The axion-photon coupling from lattice Quantum Chromodynamics
Bastian B. Brandt, Gergely Endrődi, José Javier Hernández Hernández +2
Quantum Chromodynamics (QCD) is the theory of the strong interactions within the Standard Model of particle physics, which explains more than 99% of the mass of the visible Univers…
