Description

Using 362/fb data sample of Belle II, we have studied B -> K \nu \bar{nu} decays at Belle II. In order to cope with final states with multiple neutrinos, we use two different methods for tagging, which are nearly statistically independent with each other. Combining the two methods, we find evidence for B -> K \nu \bar{nu} decays with 3.5\sigma.
