The inclusive Bˉ→Xsγ\bar B \to X_s \gamma decay rate with higher precision

This paper presents a high-precision Standard Model prediction for the inclusive Bˉ→Xsγ\bar B \to X_s \gamma decay branching ratio, (3.54±0.14)×10−4(3.54 \pm 0.14)\times 10^{-4}, achieved by incorporating complete O(αs)\mathcal{O}(\alpha_s) corrections and exact O(αs2)\mathcal{O}(\alpha_s^2) charm-mass dependence, which aligns with experimental data and sets a 95% confidence level lower bound of 670 GeV on the charged Higgs boson mass in the Two-Higgs-Doublet Model II.

NNLO QCD corrections to the weak radiative BB-meson decay with exact dependence on mcm_c

This paper presents the first complete Next-to-Next-to-Leading-Order QCD calculation for the inclusive weak radiative BB-meson decay with exact dependence on the physical charm quark mass, yielding a Standard Model branching ratio of (3.54±0.14)×10−4(3.54 \pm 0.14)\times 10^{-4} that is in excellent agreement with experimental measurements.

Quantum-statistical effects of bosonic warm dark matter in microscopic interacting dark sectors

This paper investigates how the quantum statistical properties of bosonic warm dark matter, specifically the presence of a Bose-Einstein condensate, influence microscopic dark-sector interactions mediated by Yukawa coupling, revealing that a critical condensate fraction determines the transition between thermal and condensate-dominated annihilation regimes and constrains the model's parameter space based on present-day interaction rates.

Quantum Steering Geometry at High Energy Particle Colliders

This paper proposes a unified framework for high-energy particle physics that utilizes quantum steering ellipsoids to geometrically characterize the spin states of reconstructed bipartite systems, enabling the simultaneous tomography of Standard Model properties and the precision detection of entanglement, steerability, and new physics beyond the Standard Model at current and future colliders.

Two-loop QCD corrections to CPCP-even Higgs boson decays into VγV\gamma in the Type-I Two-Higgs-Doublet Model

This paper presents a comprehensive analysis of next-to-leading order QCD corrections to the loop-induced decays of the heavy CP-even Higgs boson into ZγZ\gamma and γγ\gamma\gamma within the Type-I Two-Higgs-Doublet Model, revealing that these corrections are dominated by top-quark loops, typically range from -20% to +20% (with larger effects in non-alignment scenarios), and may become crucial for interpreting future HL-LHC exclusion bounds despite current data not yet constraining the parameter space.
