Hadronic B decays

Dec 22, 2026, 9:00 AM

Description

Better simulation will allow to improve the training of the B-tagging and consequently its performance... For that, more measurements are needed...

1. B -> Lambdac X

Swarna Maharana (IITH)

This is the first analysis on inclusive we performed... the main difficulty was the handling of the cross-feed between B0 and B+, and became our default fit. Close to be unblinded, we can hear summarize the findings and how to interpret them in term of exclusive B decays.

Requests:
- explain the challenge (cross-feed) and the approach (use of excluded events), quick comparison to Paul's...

2. B -> Ds(*) X

Varsha Gautam (IITB)

3. B -> D(*) X

• MC and data difference.... (significant difference between data and our MC ?)
• Focus on the CF... at the Btag mode level

23. B -> D(*) X and Cross-feed

4. What to do with those measurements ? what else do we need ?

Karim Trabelsi (CPPM, TYL)

We discuss here what those precise measurements can bring and what could be a strategy to update our knowledge (decay table) of the B decays...
