LHCb: Search for CP violation in $D^+ \to K^-K^+\pi^+$ decays at LHCb

A model-independent search for direct CP violation in the Cabibbo suppressed decay $D^+ \to K^-K^+\pi^+$ in a sample of approximately 370,000 decays is described. The normalized Dalitz plot distributions for $D^+$ and $D^-$ are compared using four different binning schemes that are sensitive to different manifestations of CP violation. No evidence for CP asymmetry is found.
