This paper develops a general formalism for computing physical observables in the background field approach by representing propagators as path-ordered exponents, applying it to DIS dijet production to derive a cross section valid in arbitrary kinematics and demonstrating its consistency with known results in both back-to-back and small- limits while providing a quantitative matching between these regimes.
This paper compares explicit symmetry encoding (L-GATr) and implicit structure learning (OmniLearn) in particle physics, finding that both approaches achieve comparable performance across challenging tasks like unfolding and anomaly detection, suggesting that efficiency gains from encoding known physics structures are largely method-independent.
This paper presents a complete analytic calculation of next-to-leading order electroweak corrections to gluon-induced Higgs boson pair production in the high-energy limit, demonstrating that these corrections reduce the cross-section by approximately 10% and providing precise numerical results down to low transverse momenta.
This paper demonstrates that gravitational interactions between dark matter particles and binary systems, particularly double black holes, can significantly boost dark matter velocities to , thereby enabling large noble liquid detectors like LZ and PandaX-4T to achieve competitive sensitivity to sub-GeV dark matter through a model-independent mechanism.
This paper presents a full calculation of Molière scattering between jet partons and QGP quasiparticles implemented within the Hybrid Model, demonstrating that photon-tagged jets serve as a sensitive probe for detecting distinctive experimental signatures of these hard scatterings through their impact on jet substructure observables like the Soft Drop angle and jet girth.
This paper proposes a nonstandard dark matter thermal history where strong self-interactions initially suppress annihilation via dynamic screening, only for a subsequent instability at a critical density to trigger a rapid, far-from-equilibrium annihilation burst that determines the final relic abundance and naturally accommodates both observational constraints and small-scale structure solutions.
This paper proposes that spinning black holes in the Milky Way can act as persistent "scalar sirens" by ejecting light scalar particles via superradiant instability, thereby generating a detectable, high-velocity scalar background that offers a novel, independent probe of isolated black hole populations and scalar field properties.
This paper re-examines the uncertainty of the theoretical prediction for the ground-state hyperfine splitting in muonium and compares it with the assessments found in the two most recent CODATA adjustments of fundamental physical constants.
This paper presents a theoretical computation of the hyperfine splitting for P-wave heavy quarkonium states with next-to-next-to-next-to-next-to-leading-order accuracy and next-to-next-to-next-to-next-to-leading-logarithmic resummation, followed by a phenomenological analysis applied to bottomonium, charmonium, the system, and various leptonic and atomic systems.
This paper proposes that high-energy particle decays function as informationally weak measurements of quantum spin, where decay kinematics serve as continuous pointer variables to reconstruct spin states and unify spin tomography with Aharonov-Vaidman measurement theory.
This paper presents a general method for reconstructing the spin density matrix of multi-particle systems from angular decay data using Bloch parameterization and Wigner-Weyl transforms, and applies it to Monte Carlo simulations of massive particle decays to propose measurements for detecting entanglement and Bell inequality violations.
This paper conjectures analytic expressions for the non-local magic of bipartite pure qudit states with prime local dimensions, supported by numerical evidence for qutrits and ququints, while demonstrating that these expressions fail for composite dimensions and that established qubit relations between non-local magic and entanglement do not generalize to higher-dimensional systems.
This paper validates a modified Teukolsky framework for predicting gravitational-wave ringdown spectra in effective field theories by successfully passing two rigorous null tests and confirming consistency between two independent numerical methods, thereby establishing its reliability for future strong-field tests of General Relativity.
Using the high-quality 100-parsec Gaia DR3 white dwarf sample and advanced population synthesis models, this study derives a stringent upper limit on the axion-electron coupling ( at 95% C.L.), effectively ruling out the previously suggested range of couplings that implied axion-induced cooling.
This paper demonstrates that while nuclear matter containing only nucleons remains stable against inhomogeneous pion condensation despite exhibiting a "moat regime" in pseudoscalar correlations, the inclusion of hyperons at high densities can drive these correlations negative, triggering an instability toward an inhomogeneous pion condensate that significantly alters the neutron star equation of state.
Using the deep-learning algorithm DINGO-lensing to overcome computational limitations, this study reanalyzes the gravitational wave candidate GW231123 with over 200,000 simulations and concludes that it is not a lensed event due to its statistical significance falling below 4, while highlighting the critical impact of waveform systematics and the potential for future discoveries with improved detection statistics.
This paper proposes a predictive Grand Unified Theory in Palatini gravity where a Higgs field drives inflation and breaks symmetry, linking CMB observables and proton decay lifetimes to offer a testable framework that resolves monopole abundance issues and accommodates current cosmological data.
This study utilizes a hybrid hydrodynamic-transport model to simulate Pb+Pb collisions at 2.76 TeV, demonstrating that the coalescence mechanism for deuteron production provides a better description of experimental elliptic flow data than direct thermal production.
This paper introduces an iterative, algorithmic framework that utilizes Dyck paths and Stieltjes-Rogers polynomials to systematically generate all self-energy Feynman diagrams for the single-polaron problem with arbitrary linear coupling, thereby enabling efficient, unbiased diagrammatic Monte Carlo simulations by eliminating stochastic weighting across topologies.
This paper proposes a non-canonical pseudo-scalar extension of the Chern-Simons inflation mechanism that, by reducing the field's sound speed, effectively suppresses sourced scalar perturbations to allow for a dominant, nearly totally polarized chiral gravitational wave background without violating non-Gaussianity constraints.
