The status of the CMS RPC Gas Gain Monitoring (GGM) system developed at the Fras-cati Laboratory of INFN (Istituto Nazionale di Fisica Nucleare) is reported on. The GGM system is a cosmic ray telescope based on small RPC detectors operated with the same gas mixture used by the CMS RPC system. The GGM gain and efficiency are continuously monitored on-line,… (More)
We review genetic programming principles, their application to FOCUS data samples , and use the method to study the doubly Cabibbo suppressed decay D + → K + π + π − relative to its Cabibbo favored counterpart, D + → K − π + π +. We find that this technique is able to improve upon more traditional analysis methods. To our knowledge, this is the first… (More)
Results from the gas gain monitoring (GGM) system for the muon detector using RPC in the CMS experiment at the LHC is presented. The system is designed to provide fast and accurate determination of any shift in the working point of the chambers due to gas mixture changes.
