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…

The Ward identity of Symmetry Breaking from Holographic Renormalization
Andrea Marzolla
Notes on holographic renormalization as a tool for UV analysis and derivation of the two-point Ward identity encoding symmetry breaking. Goldstone theorem is reviewed, discussing i…

The four-dimensional on-shell three-point amplitude in spinor-helicity formalism and BCFW recursion relations
Andrea Marzolla
Lecture notes on Poincaré-invariant scattering amplitudes and tree-level recursion relations in spinor-helicity formalism. We illustrate the non-perturbative constraints imposed ov…
