This paper analyzes the ratio of structure functions and establishes bounds on top quark pair production at future electron-proton colliders (LHeC and FCC-eh) using collinear factorization and modified Bjorken scaling, while also examining dipole cross-sections and Higgs boson production probabilities in photon-gluon interactions.
This paper proposes using Selenium-82 in scintillating crystals for short-baseline neutrino oscillation searches, highlighting its favorable nuclear properties and presenting a theoretical framework and experimental scheme based on the (3+1) model.
This paper investigates rare kaon decays to constrain the couplings of light vector and axial-vector bosons to non-conserved currents, finding that specific decay modes place stringent limits on these interactions and exacerbate existing tensions regarding the 17 MeV boson hypothesis proposed by the ATOMKI experiment.
This chapter introduces Quantum Chromodynamics at finite temperature and density by presenting the Euclidean path integral formulation, exploring thermal effective field theories, discussing the Equation of State as a key thermodynamic quantity, and concluding with an overview of the phase diagram for strongly interacting matter.
This paper introduces a new algorithm for symbolic syzygy-constrained IBP reduction of Feynman integrals that bypasses large intermediate equation systems to achieve faster processing of high-power numerators, and presents LoopIn, a modular framework for automating multi-loop calculations.
This paper investigates the production of dark matter in association with a Higgs boson via central exclusive photon fusion in 13 TeV proton-proton collisions within the Inert Doublet Model plus a complex Singlet framework, demonstrating how forward proton detectors at the LHC can be used to search for this Beyond the Standard Model process by analyzing the missing mass spectrum for various mass differences.
This paper proposes a scalable, integrated photonics-based experimental approach using refractive index-modulated resonators coupled to single-photon detectors to search for sub-eV dark matter candidates, such as axion-like particles and dark photons, by leveraging nanophotonic confinement to explore previously uncharted parameter space.
This paper analyzes systematic errors arising from higher-twist contamination and kinematic effects in extracting the leading-twist structure function from inclusive DIS on a tensor-polarized deuteron, comparing two target polarization directions to determine that while both options yield comparable errors at Jefferson Lab 12 GeV kinematics, the momentum transfer direction is preferred at higher values.
This paper introduces a new algorithm for the efficient integration-by-parts (IBP) reduction of complex Feynman integrals with high powers of numerators or propagators, utilizing syzygy-constrained symbolic rules and small linear systems to achieve significantly faster computation speeds in demanding applications like multi-loop scattering amplitudes and spinning black hole binary systems.
This paper proposes that cosmological tensions regarding the expansion history and CMB lensing can be resolved by interpreting them as evidence for a negative neutrino mass, which can be realized through new light fields or dark sector models that predict distinct observable signals in polarization and galaxy statistics.
