Crossing the phantom divide in scalar-tensor and vector-tensor theories

While shift-symmetric Horndeski and generalized Proca theories struggle to accommodate the phantom-divide crossing suggested by DESI, CMB, and SN Ia data without theoretical pathologies, the authors demonstrate that breaking shift symmetry in Horndeski theories enables a stable model with a scalar potential and Galileon interactions that successfully realizes this transition at low redshifts.

Investigating nuclear effects in lepton-ion DIS at the LHC

This paper investigates the impact of nuclear effects on muon- and neutrino-tungsten deep inelastic scattering events at the LHC's FASERν\nu and FASERν2\nu2 experiments, demonstrating that a simultaneous analysis of inclusive and charm-tagged events can test the universality of nuclear effects and reduce uncertainties in parton distribution functions.

Enhanced Stochastic Gravitational Waves signals from Wess-Zumino chiral superfield

This paper demonstrates that coupling an inflaton to the D-term sectors of chiral superfields, rather than using conventional Yukawa couplings, can enhance the amplitude of stochastic gravitational waves generated during reheating by at least an order of magnitude, thereby highlighting the potential for observing supersymmetric imprints in the gravitational-wave background.

Interpretation of Υ(11020)Υ(11020) as an SS-Wave B1BˉB_1\bar{B}--B1Bˉ∗B_1\bar{B}^* Molecular State

This paper proposes that the Υ(11020)\Upsilon(11020) resonance is an SS-wave B1BˉB_1\bar{B}--B1Bˉ∗B_1\bar{B}^* molecular state and supports this hypothesis by calculating its strong decay widths, which reveal a dominant Bs∗Bˉ∗B_s^*\bar{B}^* channel and distinctive patterns in multi-pion transitions that serve as experimental signatures for heavy-quark symmetry.

Model Study of Eigen-Microstate Signatures of Criticality in Relativistic Heavy-Ion Collisions

This study demonstrates that the eigen-microstate approach (EMA) serves as a robust, background-independent method for identifying critical fluctuations in relativistic heavy-ion collisions by effectively filtering non-critical correlations and capturing the fractal nature of criticality through characteristic eigenvalue patterns and finite-size scaling behaviors.

Inclusive beauty-charmed baryons decay Ξbcq→Ξccq+XΞ_{bcq} \to Ξ_{ccq} +X

Using a non-relativistic potential quark model, this study calculates the inclusive weak decay width of charmed baryons Ξbcq→Ξccq+X\Xi_{bcq} \to \Xi_{ccq} + X to be approximately 4.1×10−134.1 \times 10^{-13} GeV, demonstrating that this process, with a signal significantly exceeding background contributions, offers a viable discovery channel for the doubly heavy baryon Ξbc\Xi_{bc} at the LHC.
