Title: “Recent results from Belle II experiment”

Abstract:
The Belle II experiment at the SuperKEKB collider provides a unique environment for precision studies in flavor physics, particularly in semileptonic and electroweak penguin decays of B mesons with missing energy. This presentation will cover recent measurements, including the extraction of the CKM element |V_cb| in B → Dℓν, tests of lepton flavor universality such as R(X) and R(D(*)), and the determination of the branching fraction for the fully leptonic mode B → τν. Additionally, the latest results on the rare decay B → Kνν and their interpretation will be discussed. The seminar will also outline future prospects, detector upgrades, and the impact of these improvements on upcoming Belle II analyses.
