Abstract: The Belle II experiment at the SuperKEKB collider is a major upgrade of the KEK B factory in Tsukuba, Japan. The machine is designed for an instantaneous luminosity of 8×1035 cm−2s−1 and the experiment is expected to accumulate a data sample of about 50 ab−1 in 5 years running. With this amount of data, decays sensitive to physics beyond the Standard Model can be studied with unprecedented precision. One promising set of modes are physics processes with missing energy such as B→τν, B→D(∗)τν and B→K(∗)νν¯. The Belle II data also allows searches for the dark photon, the gauge mediator of a hypothetical dark sector, which recently received much attention in the context of dark matter models.
