Bs–B¯s mixing and its implication for Academic Article uri icon

abstract

  • We investigate the effect of the current measurement of the neutral Bs meson mass difference, Δ MBs, on SUGRA models which have non-zero values of the soft breaking terms (mL L, R R2)23 and A23u, d at the GUT scale. We use non-zero values of these parameters to explain the B → K π puzzle and find that even after satisfying the experimental result on Δ MBs and the branching ratio (BR) of b → s γ we still can explain the puzzle. Further we show that in this parameter space it is possible to accommodate the large BR of B → η′ K and the current experimental data for CP asymmetries of B → η′ K0 and B → φ{symbol} K0. The predicted value of sin (2 βeff)η′ K0 is about 0.52-0.67. © 2006.
