25th meeting on physics at B factories

Date:  May 16 (Mon) 2022, 13:00-

Place: hybrid format: KEK, 3rd Building, Seminar Hall, and by Zoom

The main purpose of SuperKEKB/Belle II is to search for new physics
beyond the Standard Model through B, D and tau decays by accumulating
50 times more data than KEKB/Belle by the early 2030's.
It also aims to directly search for dark-sector and axion-like particles
by taking advantage of high luminosity e+e- collider experiments.

SuperKEKB reached the world's highest luminosity 3.8 x 10^34 /cm2/s
and Belle II has recorded the data sample of 350 /fb, so far.
Analyses using a part of the data was presented at the Moriond conference.

This series of meetings aims to provide opportunities, where theorists
and experimentalists get together and closely discuss physics at B factories.
In this 25th meeting, we will have the following invited talks:

Syuhei Iguro (Karlsruhe) "New 5 sigma discrepancy in hadronic B decays?"
Taichiro Koga (KEK)      "Summary on (semi)leptonic analyses at Moriond 2022"
Kazutaka Sumisawa (KEK)  "Summary on time dependent analyses and related topics at Moriond 2022"
Eiasha Waheed (KEK)      "Measurement of B0 -> D(*) h (h = K,pi) decays at Belle"

The working language is English, and non-Japanese participants are very welcome! The meeting will be held in a hybrid format at a seminar hall at KEK and by Zoom. Please register from "Registration" in the left menu by May 11 (Wed). After the deadline, the Zoom connection information will be sent to the participants by email.
