Abstract

Charge flips occur due to mismeasurement of electrical charge of a particle by a particle accelerator. The doubly charged Higgs boson needs to decay into two leptons with the same charge and therefore, it is crucial that the charge of the leptons is measured accurately. Utilizing data from CMS at the LHC, a program was written which counts the number of charge flips of a specific interaction. The algorithm analyzes pairs of electrons and pairs of muons and checks if there was any change in the electric charge. The algorithm outputs the number of charge flips in electron pairs and muon pairs, the number of pairs that did not have any charge flips, as well as the total number of events.
