| 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.)

The world average of previous R(D(*)) measurements, defined as R(D(*)) = BR(B -> D(*) tau nu) / BR(B -> D(*) l nu) with l = e, mu, shows a 3.3 sigma deviation from Standard Model predictions, which could indicate some New Physics phenomenon, such as the existence of Leptoquarks. [...]

The so far unresolved question of the nature of dark matter has led to the development of a multitude of particle physics models that all meet current experimental and theoretical constraints, but differ greatly in the experimental signatures they predict. [...]

We study the decay of 𝐵0 → 𝐽⁄𝜓 eta based on the Belle data samples at the Υ(4𝑆) resonance and compare to the results in PRL 2007 “Observation of the Decay 𝐵0 → 𝐽⁄𝜓 eta ” and PRD 2012 “Measurement of 𝐵0 → 𝐽⁄𝜓 eta(′) and constraint on the eta − eta′ mixing angle”. [...]
