OPTIMIZATION OF SEARCH VARIABLES FOR THE PAIR PRODUCTION OF FIRST GENERATION SCALAR LEPTOQUARK AT THE CMS,CERN
As a possible signature of new physics beyond the standard model (SM), we search for hypothetical
particles called “leptoquarks” that have the dual properties of both leptons and quarks.
We search for such particles in the final states of two electrons and two hadronic jets using proton-proton collision data events recorded at 13 TeV with the CMS detector at the LHC, CERN.
We optimize the value of various search variables to obtain an optimal significance for a leptoquark mass of 250 GeV/c^2 from various SM background processes.
The optimization is performed using Monte Carlo simulated data,
which can be later applied to collision data.
Further, the same procedure can be repeated for higher leptoquark masses.
Summary of interactions between particles described by the Standard Model.
Leptons and quarks naturally fit into three generations of doublets based on the way they interact with the weak force.
A 3D plot of signal significance with respect to search parameters. It can clearly be seen that the significance is maximum around the peak point.
