Chiral symmetry restoration effects onto the meson spectrum from a Dyson-Schwinger and Bethe-Salpeter approach

This paper utilizes a Dyson-Schwinger and Bethe-Salpeter approach to demonstrate that the transition from chiral symmetry breaking to restoration in light meson spectra is governed by the location of quark propagator poles relative to the integration domain, offering new insights into the potential emergence of chiral spin symmetry in QCD.

CPCP violation in neutral kaon mixing in D0→KSKSD^0\rightarrow K_SK_S

This paper demonstrates that CP violation in the D0→KSKSD^0 \rightarrow K_S K_S decay induced by neutral kaon mixing is a second-order weak interaction effect estimated at the 10−610^{-6} level, rendering it negligible compared to current experimental sensitivity and expected direct CP violation in the charm sector.

Implications of \textit{SARAS3} data for Coulomb-like interacting dark matter

This paper analyzes SARAS3's non-detection of the 21-cm signal in the 55.5–84.4 MHz band to constrain Coulomb-like interacting dark matter by self-consistently modeling both gas cooling and structure formation suppression, ultimately finding no statistically significant preference for interacting dark matter over standard cold dark matter while establishing a meaningful upper bound on the global 21-cm signal amplitude.

Three-flavor supernova neutrino simulation using a hybrid quantum-classical algorithm with qutrits

This paper presents a hybrid quantum-classical algorithm utilizing qutrits and the Dirac-Frenkel evolution equations to successfully simulate the time evolution of a self-interacting three-flavor neutrino system in a core-collapse supernova, achieving results comparable to exact numerical integration while offering advantages over traditional quantum Trotterization.

Probing Quantum Entanglement in τ+τ−\tau^+\tau^- Pairs via the ππ\pi\pi Channel at STCF

This paper presents a feasibility study demonstrating that the proposed Super Tau-Charm Facility (STCF) can effectively probe quantum entanglement and Bell-inequality violations in τ+τ−\tau^+\tau^- pairs via the ππ\pi\pi decay channel, achieving a reconstructed concurrence of 0.279±0.0070.279 \pm 0.007 through full Monte Carlo simulations at s=7\sqrt{s} = 7 GeV.

Gravitational waves from CP domain wall collapse and electron EDM in a complex singlet model with dimension-five Yukawa interactions

This paper investigates the complementarity between gravitational waves from CP domain wall collapse and electron electric dipole moment measurements in a complex singlet model with dimension-five Yukawa interactions, demonstrating that future EDM experiments can probe parameter regions overlapping with detectable gravitational wave signals to constrain the model's vacuum structure and CP properties.

Multi-Lepton Probes of the Drell-Yan Production of Triplet Higgses

This paper investigates whether a Real Higgs Triplet model (Δ\DeltaSM), proposed to explain a 152 GeV Higgs-like excess in di-photon and ZγZ\gamma spectra, can account for recent LHC triboson excesses via Drell-Yan production, finding that while the model is consistent with current data, it predicts more events than observed and is not statistically preferred over the Standard Model.

Effects of the magnetic field on π0\pi^0 production in ultraperipheral Pb-Pb collisions

This paper investigates the impact of strong magnetic fields on neutral pion production in ultraperipheral Pb-Pb collisions at the LHC, finding that the field-induced reduction in the π0→γγ\pi^0 \to \gamma\gamma decay width leads to a substantial decrease (by a factor of 2–3) in the production cross section.

Probing Saturation Effect in Heavy Meson Pair Correlation in Forward pApA Collisions

This paper investigates heavy meson pair correlations in forward proton-nucleus collisions by incorporating unified Sudakov resummation within the Color Glass Condensate framework, demonstrating good agreement with LHCb data and predicting a robust mass hierarchy in nuclear suppression that highlights the sensitivity of heavy quarks to gluon saturation effects.
