description This project is related to the current CMS analysis on the measurement of CP property of the Higgs boson of 125 GeV using gg fusion production process in association with two jets. The distribution of the azimuthal angle between two outgoing jets (Δφjj ), sensitive to the CP property of the Higgs boson, using date acquired from Monte Carlo simulations, that are analyzed in ROOT framework. The sensitivity is increased with the increase of the jet separation in rapidity (Δηjj) or with the increase of the dijet effective mass (mjj). Firstly, cuts are applied in order to obtain symmetrical distribution of Δφjj (which corresponds to CP conservation). Then, it is checked if Δηjj and mjj cuts are equivalent, and if the condition for the number of jets greater than 2 violates the symmetrical distribution of Δφjj[1],[2]. Finally, additional cuts in rapidity of Higgs boson and hyper jets are applied for number of jets greater than 2.
