A New Source of Phase Transition Gravitational Waves: Heavy Particle Braking Across Bubble Walls

This paper proposes and rigorously computes a novel mechanism for generating microscopic gravitational waves during cosmological first-order phase transitions, driven by the braking of heavy particles traversing expanding bubble walls, which offers a unique observational signature correlated with particle mass and wall velocity for probing new physics.

Repulsively Bound Hadrons in a Z2\mathbb{Z}_2 Lattice Gauge Theory

This paper demonstrates that resonant pair-production terms in a Z2\mathbb{Z}_2 lattice gauge theory enable the formation of stable, high-energy "repulsively bound" hadrons through a novel dynamical mechanism, a finding supported by matrix product state simulations and an effective model that suggests experimental realization on modern quantum hardware.

The complete three-loop unpolarized and polarized massive operator matrix elements and asymptotic Wilson coefficients

This paper presents the recently completed calculations of three-loop unpolarized and polarized massive operator matrix elements and asymptotic Wilson coefficients for deep-inelastic scattering, while also providing efficient numerical representations of massless coefficients, splitting functions, and target-mass corrections to support QCD fitting.
