This paper resolves the -channel singularity problem in scattering involving unstable particles by employing a finite-time formalism that yields analytic results, thereby justifying the treatment of long-lived particles as stable asymptotic states during strong interactions.
This study demonstrates that next-to-leading order BFKL evolution successfully describes the nuclear modification factor for exclusive photoproduction when initialized with a -scaled BGK model, whereas the IP-Sat model fails to reproduce the data, thereby providing a benchmark for investigating non-linear QCD dynamics and gluon saturation.
This paper proposes a Hybrid Quantum Machine Learning framework that integrates parameterized quantum circuits with classical neural networks to significantly enhance the sensitivity of double Higgs boson searches in the channel at the LHC, outperforming both state-of-the-art classical and purely quantum models in constraining production cross-sections and coupling parameters.
This study supports the molecular structure of the resonance as a $DK$ and bound state by successfully describing the branching fractions of decays using experimental data from related -meson reactions and a theoretical framework based on two free parameters.
Using QCD light-cone sum rules, this study calculates the static electromagnetic properties of molecular tetraquark candidates, revealing that their magnetic moments are dominated by light quarks while their near-spherical charge distributions and suppressed charm contributions provide quantitative benchmarks for distinguishing molecular structures from compact multiquark interpretations.
This paper presents a model-independent approach using perturbative methods to derive ready-to-use formulas for studying strong supercooling in first-order phase transitions driven by radiative symmetry breaking, which produce gravitational waves and primordial black holes.
This paper proposes an unification model that dynamically generates fermion masses and solves the strong CP problem through instanton effects, while utilizing non-invertible chiral symmetry breaking and a novel discrete gauge symmetry to absolutely stabilize the proton and link continuous and discrete global symmetries in the infrared.
This paper applies quantum information theory to axion-photon and neutrino systems, demonstrating how their coupled dynamics generate entanglement, characterizing the resulting quantum correlations and speed limits, and establishing connections between axion phenomenology, neutrino oscillations, and fundamental quantum resources.
This paper utilizes effective field theory and a Hubbard-Stratonovich transformation to factorize quarkonium production matrix elements in NRQCD into state-independent gluon correlators and wavefunctions at the origin, thereby verifying existing relationships for S-wave states, identifying new P-wave contributions, and restoring universality to TMD soft transition functions.
This paper investigates how neutrinos emitted by evaporating Primordial Black Holes (PBHs) heat the intergalactic medium via scattering with the Cosmic Neutrino Background, thereby modifying the global 21-cm brightness temperature and providing new constraints on PBH abundance and neutrino self-interaction couplings.
