New Physics in $b \to s τ^{+} τ^{-}$ Processes and Correlations with $R (D^{()})$ and $B \to K^{()} ν ν ˉ$ : An (SM)EFT Analysis

Guillermo Baltà, Andreas Crivellin, Joaquim Matias +1

Tauonic flavour-changing neutral-current transitions ( $b \to s τ^{+} τ^{-}$ ) are sensitive probes of New Physics connected to third-generation quarks and leptons. Motivated by the persist…

Impact of Hadronic Resonances on $B \to K^{(*)} τ^{+} τ^{-}$ Decays

Guillermo Baltà, Andreas Crivellin, Rafel Escribano +2

Neutral-current semileptonic $B$ decays are plagued by hadronic resonances across the dilepton invariant-mass squared spectrum, $q^{2}$ . For light leptons, $ℓ = e, μ$ , these resonanc…
