Search for the rare decay B(s)0 → e+ e− with the LHCb experiment — Johannes Albrecht, •Alexander Battig, Titus Mombächer, and Stefanie Reichert — TU Dortmund
The search for decays of the type B(s)0 → l+ l−, which are strongly suppressed in the Standard Model, provide an ideal environment for searches for New Physics. Tests of lepton flavour universality (RK, RK*) hint at a difference in the bahaviour of muons and electrons. In addition to the measurement of the branching ratio of the decay Bs0 → µ+ µ−, which has been measured to be compatible with the Standard Model, the decay B(s)0 → e+ e− provides an additional stringent test for the Standard Model.
In this talk the search for B(s)0 → e+ e− 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 5 fb−1.
