This paper presents a unified framework for simulating exclusive boson production in electron-proton collisions at the future Electron-Ion Collider, which integrates phenomenological amplitudes for various particles to provide precise kinematic predictions that surpass traditional flux-factorized approximations, particularly for multi-differential observables and forward-proton acceptance studies.
This paper demonstrates that a future 10 TeV muon collider can significantly surpass current and projected LHC and FCC-ee limits by using detailed simulations of Higgs and top quark production processes to constrain dimension-6 SMEFT operators and probe new physics scales far beyond the LHC's reach.
This paper refutes claims that quantum damping of cosmological shear in modified loop quantum cosmology is non-generic by demonstrating that previous counterexamples relied on unphysical initial conditions, and establishes that for physically admissible three-dimensional contracting universes, shear damping is a robust feature leading to an isotropic attractor and classicalization.
Using the complete Borexino dataset from 2007 to 2021, researchers established the most stringent experimental limits to date on the lifetime of nuclei against Pauli exclusion principle-forbidden transitions, setting lower bounds ranging from to years for various decay channels and deriving extremely tight upper limits on the relative strengths of such non-Paulian processes.
This paper outlines a modern, transparent, and methodologically robust effort to improve the precision and reliability of nuclear charge radii determinations by integrating complementary experimental techniques with advanced theoretical frameworks.
This paper presents a numerical program that calculates deep inelastic scattering structure functions at next-to-leading order accuracy within the dipole picture, utilizing a reformulated expression for massive quark impact factors to ensure stable cross-section evaluations.
This paper investigates the solar production of symmetrons via photon conversion in the tachocline and their subsequent absorption in underground liquid xenon detectors, establishing new astrophysical bounds based on solar luminosity limits and deriving complementary direct-detection constraints using XENONnT data to probe previously uncharted regions of symmetron parameter space.
This paper presents a general prescription for spurion analysis that systematically tracks coupling constants in particle scattering processes governed by commutative non-invertible fusion algebras, unifying previous approaches and supporting the view that such non-invertible selection rules can be described by lifted Abelian groups with explicit breaking terms.
This paper investigates the production of light dark radiation particles (such as dark Higgs scalars, dark photons, right-handed neutrinos, and axion-like particles) via gravity-mediated interactions in the early universe, deriving constraints on the reheating temperature and equation of state from Planck 2018 CMB data and identifying future experimental prospects for probing these scenarios.
This study utilizes galaxy cluster number counts from the SRG/eROSITA all-sky survey, combined with weak lensing data, to establish the first constraints on the relic density of ultralight axion dark matter across a broad mass range, identifying tight exclusion limits in the intermediate mass regime that are further strengthened when combined with cosmic microwave background observations.
