Baryon masses with C-periodic boundary conditions

Anian Altherr, Isabel Campos, Roman Gruber +7

Isospin-breaking corrections pose a significant challenge to lattice simulations, both because of the splitting between the up and down quark masses and, in particular, the need to…

Accessing the Gluon Momentum Fraction of Nucleons through the Gradient Flow

Robert Edwards, Joe Karpie, Lorenzo Maio +5

We calculate the gluon momentum fraction of the nucleon using lattice quantum chromodynamics (QCD), with a nonperturbative renormalization technique based on the gradient flow. The…

Deconfinement transitions in three-dimensional compact lattice Abelian Higgs models with multiple-charge scalar fields

Claudio Bonati, Andrea Pelissetto, Ettore Vicari

We investigate the nature of the deconfinement transitions in three-dimensional lattice Abelian Higgs models, in which a complex scalar field of integer charge $Q \geq 2$ is minimall…
