This paper demonstrates that background rotation catalyzes the chiral magnetovortical instability by splitting Alfvén waves into magneto-Coriolis modes, one of which becomes unstable even under weak chiral vortical effects, potentially enabling new dynamo mechanisms in rotating chiral plasmas.
This paper demonstrates that incorporating large- standard U(3) Chiral Perturbation Theory inputs into the on-shell renormalized quark-meson model yields a more robust framework for chiral limit studies, as evidenced by the RQM-S model's stable saturation patterns compared to the divergent behavior observed in the infrared-regularized RQM-I model.
This paper investigates whether a new 17 MeV spin-1 particle with chiral couplings can explain the ATOMKI nuclear anomalies, finding that while the signals can be accommodated, the required parameter space is in tension with constraints from atomic parity violation and direct electron coupling searches.
This paper demonstrates that thermal precondensation, a phenomenon characterized by condensates forming only over finite length scales, occurs in gauge-fermion theories near the thermal chiral phase transition, becomes more pronounced with an increasing number of fermion flavors, and holds potential relevance for physics beyond the Standard Model.
This study presents the first exploratory lattice QCD calculation of nucleon unpolarized, helicity, and transversity parton distribution functions using boosted correlators in the Coulomb gauge, demonstrating that the method yields results compatible with global analyses for valence-quark distributions while highlighting the need to address excited-state contamination in full-quark-channel extractions.
This paper investigates the dark axion portal model by analyzing missing energy signatures in electron fixed-target experiments like NA64e and LDMX, deriving new constraints on dark photon and ALP production mechanisms, and establishing limits on CP-violating couplings using current fermion electric dipole moment measurements.
This paper presents the first complete next-to-next-to-next-to-leading order QCD calculation of heavy-to-light semi-leptonic decay structure functions, enabling precision predictions for triple differential rates that are crucial for determining CKM matrix elements and resolving tensions in measurements.
This paper derives and analyzes higher-order correction terms up to for the invariant mass expressions of multi-particle systems in collider physics, demonstrating that the standard zeroth-order approximations are remarkably robust due to significant cancellations in the correction coefficients.
This paper investigates a -extended Standard Model featuring a scalar-mediated mixed-state dark matter scenario that simultaneously addresses the anomalies, satisfies cosmological and experimental constraints through coannihilation mechanisms, and predicts testable signatures for future direct detection and collider experiments.
Using leading-order chiral perturbation theory, this paper maps the low-energy QCD phase diagram under magnetic fields with baryon and isospin chemical potentials, identifying various exotic phases including a chiral soliton lattice and a hybrid vortex phase that may be relevant to neutron stars at magnetic fields around G.
