| 英文摘要 | The results of a first search for cp violation in the production and decay of top quark-antiquark (t (t) over bar) pairs are presented. the search is based on asymmetries in t-odd, triple-product correlation observables, where t is the time-reversal operator. the analysis uses a sample of proton-proton collisions at root s = 8 tev collected by the cms experiment, corresponding to an integrated luminosity of 19.7fb(-1). events are selected having one electron or muon and at least four jets. the t-odd observables are measured using four-momentum vectors associated with t (t) over bar production and decay. the measured asymmetries exhibit no evidence for cp-violating effects, consistent with the expectation from the standard model. |
