(2015). Search for CP violation in D0→ π− π+ π0 decays with the energy test. Physics Letters B, 740, 158-1670370-2693http://hdl.handle.net/10347/21856A search for time-integrated CPviolation in the Cabibbo-suppressed decay D0→π−π+π0is performed using for the first time an unbinned model-independent technique known as the energy test. Using proton–proton collision data, corresponding to an integrated luminosity of 2.0fb−1collected by the LHCbdetector at a centre-of-mass energy of √s=8TeV, the world’s best sensitivity to CPviolation in this decay is obtained. The data are found to be consistent with the hypothesis of CPsymmetry with a p-value of (2.6 ±0.5)%eng©2014 The Authors. Published by Elsevier B.V.
