Abstract

Results on CP violation searches in charm decays performed by the LHCb experiment are reviewed. These include an update of the measurement of the difference in time-integrated {\em CP} asymmetry between $D^{0} \to K^{-} K^{+}$ and $D^{0} \to π^{-} π^{+}$ using $D^{0}$ from prompt $D^{*+}, am e a s u r e m e n t o f t h es am eo b ser v ab l e u s in g anin d e p e n d e n t s am pl eo f$ D^0 $f r o m se mi l e pt o ni c B d ec a y s, an d C P v i o l a t i o n se a r c h es p er f or m e d o n c ha r g e d$ D$ mesons. All results have been released since FPCP 2012.
