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

Pietro Colangelo, Fulvia De Fazio, Giuseppe Roselli

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

Temperature and chemical potential dependence of the gluon condensate: a holographic study

Pietro Colangelo, Floriana Giannuzzi, Stefano Nicotri +1

The lowest dimensional gluon condensate $G_{2}$ is analyzed at finite temperature and chemical potential using a holographic model of QCD with conformal invariance broken by a backgr…

Rare semileptonic $B \to K^{*} ℓ^{+} ℓ^{-}$ decays in RS $_{c}$ model

Pietro Biancofiore, Pietro Colangelo, Fulvia De Fazio

Recent LHCb measurements show small discrepancies with respect to the Standard Model (SM) predictions in selected angular distributions of the mode $B^{0} \to K^{* 0} I^¼^{+} I^¼^{-}$ . The…

New Physics couplings from angular coefficient functions of $B ˉ \to D^{*} (D I ¨ ) ℓ I^ˉ ½_{ℓ}$

Pietro Colangelo, Fulvia De Fazio, Francesco Loparco +1

The Belle Collaboration has recently measured the complete set of angular coefficient functions for the exclusive decays $B ˉ \to D^{*} (D I ¨ ) ℓ I^ˉ ½_{ℓ}$ , with $\ell=e,\,Î…

Exotic $J^{P C} = 1^{-+}$ mesons in a holographic model of QCD

Loredana Bellantuono, Pietro Colangelo, Floriana Giannuzzi

Mesons with quantum numbers $J^{P C} = 1^{-+}$ cannot be represented as simple quark-antiquark pairs. We explore hybrid configurations in the light meson sector comprising a quark, an…

Nonleptonic $B_{s}$ to charmonium decays: analyses in pursuit of determining the weak phase $I^_{s}^{2}$

Pietro Colangelo, Fulvia De Fazio, Wei Wang

We analyze nonleptonic $B_{s}$ decays to a charmonium state and a light meson, induced by the $b \to c c ˉ s$ transition, which are useful to access the $B_{s}$ - $B ˉ_{s}$ mixing…
