Super-factory of bottomed hadrons Belle II

In 2018, the Belle II experiment, aimed at detailed studies of B-mesons, started operation at the Super-KEKB electron–positron collider at KEK (Japan). This was preceded by the long and quite successful work of the B-factories of previous generations, including the Belle experiment, to which Belle II is a successor. This experiment is unique, having no counterparts or competitors in the world. The spectrum of problems it is aimed at is quite broad: from studies of hadronic states containing heavy quarks to precision measurements and the search for New Physics beyond the Standard Model. This review describes specific features of the Belle II experiment, its ambitious goals and specific tasks, expected results of its work, and hopes related to its successful implementation.
