ECFA H->ss Focus Group - Open Meeting
Description
The main goal of this meeting is to present the state-of-the-art and discuss future possibilities for studies of H->ss and strange tagging with the community excited about the topic in view of the Update of the European Strategy for Particle Physics.
Participants
Hss topical meeting
- Timeline: full consideration for studies submitted by October. If we know of studies that can come later (by December), we should mention them in the October report and then update results by December. In this way, we can ensure that are still known.
- Physics results: for the ECFA report we can make a nice summary Table/Plot to include the various constraints that are now available from the various detector configurations (this will also allow to avoid confusion between BR, ks, etc)
- Discussion on what is a reasonable number for the ks enanchement that is not already excluded (or will be) by kc bounds? SFV can still preserve symmetries while allowing for independent up or down enhancements. Other models could do it, too.
- Clarify this aspect again in the report
- An important take away from Peter: "PID is the sine qua non. Absolutely crucial."
- Next steps: iterate on fragmentation models to change at generation level and repeat the studies we have to see how sensitive we are to this
- PID reco: add dN/dx plot to the combination (PID vs p) so that a comparison can be made with the RICH performance
- Also to go in the report
- RICH: nice material budget plot exist, discussions on whether removing cooling (saving material) and adding SiPMs hermetically (costs more) to reject noise via timing is better than keeping cooling to reject noise.
- In the report, explain advancement in RICH design and also DRD4 efforts for innovative RICH and photon detectors
