Non-derivative Axionic Couplings to Nucleons at large and small N
Francesco Bigazzi, Aldo L. Cotrone, Matti Järvinen +1
Among the possible CP-odd couplings of the axion to ordinary matter, the most relevant ones for phenomenology are the Yukawa couplings to nucleons. We analyze such non-derivative c…

The Holographic QCD Axion
Francesco Bigazzi, Alessio Caddeo, Aldo L. Cotrone +2
A holographic model of QCD axion is presented. It describes a composite axion in the KSVZ class. Having a gravity dual, based on the Witten-Sakai-Sugimoto model, it is calculable i…
