for total and differential cross sections for tWZ at 13TeV, including the relevant dimension-6 operators.

Local unitarity: cutting raised propagators and localising renormalisation

Zeno Capatti, Valentin Hirschi, Ben Ruijl

Summary: The study addresses two challenges in applying local unitarity representation to higher-loop computations, namely the generalization to graphs with raised propagators and the regularization of ultraviolet and spurious soft singularities. The researchers develop a hybrid (MS) over bar and On-Shell scheme using an all-order construction and a fully automated local renormalization procedure based on Bogoliubov's R-operation. They validate the new technology by calculating (semi-)inclusive results for two multi-leg processes and numerically computing the first physical NNLO cross-sections in momentum-space.

Sensitivity to new physics in final states with multiple gauge and Higgs bosons

A. Cappati, R. Covarelli, P. Torrielli, M. Zaro

Summary: This paper analyses the sensitivity of hadron-collider processes involving the interaction of two electroweak and two Higgs bosons to beyond-the-Standard-Model effects. The experimental results from the CMS collaboration are examined in the context of a dimension-8 extension of the Standard Model. The study shows that constraints from vector-boson fusion Higgs-pair production on modified VVHH interactions are already comparable with or more stringent than those from vector-boson scattering final states. The paper also discusses the potential of new experimental final states and provides an outlook for the high-luminosity phase of the LHC.

Improving methods and predictions at high-energy e+e- colliders within collinear factorisation

V Bertone, M. Cacciari, S. Frixione, G. Stagnitto, M. Zaro, X. Zhao

Summary: This article discusses the use of electron Parton Distribution Functions (PDFs) with next-to-leading collinear logarithmic accuracy in high-energy collision processes. It explores the effects of multiple fermion families and mass thresholds on the evolution of PDFs using the renormalisation group equation, as well as the dependences on factorisation and renormalisation schemes. The impact of uncertainties associated with PDFs on physical cross sections is studied to provide realistic precision estimates for observables computed with collinear-factorisation formulae.

Automated EW corrections with isolated photons: t(t)over-barγ, t(t)over-barγγ and tγj as case studies

Davide Pagani, Hua-Sheng Shao, Ioannis Tsinikos, Marco Zaro

Summary: In this study, the so-called Complete-NLO predictions for top-quark pair hadroproduction in association with at least one isolated photon are computed for the first time. NLO QCD+EW predictions are also calculated for cases with at least two isolated photons and single-top hadroproduction with at least one isolated photon. The results, obtained through an automated approach, extend the capabilities of the MADGRAPH5_AMC@NLO framework and discuss technical details, including a mixed EW renormalisation scheme for such processes.
