Benvenuti nell'Anagrafe della Ricerca d'Ateneo
La valutazione delle attività di ricerca che si svolgono nelle università ha assunto un'importanza rilevante sia per l'intero sistema universitario sia all'interno di ogni singolo ateneo. Roma Tre si è quindi dotata di idonei strumenti informativi in grado di supportare al meglio le azioni di monitoraggio e di valutazione delle attività di ricerca svolte nei propri dipartimentied ha realizzato una Anagrafe della Ricerca di Ateneo.
EnglishB-d and B-s meson systems play a fundamental role to test and improve our understanding of Standard Model flavor dynamics. The mixing parameters Delta m(d,s) represent important constraints in the unitarity triangle analysis. Their theoretical estimates require non-perturbative calculations of B-meson decay constants and B-parameters; accurate results, recently obtained from the lattice, axe reviewed. Other phenomenologicay interesting quantities are the beauty hadron lifetime ratios and, the width differences and CP-violation parameters in Bd and B, systems. We discuss their theoretical predictions which, in the last four years, have been improved thanks to accurate lattice calculations and next-to-leading order perturbative computations.

The mixing parameters Delta m(d,s) represent important constraints in the unitarity triangle analysis.

Other phenomenologicay interesting quantities are the beauty hadron lifetime ratios and, the width differences and CP-violation parameters in Bd and B, systems.
