Search for CP violation through an amplitude analysis of D0->K+K-pi+pi- decays at LHCb

Maxime Schubiger

This thesis presents a search for

CP

violation in the

D^0\rightarrow K^+K^-\pi^+\pi^-

Cabibbo-suppressed decay mode using an amplitude analysis. New sources of

CP

violation have to be discovered in order to explain the matter-antimatter imbalance obs ...
