Summary: This work investigates the self-interacting dark matter (SIDM) scenario in the general NMSSM and beyond, proposing an improved analytical expression for the self-interacting cross section of dark matter. By Monte Carlo simulation, the multiplicities and spectra of dark matter/mediator from Higgsino production and decay at the LHC are analyzed.

Summary: Models where the Higgs boson is a composite pseudo-Nambu-Goldstone boson provide attractive solutions to the Higgs mass naturalness problem. By examining three such models based on the minimal SO(5) -> SO(4) symmetry breaking pattern, it is found that each model can satisfy all constraints simultaneously and analysis of the collider phenomenology in viable regions reveals interesting results.

Summary: The SUSY model discusses the introduction of only electrically neutral states, doubling the number of states in the neutralino sector. It presents a rich phenomenology depending on dark matter composition. Collider experiments could test the lower bound on stop and gluino masses, while direct detection experiments will be able to test various dark matter solutions in the future.

Summary: We present our computation of two-loop corrections to the Higgs boson masses of the CP-violating Next-to-Minimal Supersymmetric Standard Model (NMSSM). Our new corrections increase with rising lambda and kappa but remain overall below about 3% compared to our previously computed corrections, in the region compatible with perturbativity below the GUT scale. The impact of CP-violating phases in the new corrections is small, and we show how to efficiently treat the Goldstone Boson Catastrophe due to infrared divergences.

Summary: A recent Fermilab report showed a significant discrepancy between muon g-2 and the standard model prediction. The study suggests that in the general next-to-minimal supersymmetric standard model (GNMSSM), a singlino-dominated neutralino could explain this discrepancy and make the detection of sparticles at the LHC challenging.

Summary: The recent confirmation by Fermilab-based Muon g-2 experiment of the (g - 2)(mu) anomaly has implications for allowed particle spectra in supersymmetry models with dark matter. The study found that general patterns of dark matter could be accommodated in unified SUSY models, unlike in simpler frameworks. Accessing these solutions at the LHC may be challenging due to compressed spectra.

Summary: We study the decay of the lightest Higgs boson h -> MZ in the mu from nu supersymmetric standard model (mu nu SSM), where M is a vector meson (rho, omega, phi, J/Psi, Upsilon). The introduction of three right-handed neutrino superfields in mu nu SSM leads to the mixing of the Higgs doublets with the right-handed sneutrinos, which affects the mass and couplings of the lightest Higgs boson. In certain parameter space, the mu nu SSM can provide significant new physics contributions to the signal strengths of h -> MZ and h -> gamma gamma, which may be observable in high-energy colliders such as a 100TeV collider or other future ones.

Summary: This study investigates the potential for measuring neutrino Yukawa couplings in the NMSSMr model, where the lightest right-handed sneutrino serves as the Dark Matter candidate, and can be produced at next generation e(+)e(-) colliders. The results highlight the purity of the signal from chargino pair production and subsequent decay, providing the opportunity to extract Yukawa parameters in the sneutrino sector.

Summary: The new measurement of the anomalous magnetic moment of muon at the Fermilab Muon g - 2 experiment has highlighted the discrepancy between the standard model prediction and the experimental observation from the BNL measurement. If the new physics responsible for the muon g - 2 anomaly is supersymmetric, obtaining light electroweakinos and sleptons in a systematic way becomes important. The KKLT scenario, with mixed modulus-anomaly mediation, is found capable of explaining the muon g - 2 anomaly in certain parameter regions.

Summary: This study analyzes the appearance of the trilinear squark-Higgs couplings x(q) in the Higgs sector of MSSM and in threshold corrections to the SM, providing constraints on the maximal powers of x(q) in QCD-related loop corrections. It often implies all-order resummations of leading or subleading x(q) contributions in SM-parametrized expressions. Various all-order resummation relations for Delta lambda increment involving x(q)-enhanced terms and different orders in Yukawa and gauge couplings are presented, contrasting elements that cannot be resummed.

Summary: The ThickBrick prescription is used to train machine-learning-based event selectors and categorizers in high energy physics experiments to maximize the statistical significance of signal excess. It eliminates misalignments with physics goals, prevents background distribution from becoming peaked in signal region, and applies optimal selection cutoffs based on event variables. The public Python implementation of ThickBrick includes usage examples for researchers.

Summary: Investigation of a class of neutral naturalness models reveals the Higgs boson as a pseudo-Goldstone boson, with various dimension-six operators obtained by integrating out the radial mode. Chi (2) fit to precision measurements of Higgs couplings suggests a new physics scale could be explored up to 2.3 (2.4) TeV at future colliders, with limits comparable to indirect constraints from electroweak precision measurements.

Summary: Despite being secluded, dark sector particles can interact with photons through feebly interacting with a small mass-dimension charge, dipole moment, or anapole moment and charge radius. If they are light enough, the LHC can produce a concentrated beam of these particles. In this study, the Forward Liquid Argon Experiment (FLArE) is investigated for its potential to search for dark sector particles via electron scattering signatures.

Summary: FASER nu at the CERN Large Hadron Collider is designed to directly detect collider neutrinos and study their cross sections at TeV energies where no such measurements currently exist. In 2018, a pilot detector installed in the far-forward region of ATLAS collected proton-proton collision data at 13 TeV, observing the first neutrino interaction candidates. This milestone opens the door for high-energy neutrino measurements at current and future colliders.

Summary: Researchers investigate the potential for detecting dark matter produced by the LHC in two forward detectors, focusing on nuclear scattering phenomena, and find new parameter space for dark matter masses in the range 5 MeV less than or similar to m(chi) less than or similar to 500 MeV. Combining with previous studies on DM-electron scattering, FASER nu 2 and FLArE have the capability to discover dark matter in a significant portion of the cosmologically favored parameter space with MeV less than or similar to m(chi) less than or similar to GeV.

Summary: This article introduces the numerical software package FORESEE, which can simulate the sensitivity range of experiments in the far-forward direction and provide validated forward spectra for various Standard Model species at different energy levels. The capabilities of FORESEE are demonstrated for dark photon and dark Higgs boson models, as well as the search for light upphilic scalars. Furthermore, the prospects for LLP searches in proposed future hadron colliders are discussed for the first time, including the High-Energy LHC, Super proton-proton Collider, and Future Circular Collider.
