On the difference of time-integrated CP asymmetries in D-0 -> K+K- and D-0 -> pi(+)pi(-) decays: Unparticle physics contribution

摘要

The LHCb Collaboration has recently measured the difference of time-integrated CP asymmetry in D-0 -> K+K- and D-0 -> pi(+)pi(-) decays, more precisely. The reported value is Delta A(CP) = -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. (C) 2017 The Authors.
