Continuous-Spin Particles, On Shell
Brando Bellazzini, Stefano De Angelis, Marcello Romano
We study on-shell scattering amplitudes for continuous-spin particles (CSPs). Poincaré invariance, little-group covariance, analyticity, and on-shell factorisation (unitar…

A novel strategy to prove chiral symmetry breaking in QCD-like theories
Luca Ciambriello, Roberto Contino, Andrea Luzio +2
We demonstrate that chiral symmetry breaking occurs in the confining regime of QCD-like theories with colors and flavors. Our proof is based on a novel strategy, called…
