The twist-3 gluon contribution to ANA_N in J/ψJ/\psi production in $pp$ collisions

This paper presents the first rigorous collinear factorization calculation of the twist-3 gluon contribution to the single transverse-spin asymmetry in J/ψJ/\psi production, demonstrating that the CC-even gluon distribution drives a sizable asymmetry at RHIC and LHC energies and offering a unique probe for the three-dimensional motion of gluons within the proton.

A comparative study of TccT_{cc} versus X(3872)X(3872) production in $pp$ collisions at s=\sqrt{s}= 7 TeV

This paper utilizes the PACIAE and DCPC models to compare TccT_{cc} and X(3872)X(3872) production in 7 TeV $pp$ collisions, revealing significant differences in transverse momentum spectra between compact tetraquark and molecular states that can serve as experimental criteria for distinguishing their internal structures.

Redetermination of proton sea distributions

This paper presents a redetermination of the proton's light flavor sea quark distributions using NNLO global analyses of HERA and ATLAS data, revealing an unexpected asymmetry where the anti-up quark distribution exceeds the anti-down quark distribution in the momentum fraction range x(102,1)x\in(10^{-2}, 1), leading to a Gottfried Sum Rule value that significantly differs from previous experimental results.

Probing the Rare Four-Bottom Higgs Decay HbbˉbbˉH\to b\bar b b\bar b at the HL-LHC and ILC

This paper proposes the rare Standard Model Higgs decay HbbˉbbˉH\to b\bar b b\bar b as a probe of Higgs interactions, calculating its branching ratio of approximately 1.6×1031.6\times10^{-3} and demonstrating that it can be observed with high significance at both the High-Luminosity LHC and the ILC using multivariate analysis techniques.

Lee-Yang zeros and edge singularity in a mean-field approach

This paper investigates the analytic structure of the partition function in a finite-volume mean-field QCD model to analyze the temperature dependence of Lee-Yang zeros and edge singularities, demonstrating that while finite-size scaling methods can successfully locate the critical point, accurate determination requires a careful treatment of corrections from irrelevant operators.
