$C P$ Asymmetry in $B \to ϕ K_{S}$ Decays in Left-Right Models and its Implications for $B_{s}$ Decays

In left-right models the gluonic penguin contribution to

b \to s \bar{s} s

transition is enhanced by

m_{t} / m_{b}

due to the presence of (

V + A

) currents and by large values of loop functions. Together those effects may overcome the suppression due to the small left-right mixing angle

ξ ≲ 0.013

. Two independent new phases in the

B \to ϕ K_{S}

decay amplitude appearing in a large class of left-right models can modify the time-dependent

C P

asymmetry in this decay mode by

O (1)

and explain the recent BABAR and Belle

C P

asymmetry measurements in this channel. This scenario implies observable deviations from the standard model also in

B_{s}

decays which could be measured at Tevatron and LHC.
