| Status of flavor anomalies with Belle & Belle II
/ Youngjoon Kwon
[BELLE2-TALK-CONF-2023-067]
Originally assigned for 25+5 min, but as one of the talk in the same session is cancelled, the organizer gave me more time (~10 min.). As the organizer wanted me to cover at least one result from LHCb, I added a single page for LHCb R(D*)-R(D) result, showing a plot from their paper. As I sit through the conference for the first three days, I find the audience may need somewhat gentler intro, so I added a few pages on it. Otherwise, the physics contents from Belle II and Belle have not been changed. (I moved the B->D*lnu for Vcb to Appendix.)
