A new look at $b \to s$ observables in 331 models

Francesco Loparco

Flavour changing neutral current (FCNC) processes are described by loop diagrams in the Standard Model (SM), while in 331 models, based on the gauge group $\text{SU}(3)_C \times \t…

Flavour anomalies, correlations, hadronic uncertainties, and all that

Pietro Colangelo, Fulvia De Fazio, Francesco Loparco +1

We present a short overview of the so-called flavour anomalies, discussing their significance and the connections with QCD issues discussed at the HADRON 2023 conference.

New Physics couplings from angular coefficient functions of $B ˉ \to D^{*} (D π) ℓ ν ˉ_{ℓ}$

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 $B ˉ \to D^{*} (D π) ℓ ν ˉ_{ℓ}$ , with $ℓ = e, μ$ ,…

Dalitz decays $D_{s J}^{()} \to D_{s}^{()} ℓ^{+} ℓ^{-}$

Pietro Colangelo, Fulvia De Fazio, Francesco Loparco +1

The Dalitz decays of the positive parity $D_{s J}^{(*)}$ charmed mesons, $D_{s J}^{(*)} \to D_{s}^{(*)} ℓ^{+} ℓ^{-}$ with $J = 0, 1, 2$ and $ℓ = e, μ$ , are important processes to invest…

Semileptonic $B_{c}$ decays to $P -$ wave charmonium and the nature of $χ_{c 1} (3872)$

P. Colangelo, F. De Fazio, N. Losacco +2

The hadronic form factors of $B_{c}$ semileptonic decays to the $P -$ wave charmonium 4-plet can be expressed near the zero-recoil point in terms of universal functions, performing a s…
