Sumario: | Searching for new resonances is one of the ways at the Large Hadron Collider to look for new physics beyond the standard model (BSM), put forward by many theoretical models. Such BSM models predict for instance the existence of substructure of quarks and the quantum black holes, with their signature manifesting in different final states in proton-proton collisions at the LHC. A search for a resonance in the $\gamma+$jet final state is performed using the CMS collision data at a center-of-mass energy of 13 TeV corresponding to luminosity of 138 fb$^{-1}$. If the resonance exists, the signal would appear as a bump over the invariant mass distribution of the known standard model (SM) background processes. The SM background estimation is performed using data and exclusion limits are set on the model parameters in the absence of a signal in the data. |
