Rescattering effects in b→ s processes
arxiv(2024)
Abstract
The measurements in b→ s penguin-dominated decays are widely recognized
as promising avenues for searching for New Physics by studying the deviation
from theoretical estimations within the Standard Model. However, most current
estimations focus only on short-distance interactions, and the influence
oflong-distance interactions may exclude the impact of new physics. This
suggests that it is essential to estimate the long-distance contribution before
probing New Physics in penguin-dominated decays. We highlights an oversight
regarding long-distance interactions, which significantly contribute to the
decay B_s→ K^*0K̅^*0. Both short-distance and long-distance
interactions play crucial roles in this decay. We give estimations of the
branching ratio and longitudinal polarization of B_s→ K^*0K̅^*0,
which is consistent with experimental observations.
