Fourth generation effects in ■_s→π~-K+ decay

王帅伟  常钦  黄金书  吕林霞  
【摘要】:We study the effects of the fourth quark generation model in ■_s →π-K+decay.Combining with the up-to-date experimental measurement for B(■_s →π-K +) and A dir cp(■_s →π-K +) by the CDF Collaboration,we derive the new bound of weak phase φ bd,which are 0 φ bd 44,321 φ bd 360 and 0 φ bd 26,342 φ bd 360 for m t = 400 and 600 GeV respectively.In these regions,B(■_s →π-K +) and A dir cp(■_s →π-K +) consist with the current experimental data within errors.
