Search for the lepton flavour violating decays B+ → K+ e±µ∓ with the full dataset of the LHCb experiment — Johannes Albrecht, •Alexander Battig, and Elena Dall’Occo — Technische Universität Dortmund
The conservation of lepton flavour in interactions of charged leptons is an important prediction of the Standard Model of particle physics, making searches for lepton flavour violating decays of B mesons an interesting probe for New Physics. In addition, hints of lepton non-universality in b → sll transitions (RK+, RK*0) imply the violation of lepton flavour conservation. Due to the abundance of produced B-mesons and ability to precisely study them, the LHCb experiment provides an ideal environment for searches for lepton flavour violating decays of B-mesons.
In this talk, the search for the lepton flavour violating decays B+ → K+ e±µ∓ with the LHCb experiment is presented. The analysed data set has been recorded during Run 1 and Run 2 of the LHC and corresponds to an integrated luminosity of 9.1 fb−1.
