Reading the footprints of the B-meson flavor anomalies

Claudia Cornella, Darius A. Faroughy, Javier Fuentes-Martin +2

Motivated by the recent LHCb announcement of a $3.1 σ$ violation of lepton-flavor universality in the ratio $R_{K} = Γ (B \to K μ^{+} μ^{-}) /Γ (B \to K e^{+} e^{-})$ , we present an updated, comprehen…

The LFU Ratio $R_{π}$ in the Standard Model and Beyond

Marzia Bordone, Claudia Cornella, Gino Isidori +1

We discuss the possibility of performing precise tests of $μ / e$ universality in $B \to π ℓ^{+} ℓ^{-}$ decays. We show that in wide regions of the dilepton invariant mass spectrum th…

Hunting for $B^{+} \to K^{+} τ^{+} τ^{-}$ imprints on the $B^{+} \to K^{+} μ^{+} μ^{-}$ dimuon spectrum

Claudia Cornella, Gino Isidori, Matthias König +3

We investigate the possibility of indirectly constraining the $B^{+} \to K^{+} τ^{+} τ^{-}$ decay rate using precise data on the $B^{+} \to K^{+} μ^{+} μ^{-}$ dimuon spectrum. To this end, we es…

Hunting for ALPs with Lepton Flavor Violation

Claudia Cornella, Paride Paradisi, Olcyr Sumensari

We examine the low-energy signatures of axion-like particles (ALPs) in lepton flavor violating (LFV) processes. By using a dimension-5 effective Lagrangian, we compute the most gen…

Revisiting the vector leptoquark explanation of the B-physics anomalies

Claudia Cornella, Javier Fuentes-Martin, Gino Isidori

We present a thorough investigation of the vector leptoquark hypothesis for a combined explanation of the $B$ -physics anomalies. We analyze this hypothesis from a twofold perspecti…

Low-energy signatures of the $PS^{3}$ model: from $B$ -physics anomalies to LFV

Marzia Bordone, Claudia Cornella, Javier Fuentes-Martin +1

The three-site Pati-Salam gauge model provides a consistent description for the hints of lepton-flavor non-universality observed in $B$ decays, connecting the present pattern of "a…
