Paper Abstract

A paper describes a possibility of upgrading trigger RPC system at CMS detector for research of Heavy Stable Charged Particles (HSCPs). An experiment for the High Energy Physics (HEP) is located at CERN at the world's biggest accelerator complex mostly aimed to the research of particles and forces described in Standard Model (SM) theory. The SM explains the structure of matter but omits some important factors as the Gravity. There are three main branches of the New Physics that expand the SM: supersymmetry (SUSY), technicolors and additional dimentions. The SUSY provides the hipotetic HSCPs existence. Algorithms for search of those particles are implemented as a FPGA firmware in the RPC trigger system. Proposed methods expand the functionality of the existing trigger firmware. They are supposed to implement the simultaneous HSCPs and muons identification. The proposed solutions increase the trigger time resolution that is the important element of the system competitiveness to the other systems of the CMS detector. They also enable distinction between the particles produced inside the detector as the result of the collisions and the particles generated outside the detector that fly back through it. Such generation can be the result of the HSCP the reaction with rocks surrounding the detector cavern. The described methods are supposed to provide the selective trigger for the data most wanted for the HEP experiments research that could introduce the experimental science to the Great Unification.
