Abstract: Flavor changing neutral current b to s(d) decay, particularly radiative and electroweak penguin processes, will continue to be of great interest as a probe to search for beyond the Standard Model physics. Lately there have been several anomalies observed in the b to s transition at the LHCb experiment in an angular observable, P5′ and lepton universality measurements. The Belle II experiment will take an important role providing independent cross checks for these anomalies. This article describes how the Belle II physics program can be complementary to that of LHCb, and the Belle II ongoing studies and prospects on radiative and electroweak penguin processes in early and final dataset of 50 ab−1
