On the difference of time-integrated CP asymmetries in D0→K+K− and D0→π+π− decays: Unparticle physics contribution

Abstract

The LHCb Collaboration has recently measured the difference of time-integrated CP asymmetry in D0→K+K− and D0→π+π− decays, more precisely. The reported value is ΔACP=−0.10±0.08(stat)±0.03(syst)% which indicates no evidence for CP violation. We consider the possible unparticle physics contribution in this quantity and by using the LCHb data try to constrain the parameter space of unparticle stuff. Keywords: CP violation, D meson decay, Unparticle physics
