Description
The production of a pair of Z-bosons in the llυυ channel (l = e, μ) is studied with the conditions of proton-proton collisions at a centre-of-mass energy of 13 TeV. The generation of signal and background events is performed using the MadGraph5_aMC@NLO Monte Carlo event generator. The Pythia8 and Delphes3 frameworks are used for event showering, hadronization, and detector response simulation.
This report describes an improved cut-based optimization method to maximize signal significance, where signal significance is considered as a multivariate function of the optimized variables.
The described method makes it possible to find the best combination of cuts for kinematic variables corresponding to the best signal/background ratio. An additional option of the method is the ability to find cuts that satisfy various conditions, such as a limit on the number of minimum signal events.
