Discussion Overview
The discussion revolves around identifying hadrons that decay into muons at LHC conditions, particularly those that decay before reaching the detector. The focus is on understanding the significance of these decays for research purposes, including their relevance to a proposed fast timing layer for phase 2 at CMS.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant mentions the need for hadrons that decay before reaching the detector, noting that K0 long is too stable for their requirements.
- Another participant suggests looking at resources like Wikipedia for lists of baryons and mesons that might meet the criteria.
- A participant points out that the branching fraction of the decay ##J/\psi \to \mu^+ \mu^-## is 6%, indicating that these particles are produced in large quantities at the LHC.
- Discussion includes the importance of muon energy, with examples given of muons produced from hadron decays at different energy levels relevant to various experiments.
- One participant emphasizes the need for a common decay process to ensure sufficient statistics without generating too many events.
- Another participant questions why the focus is solely on muons and suggests directly producing muons through processes involving J/Psi and Z particles.
- There is mention of the possibility of forcing decay modes within the CMS software, although one participant admits to having limited knowledge about it.
Areas of Agreement / Disagreement
Participants express a shared interest in finding suitable hadrons that decay into muons, but there are differing opinions on the methods and processes to achieve this. The discussion remains unresolved regarding the best approach to meet the research needs.
Contextual Notes
Participants acknowledge the lack of detailed information about the specific requirements and context of the research, which may limit the effectiveness of their suggestions.
