Fully charm tetraquark production at hadronic collisions with gluon radiation effects

This paper presents the first complete next-to-leading order QCD calculation for fully charm tetraquark production at hadronic collisions, incorporating gluon radiation effects through resummation and utilizing LHCb and CMS data to extract universal long-distance matrix elements and predict kinematic distributions for the X(6900)X(6900) and its spin-zero partners.

NLO QCD sum rules analysis of 1+1^{-+} tetraquark states

This paper employs next-to-leading order QCD sum rules to analyze 1+1^{-+} light tetraquark states, concluding that the π1(1400)\pi_1(1400) is unlikely to be a tetraquark while identifying the π1(2015)\pi_1(2015) as a strong tetraquark candidate around 2.0 GeV and suggesting the π1(1600)\pi_1(1600) is less likely to be a tetraquark than previously thought.

Bayesian Constraints on the Neutron Star Equation of State with a Smooth Hadron-Quark Crossover

This paper employs Bayesian inference within a unified framework to constrain the neutron star equation of state across hadronic, crossover, and quark phases, revealing that current multi-messenger data strongly limit low-to-intermediate density nuclear symmetry energy parameters while leaving high-density quark matter properties largely unconstrained until next-generation observations become available.

Hidden-charm udsccˉuds\,c\bar c pentaquarks as flavor eigenstates in a constituent quark model

Using a diffusion Monte Carlo algorithm within a constituent quark model, this study demonstrates that explaining the observed Pcs(4338)P_{cs}(4338) and Pcs(4459)P_{cs}(4459) pentaquarks requires the total wavefunction to be an eigenvector of the SU(3) flavor operator, a condition that yields two mass-compatible structures and predicts additional states below the J/ψΛJ/\psi\Lambda threshold, whereas imposing only isospin symmetry results in a single structure.

Self-Interaction and Galactic Magnetic Field Bounds on Millicharged Magnetic Monopole Dark Matter

This paper investigates a dark matter model consisting of millicharged magnetic monopoles from a dark U(1) sector with kinetic mixing to the Standard Model, deriving constraints on its parameters from dark matter self-interactions and the survival of galactic magnetic fields via the Parker effect across three distinct phenomenological scenarios.
