Hunting for new physics in $B$ meson $b \to u$ transitions: A fresh look with Belle II data

Pietro Colangelo, Fulvia De Fazio, Maria Letizia Di Cuia +1

We present an analysis of the decays $B^{-} \to ℓ^{-} ν ˉ_{ℓ}$ , $B ˉ^{0} \to π^{+} ℓ^{-} ν ˉ_{ℓ}$ , and $B^{-} \to ρ^{0} ℓ^{-} ν ˉ_{ℓ}$ leveraging the precise measurem…

Semileptonic $B_{q}$ decays to heavy tensor mesons

Pietro Colangelo, Fulvia De Fazio, Carlo la Torre +1

The semileptonic decays of $B_{q}$ mesons ( $q = u, d, s$ ) to $J^{P} = 2^{+}$ charmed mesons are investigated. The form factors parametrising the hadronic matrix elements of the weak vector and…

Constraining $ν$ SMEFT coefficients: the case of the extra $U (1)^{'}$

Pietro Colangelo, Fulvia De Fazio, Francesco Loparco +1

We study the constraints on low-energy coefficients of the $ν$ SMEFT generalization of the Standard Model effective theory in the simple case of a $U (1)^{'}$ enlargement o…

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 $ℓ = e, μ$ ,…

Novelties from Flavour Physics

Fulvia De Fazio

Our present understanding of elementary particle interactions is the synergic result of developments of theoretical ideas and of experimental advances that lead to the theory known…
