Studies of beauty hadron and non-prompt charm hadron production in pp collisions at $\sqrt{s}$ =13 TeV within a transport model approach

This study employs a refined AMPT transport model with adjusted beauty quark mass and flavor-specific coalescence parameters to successfully reproduce LHCb and ALICE data on beauty and non-prompt charm hadron production in 13 TeV $pp$ collisions, offering new insights into heavy quark dynamics and hadronization mechanisms in small collision systems.

Non-Holomorphic $A_4$ Modular Symmetry in Type-I Seesaw: Implications for Neutrino Masses and Leptogenesis

This paper proposes a minimal Type-I seesaw model governed by non-holomorphic $A_4$ modular symmetry, where neutrino masses and mixings are determined solely by a modulus parameter, successfully accommodating oscillation data and generating the observed baryon asymmetry via thermal leptogenesis while predicting a testable effective Majorana mass for future neutrinoless double-beta decay experiments.

Subleading Effects in Soft-Gluon Emission at One-Loop in Massive QCD

This paper completes the one-loop soft-gluon approximation for massive QCD amplitudes by deriving a new soft operator that preserves on-shell conditions and momentum conservation, while also providing the necessary subleading collinear expansion for massless quark-antiquark pairs.

Freezing-in the Axiverse

This paper employs an effective field theory approach to quantify how multiple light axions contribute to the relativistic degrees of freedom ( $N_{\rm eff}$ ), revealing that their detectability by current and future cosmic microwave background surveys depends sensitively on the flavor structure of their interactions with Standard Model fermions.

Probing Saturon-like Limits in QCD Systems

By applying the BK equation to model gluon occupancy and entropy, this study demonstrates that while protons remain below the unitarity bound, heavy nuclei reach the "saturon" limit at small $x$ , identifying nuclei as the optimal environment for observing this high-occupancy QCD phenomenon.

Precise Predictions for $μ^{\pm}e^-\rightarrowμ^{\pm}e^-$ at the MUonE Experiment

This paper presents state-of-the-art predictions for muon-electron scattering at the MUonE experiment by performing the first all-order resummation of soft and soft-collinear logarithms, matched with higher-order corrections to significantly reduce perturbative uncertainties and accurately describe the signal region.

Azimuthal angular entanglement between decaying particles in ultra-peripheral ion collisions

This paper proposes that ultra-peripheral ion collisions generate entangled multi-particle states through shared photon polarization, leading to distinct azimuthal angular correlations that differ significantly between classical and quantum predictions and offer new avenues for testing multi-particle entanglement.

Rotation catalyzed chiral magnetovortical instability

This paper demonstrates that background rotation catalyzes the chiral magnetovortical instability by splitting Alfvén waves into magneto-Coriolis modes, one of which becomes unstable even under weak chiral vortical effects, potentially enabling new dynamo mechanisms in rotating chiral plasmas.

Improved results of chiral limit study with the large $N_c$ standard U(3) ChPT inputs in the on-shell renormalized quark-meson model

This paper demonstrates that incorporating large- $N_c$ standard U(3) Chiral Perturbation Theory inputs into the on-shell renormalized quark-meson model yields a more robust framework for chiral limit studies, as evidenced by the RQM-S model's stable saturation patterns compared to the divergent behavior observed in the infrared-regularized RQM-I model.

Thermal precondensation in gauge-fermion theories

This paper demonstrates that thermal precondensation, a phenomenon characterized by condensates forming only over finite length scales, occurs in gauge-fermion theories near the thermal chiral phase transition, becomes more pronounced with an increasing number of fermion flavors, and holds potential relevance for physics beyond the Standard Model.
