Description

With the Belle II and Belle experiments, we have a cleanly defined e+e- initial state and a nearly hermetic detector of almost 4\pi solid-angle coverage.  This is a great advantage for studying final states that include missing particles where we use the information from missing energy and momentum.  In this talk, we show some of the recent results from Belle II involving missing-energy final states.  In particular, we present the updated B -> K \nu \bar{\nu} result which was first presented in August, 2023 (arXiv:2311.14647).
