Search for the lepton flavour violating decay B0→ K*0e±µ∓ with the LHCb detector — •Andreas Güth, Jan-Marc Basels, Christoph Langenbruch, and Stefan Schael — I. Physikalisches Institut B, RWTH Aachen University
The conservation of the individual lepton flavour quantum numbers in interactions involving charged leptons is an important prediction of the Standard Model (SM) of particle physics, making searches for lepton flavour violation (LFV) a promising probe for physics beyond the SM. With its ability for the precise study of the decays of B-mesons, that are copiously produced in proton-proton collisions at the Large Hadron Collider (LHC), the LHCb detector is a powerful tool to search for LFV in b→ sℓ±ℓ′ ∓ transitions. An additional motivation for such searches arises from recent tensions in tests of lepton universality in rare b→ sℓ+ℓ− decays, as lepton non-universality generally implies the existence of lepton flavour violating decays.
In this talk, the status of a search for the LFV decay B0→ K*0e±µ∓ with the LHCb detector is presented, including the analysis strategy, signal selection, and the study of background processes affecting this search.
