Investigating forward-backward asymmetry in D-meson production and anisotropic flow in p-Pb collisions at the LHC

Using the heavy-flavor improved AMPT model, this study demonstrates that the forward-backward asymmetry in prompt D0 meson production and elliptic flow in 8.16 TeV p-Pb collisions arises from the interplay of initial-state cold nuclear matter effects and final-state partonic interactions, providing evidence for the formation of a partonic medium in high-multiplicity events.

Quantifying Quantum Correlations in Annihilation Photon Pairs under Compton Scattering

This theoretical study employs the generalized Stokes-Mueller formalism to demonstrate that while polarization entanglement in 511 keV annihilation photon pairs is highly sensitive to Compton scattering geometry and vanishes at right angles, quantum coherence persists even in regimes where entanglement is lost, offering critical insights for quantum-enhanced positron emission tomography.

Evolution of Compact Stellar Systems in Ultralight Dark Matter Halos: Dependence on Stellar and Dark Matter Parameters

This study reveals that the long-term evolution and stability of compact stellar systems in ultralight dark matter halos are significantly influenced by stellar metallicity, the Milky Way's tidal field, and a counterintuitive heating effect that strengthens with increasing particle mass in specific size regimes, suggesting that current constraints on ultralight dark matter derived from these systems may require revision.

Searching for the G(3900)G(3900) via the K−p→Ds−Λc+G(3900)0K^- p \to D_s^- \Lambda_c^+ G(3900)^0 reaction

This paper proposes searching for the G(3900)G(3900) structure via the K−p→Ds−Λc+G(3900)0K^- p \to D_s^- \Lambda_c^+ G(3900)^0 reaction using an effective Lagrangian approach to determine its nature as a genuine resonance or molecular state, free from the interference effects present in e+e−e^+e^- collisions.
