Redo the AP using expected 2024 data-taking conditions.
Interested in the nature of the \bar{B}_s^0 \rightarrow D_{s}^{*+} (\rightarrow D_s^+ \gamma) \bar{\nu}_l l^- reconstructed either using the CALO or the conversion gamma photon. The purpose is to determine if reconstructing with the photon conversion its background is much lower than reconstructing using the CALO photon.
The background decays are:
\bar{B}_s^0 \rightarrow D_{s}^{*+} (\rightarrow D_s^+ \pi^0) \bar{\nu}_l l^-
- Events are selected by the B2DMuNuX stripping lines. We add another pion for the full selection.
Instructions
When creating your merge request:
- Add a label for your WG
- Mark as "Draft:" until you're happy with the CI results
- If the merge request supersedes a previous one, add a comment at the end of the header:
(supersedes !<MR number>). Please state explicitly in the description if the superseded ntuples can be deleted immediately, or after the new merge request is finalised
When ready:
- Remove the "Draft:" from the title:
- Assign the merge request to you working group's DPA/RTA liaison
To find your working group's DPA/RTA liaison, see this page:
