Double quarkonium production in hadronic collisions at fixed-target experiments

This paper presents new analytical expressions and predictions for double quarkonium production in unpolarized and polarized hadronic collisions at fixed-target experiments, utilizing transverse momentum dependent factorization combined with the Color-Singlet Model to describe angular structures, cross sections, and transverse single-spin asymmetries for current and future CERN and LHC facilities.

Fierz-complete four-quark interactions and the QCD phase diagram

Using the functional renormalization group approach, this study demonstrates that while scalar-pseudoscalar four-quark channels dominate in the vacuum, other channels become significant near the critical end point, collectively shifting the QCD critical end point to a higher baryon chemical potential and lower temperature while slightly increasing the curvature of the phase boundary.

Single inclusive hadron and jet production in lepton-hadron scattering

This paper presents the first calculation of single inclusive hadron and jet production at large transverse momentum in lepton-hadron scattering using a joint QCD+QED factorization framework, which introduces universal lepton distribution functions with combined evolution kernels and provides predictions for experiments at Jefferson Lab and the future Electron-Ion Collider.

Amplitude of H→γZH \to \gamma Z process via one WW loop in unitary gauge (I. Details of calculation with Dyson scheme)

This paper presents a detailed calculation of the H→γZH \to \gamma Z decay amplitude via a one-WW loop in the unitary gauge, demonstrating how to obtain a finite, gauge-invariant result in four-dimensional Minkowski space without regularization by carefully handling divergent integrals and surface terms while avoiding ambiguous momentum shifts.

Semileptonic Ωb∗→Ωc∗ℓνˉℓΩ_{b}^{*}\rightarrowΩ_{c}^{*} \ell \barν_{\ell} transition in QCD

This paper employs the QCD sum rule method to calculate the form factors and decay widths for the semileptonic weak transition Ωb∗→Ωc∗ℓνˉℓ\Omega_{b}^{*} \rightarrow \Omega_{c}^{*} \ell \bar{\nu}_{\ell}, providing theoretical benchmarks for future experimental studies of excited heavy baryon dynamics.

Perturbative and nonperturbative properties of heavy quark transport in a thermal SU(3) gluon plasma

This paper extends the perturbative framework for heavy quark transport in a thermal SU(3) gluon plasma to the near-critical temperature region by incorporating a temperature-dependent background field, revealing a significant suppression of energy loss and momentum diffusion coefficients due to reduced color charge screening.

Revisiting the limits on dark matter annihilation cross-section and decay lifetime in light of electron and positron fluxes

This paper revises the upper bounds on dark matter annihilation cross-sections and lower bounds on decay lifetimes across a wide mass range by analyzing electron, positron, and gamma-ray fluxes from multiple experiments, finding that AMS-02 and HESS provide the most stringent constraints for masses below and above 2 TeV, respectively, while electron-positron flux data offer the strongest limits for decaying dark matter in the 10310^3–10910^9 GeV range.

Model-independent late-universe measurements of H0H_0 and ΩK\Omega_K with the parametrization based on cosmic age-improved inverse distance ladder

This paper employs cosmic age-based parameterizations (PAge and MAPAge) within an improved inverse distance ladder framework using diverse late-universe datasets to model-independently measure a Hubble constant of 72.20±1.0072.20 \pm 1.00 km s−1^{-1} Mpc−1^{-1}, thereby reducing the H0H_0 tension to the 0.6σ0.6\sigma level and confirming a flat universe consistent with current observational data.

Lesser Green's Function and Chirality-Reduced Entropy via the In-Medium NJL Model

This paper investigates chiral symmetry restoration in hot and dense quark matter using the in-medium Nambu--Jona-Lasinio model by introducing a chirality-reduced von Neumann entropy derived from the lesser Green's function, demonstrating that while this entropy is not an order parameter, its nontrivial behavior across the chiral transition provides a valuable information-theoretic diagnostic of the mixedness in the chirality-reduced subsystem.
