Search for the B0→ D0D0 decay with the LHCb experiment. — •JONAH BLANK and SOPHIE HOLLITT — Experimentelle Physik 5, TU Dortmund
With precise measurements of B meson decays the LHCb experiment can test the integrity of the Standard Model of particle physics. Especially B→ D D are interesting to examine C P violation and further constrain the unitarity triangle. While decays to charged D± mesons have already been found and well measured, the B→ D0D0 decay channel has not yet been observed by any experiment.
In this analysis, data collected by the LHCb experiment at √s= 7,8 and 13 TeV corresponding to 9 fb−1 is used to search for the B0→ D0D0 decay channel. The B0→ D0π+π− decay channel is used as a normalisation mode to control high theory uncertainties. The current status of the analysis will be presented.
