A search for violation of the charge-parity C\!P symmetry in the D^+\rightarrow K^-K^+\pi^+ decay is presented, with proton-proton collision data corresponding to an integrated luminosity of 5.4 fb^{-1}, collected at a center-of-mass energy of 13 TeV with the LHCb detector. A novel model-independent technique is used to compare the D^+... Show more
