英文摘要 | Recent CDF and D0 measurements of B-s(0)-(B) over bar (0)(s) mixing make it possible to search for CP violation and test CPT symmetry in a variety of B-s decays. Considering both coherent B-d(0)(B) over bar (0)(d) decays at the Upsilon(4S) resonance and coherent B-s(0)(B) over bar (0)(s) decays at the Upsilon(5S) resonance, we formulate their time-dependent and time-integrated rates by postulating small CPT violation in B-d(0)-(B) over bar (0)(d) and B-s(0)-(B) over bar (0)(s) oscillations. We show that the opposite-sign dilepton events from either C-odd or C-even B-q(0)(B) over bar (0)(q) states (for q=d or s) can be used to determine or constrain the CPT-violating parameter at a super-B factory. The possibility of distinguishing between the effect of CPT violation and that of Delta B=-Delta Q transitions is also discussed. |
