The $Z_3$ soft breaking in the I(2+1)HDM and its cosmological probes

This paper investigates the phenomenological and cosmological implications of introducing a $Z_3$ soft-breaking term in the I(2+1)HDM, analyzing scenarios where the resulting long-lived neutral scalar serves as a dark matter candidate or produces distinctive displaced vertex signatures at the International Linear Collider.

Standard Model W, Z (+jet) at CMS and ATLAS

This paper reviews recent precision measurements of Standard Model W and Z boson production (including Z+jet and boosted W decays) by the ATLAS and CMS collaborations using Run 2 data, highlighting their role in rigorously testing perturbative QCD, electroweak theory, and parton distribution functions.

Probing CP Violation with Hyperon EDMs at BESIII

This review synthesizes recent advancements in searching for hyperon electric dipole moments as probes of CP violation beyond the Standard Model, highlighting the BESIII experiment's novel modular angular analysis of entangled baryon-antibaryon pairs from $J/\psi$ decays, which established a three-order-of-magnitude improved upper limit on the $\Lambda$ EDM.

Energy Correlators Within Jets in Transversely Polarized Proton-Proton Collisions at $\sqrt{s} = 200$ GeV

The STAR collaboration at RHIC reports the first measurement of one- and two-point energy correlators within jets in transversely polarized proton-proton collisions at $\sqrt{s}=200$ GeV, observing significant spin-dependent asymmetries that provide a novel, precise probe of nucleon transversity and nonperturbative dynamics for future three-dimensional nucleon tomography.

sPHENIX measurement of Open-Charm Baryon-to-Meson Ratios in $p$+$p$ collisions at RHIC

This paper presents the first measurement of open-charm baryon-to-meson ratios, specifically the $\Lambda_c^+ / D^0$ baseline, in $p$+$p$ collisions at RHIC energies using the high-statistics, unbiased dataset collected by the sPHENIX experiment to investigate heavy-flavor hadronization mechanisms.

Theoretical modeling of charged current $\nu_\mu(\bar\nu_\mu)-^{40}Ar$ DIS at DUNE energies

This paper presents a theoretical study of charged current $\nu_\mu(\bar{\nu}_\mu)$-induced deep inelastic scattering on $^{40}\mathrm{Ar}$ at DUNE-relevant energies, utilizing a microscopic framework with nuclear medium effects and NNLO QCD corrections to compute nuclear structure functions and differential cross sections.

Federated Learning with Quantum Enhanced LSTM for Applications in High Energy Physics

Comprehensive analyses of rare $\Lambda_b \rightarrow \Lambda \ell^+ \ell^-$, $\Sigma_b \rightarrow \Sigma \ell^+ \ell^-$ and $\Xi_b \rightarrow \Xi \ell^+ \ell^-$ decays in 2HDM

This paper investigates rare dileptonic decays of $\Lambda_b$, $\Sigma_b$, and $\Xi_b$ baryons within the Type III Two-Higgs-Doublet Model, calculating key observables like branching ratios and forward-backward asymmetries using light-cone QCD form factors to compare predictions against Standard Model results and assess the model's viability for future experimental verification at LHCb and Belle II.

Isospin-symmetry violation -- kaons and beyond (ISO-BREAK 25: summary and outlook)

This paper summarizes the ISO-BREAK 25 workshop held in Kielce in October 2025, which reviewed the current status of isospin-symmetry breaking observed by NA61/SHINE in nucleus-nucleus collisions, discussed its confirmation by other experiments, and outlined future experimental and theoretical priorities to explain this phenomenon.

Unraveling the Hyperon Puzzle in Neutron Stars via Novel, High-Precision Hyperon Factories

This paper proposes a novel high-luminosity experimental approach using tagged hyperons produced in proton-proton collisions within a nested-target setup to precisely measure hyperon-nucleon interactions, thereby addressing the uncertainties in the equation of state that underlie the hyperon puzzle in neutron stars.
