| 英文摘要 | Violations of cpt symmetry and lorentz invariance are searched for by studying interference effects in b-0 mixing and in b-s(0) mixing. samples of b-0 -> j/psi k-s(0) and b-0(s) -> j/psi k+k- decays are recorded by the lhcb detector in proton-proton collisions at center-of-mass energies of 7 and 8 tev, corresponding to an integrated luminosity of 3 fb(-1). no periodic variations of the particle-antiparticle mass differences are found, consistent with lorentz invariance and cpt symmetry. results are expressed in terms of the standard model extension parameter delta a(mu) with precisions of o(10(-15)) and o(10(-14)) gev for the b-0 and b-s(0) systems, respectively. with no assumption on lorentz (non) invariance, the cpt-violating parameter z in the b-s(0) system is measured for the first time and found to be re(z) = -0.022 +/- 0.033 +/- 0.005 and im(z) = 0.004 +/- 0.011 +/- 0.002, where the first uncertainties are statistical and the second systematic. |
