Discussion Overview
The discussion revolves around the feasibility of conducting local physics analysis using the CMS software from the LHC at CERN. Participants explore the requirements for accessing the software and data, as well as the limitations of performing analysis outside of the CMS collaboration.
Discussion Character
Main Points Raised
- One participant inquires about downloading the CMS software for local use and performing physics analysis.
- Another participant asserts that downloading the software is not possible without being part of the CMS Collaboration and emphasizes the necessity of access to large datasets.
- A different participant mentions that some older experiments may have released parts of their data and analysis software, but questions the capability of local computers to handle meaningful analysis due to dataset sizes.
- Frustration is expressed regarding the process of obtaining a primary CERN account, with a question about whether physical presence at CERN is required.
- A participant explains that joining an experiment requires a commitment of time and financial contributions, highlighting the extensive effort involved in operating the detectors.
- Another participant suggests that local analysis could be conducted using individual packages for Monte Carlo data generation, referencing specific software tools and the availability of training data on the CMS website.
- One participant reiterates that access to real data is contingent upon joining an experiment.
Areas of Agreement / Disagreement
Participants generally agree that access to the CMS software and real data is restricted to members of the CMS collaboration, but there is disagreement about the potential for local analysis using alternative methods or datasets.
Contextual Notes
Limitations include the requirement for collaboration membership to access real data, the size of datasets, and the potential challenges associated with using analysis software on local machines.
