Search for the B0→ D0D0 decay with the LHCb experiment. — •Jonah Blank and Sophie Hollit — 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 decays are interesting to examine C P violation and further constrain the unitarity triangle.
While decays to charged D± mesons have already been well measured, the B0→ D0D0 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 B0→ D0D0 decay channel. The B0→ D0π+π− decay channel is utilized as a normalisation mode to cancel most uncertainties.
An update of the current status of the analysis will be presented.
