Two-lepton tales: Dalitz decays of heavy quarkonia

Pietro Colangelo, Fulvia De Fazio, Riccardo Pinto

We study the Dalitz decays of heavy quarkonia, which result from the internal virtual photon conversion into an $ℓ^{+} ℓ^{-}$ lepton pair. Heavy-quark symmetries allow us to esta…

Correlating lepton flavour violating $b \to s$ and leptonic decay modes in a minimal abelian extension of the Standard Model

Pietro Colangelo, Fulvia De Fazio, Davide Milillo

We consider an abelian extension of the Standard Model (SM) comprising a new gauge group $U (1)^{'}$ , with the neutral gauge boson $Z^{'}$ having flavour violating couplings t…

The charming case of $X (3872)$ and $χ_{c 1} (2 P)$

Pietro Colangelo, Fulvia De Fazio, Giuseppe Roselli

More than twenty years have elapsed since the discovery of $χ_{c 1} (3872)$ (previously denoted as $X (3872)$ ), and an impressive amount of theoretical and experimental studies has be…
