Poincaré group, CPT and flavor states

Giorno 30 ottobre 2019, con inizio alle ore 15:30, presso l'Aula F del DFA, su invito del Dr Dario Zappalà (INFN-CT), il Dr Luca Smaldone (Dipartimento di Fisica, Università di Salerno) terrà un seminario dal titolo Poincaré group, CPT and flavor states.

Tutti gli interessati sono invitati a partecipare.

Abstract. We study the explicit form of Poincaré and discrete transformations of flavor states in a two-flavor scalar model presenting field mixing. We find that, because of its condensate structure, both Poincaré and CPT symmetries are spontaneously broken on flavor vacuum. Its symmetry is just the Euclidean symmetry for each flavor, E(3)AE(3)B. By extending the Fabri-Picasso theorem we show that flavor vacua corresponding to a different time and to different Lorentz frames are unitarily inequivalent, and that they form a flavor vacuum manifold of equal-charged states.
