Description
The Belle II experiment at the SuperKEKB asymmetric-energy electron-positron collider has been collecting the world’s highest-intensity collisions at the $\Upsilon$(4S) since 2019. A data set comparable in size to that of predecessor experiments, and collected with the new detector, enables unique or world-leading results. Examples include indirect searches for non-standard-model physics in the weak interactions of quarks, determinations of fundamental standard-model parameters, and direct searches for low-mass dark matter. This talk presents a selection of recent results and briefly discusses future perspectives.
