Impact of Hadronic Resonances on $B \to K^{(*)} I ¨ ^{+} I ¨ ^{-}$ decays

Guillermo BaltÃ, 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, $ℓ = e, I^¼$ , these resonan…

Dark light shining on $B \to K^{(*)} E_{miss}$

Patrick D. Bolton, Jernej F. Kamenik, MartÃn Novoa-Brunet

Recent Belle II data on $B^{+} \to K^{+} E_{miss}$ show an excess consistent with a two-body decay involving a light invisible particle with mass around $2.1 GeV$ . We pre…

Impact of new invisible particles on $B \to K^{(*)} E_{miss}$ observables

Patrick D. Bolton, Svjetlana Fajfer, Jernej F. Kamenik +1

Motivated by a recent Belle~II measurement that suggests an excess in the rare decay $B \to K E_{miss}$ , and building upon our recent differential decay rate likelihood analy…

Model-independent unbinned analysis of $B \to K^{*} (\to K^{+} I ¨ ^{-}) I^¼^{+} I^¼^{-}$ : zeroes, bounds, Wilson coefficients and symmetries

Bernat Capdevila, Joaquim Matias, MartÃn Novoa-Brunet +2

We present a model-independent method to study the four-body decay $B \to K^{*} (\to K^{+} I ¨ ^{-}) I^¼^{+} I^¼^{-}$ , based on extracting continuous observables with a moments approach. The method a…

Signatures of Light New Particles in $B \to K^{(*)} E_{miss}$

Patrick D. Bolton, Svjetlana Fajfer, Jernej F. Kamenik +1

The recent Belle II observation of $B \to K E_{miss}$ challenges theoretical interpretations in terms of Standard Model neutrino final states. Instead, we consider new physics…
