Search for the B0D0D0 decay with the LHCb experimentJohannes Albrecht, •Jonah Blank, Quentin Führing, and Sophie Hollitt — TU Dortmund University, Dortmund, Germany

With precise measurements of B meson decays the LHCb experiment can test the integrity of the Standard Model of particle physics. Especially BD D decays are interesting to examine CP violation and further constrain the unitarity triangle. While decays to charged D± mesons have already been well measured, the B0D0D0 decay channel has not yet been observed by any experiment.

In this analysis, data collected by the LHCb experiment at √s = 7, 8 TeV and 13 TeV corresponding to an integrated luminosity of 9 fb−1 is used to search for the B0D0D0 decay channel. The topologically similar B0D0π+π decay channel is utilized as a normalisation mode to cancel systematic uncertainties. An update on the current status of the analysis will be presented.
