This paper presents a comprehensive formalism and phenomenological analysis for calculating exclusive dijet production in electron-proton collisions using collinear QCD factorization and Generalized Parton Distributions, highlighting distinct kinematic behaviors of valence quark contributions at high that are inaccessible at HERA but promising for future Electron Ion Collider measurements.
This paper extracts the speed of sound in the quark-gluon plasma from ATLAS transverse momentum fluctuation data in ultra-central Pb+Pb collisions by correcting for detection biases and hadronization noise, yielding a result of that aligns perfectly with first-principles lattice QCD calculations.
This paper presents a self-contained next-to-next-to-leading-order (NNLO) perturbative QCD calculation of dimuon production in neutrino-nucleus deep-inelastic scattering based on the semi-inclusive DIS framework, demonstrating that these corrections significantly reduce scale uncertainties at large momentum fractions and alleviate the tension between dimuon and LHC data at small momentum fractions by introducing negative corrections.
This study utilizes Langevin dynamics within an extended quasiparticle model to demonstrate that while electrical conductivity significantly influences the splitting of directed flow () between D and B mesons via electromagnetic fields at LHC energies, chiral conductivity plays a marginal role, ultimately revealing opposite signs for charm and bottom mesons with the latter exhibiting smaller magnitudes.
This paper utilizes a three-quark light-front model to calculate the gluon Sivers function of a proton at moderately small and numerically determines its small- evolution via the BFKL anomalous dimension, revealing a power-law tail behavior of at high transverse momentum.
This paper synthesizes new threshold measurements of production from JLab experiments (007 and CLAS12) with previous GlueX data to confirm a consistent phenomenological determination of the -proton scattering length, while highlighting how upcoming J-PARC measurements will further clarify the systematic trend of vector meson-nucleon interactions predicted by the "young vector meson" hypothesis.
This paper proposes a novel method to constrain feebly-interacting particles by analyzing the heating and ionization of circumstellar medium around core-collapse supernovae, using non-detections of precursor emission from SN 2023ixf to establish stringent new limits on MeV-scale dark photons.
This paper demonstrates that a joint Bayesian calibration of low- bulk observables and high- tomographic data significantly tightens constraints on Quark-Gluon Plasma properties and resolves discrepancies in high- anisotropy predictions that arise when using low- data alone.
This paper proposes a viable TeV-scale vector-like dark matter candidate within an extended left-right symmetric model featuring an additional gauge symmetry, demonstrating its consistency with relic abundance, collider limits, and current direct and indirect detection constraints while highlighting the complementary roles of future multi-ton detectors and the CTA telescope in probing the model's parameter space.
This paper presents an overview of the McMule Monte Carlo framework and its recent extensions to include low-energy electroweak effects and non-perturbative hadronic contributions via disperon QED, highlighting their applications to precision experiments like MOLLER and the technical challenges of consistent effective field theory matching.
Using a unified chiral effective field theory framework calibrated with lattice QCD data, this study predicts repulsive interactions for the system while identifying strong attractive forces in the system that support bound states, with significant mass splitting between channels driven by two-pion exchange spin-spin terms.
This paper utilizes functional QCD to determine QCD freeze-out conditions by matching theoretical baryon number susceptibilities with experimental proton cumulants, successfully predicting kurtosis values that agree with data and revealing a peak structure near 5 GeV indicative of a critical end point.
This paper presents a theoretical framework and experimental feasibility study demonstrating that muonic kaon atoms can be produced via decays and quark-gluon plasma coalescence at high-energy colliders, offering a novel probe for low-momentum primordial muons and early-time electromagnetic radiation with projected yields sufficient for their first observation.
This paper reviews the theoretical advantages and experimental progress in studying exotic hadrons associated with the -quark, highlighting the unique capabilities of the Belle, Belle II, and LHCb experiments to explore states like , , and within a more reliable theoretical framework than charmonium-like systems.
This paper evaluates the robustness of collider constraints on the type-II seesaw mechanism by analyzing how motivated extensions of the model alter the production and decay phenomenology of exotic Higgs bosons, thereby potentially modifying standard sensitivity expectations.
This paper investigates potential new physics effects in the semileptonic decays by calculating hadronic form factors within a covariant quark model, constraining Wilson coefficients of four-fermion operators using recent experimental data, and providing theoretical predictions for observables to guide future tests.
This paper explores a classically conformal gauge theory with a triplet dark scalar, identifying three distinct dark matter scenarios—WIMP, supercooled DM, and monopole—that arise from the model's unique first-order phase transition history and analyzing their viability against current constraints and future experimental sensitivities.
This paper systematically investigates the scalar sector contributions to the electroweak oblique parameters , , and within the 3-3-1 model with right-handed neutrinos, demonstrating that the parameter imposes stringent constraints on the model's scalar masses and energy scales.
This paper proposes a Flavored Peccei-Quinn model that unifies the explanation of quark flavor textures, the strong CP problem, and neutrino masses via a type-I seesaw mechanism, while predicting phenomenological signatures such as intermediate scalar resonances and specific axion-photon couplings constrained by current experimental data.
This paper investigates axion-neutrino interactions within Type-I and inverse seesaw models, finding that while the effective coupling is constrained by astrophysical limits on axion-electron couplings, the resulting optical depths for axion-mediated neutrino scattering are too small to produce observable signatures with current sensitivities.
