On the Relativistic Spatial Localization for massive real scalar Klein-Gordon
quantum particles

Abstract:
I will present some recent achievements about the long-standing issue of
relativistic spatial localization of a quantum (massive scalar) particle. I will
focus in particular on problems related to local causality. A new notion of POVM
localization due to D.Terno will be discussed by pointing out some new
physically meaningful features of it, focussing onthe interplay with the
Newton-Wigner localization, the Hegerfeldt theorem and the causal localization
rquirement introduced by D.P.L. Castrigiano.
