Four top quark production at Run3 in the single-lepton final state with CMS 

The top quark is the heaviest elementary particle in the Standard Model (SM) with an experimental value of 172.5 GeV. Accurately measuring the top's properties are of critical importance to multiple interesting phenomena in SM and Beyond SM physics. In CMS, the production of four top quarks, one of the rarest SM processes in the top sector that are accessible at the Large Hadron Collider (LHC), has been observed with Run 2 data at $\sqrt{s} = 13$ TeV. With the data collected during the current Run 3 period at $\sqrt{s} = 13.6$ TeV and an expected increase in luminosity, better and more accurate measurements can be made. We present a study to improve the reconstruction of the Standard Model four top quark process with the single lepton final state channel where one of the four tops decay leptonically and the other 3 decay hadronically. We study simulations corresponding to the data collected during Run 3 for the CMS Experiment at $s= \sqrt{13.6}$ TeV with a total of 62 fb$^{-1}$ from 2022 to 2023. The study utilizes modern techniques to optimize the measurement including state of the art Neural Network models and improved methods for increased sensitivity of the four top candidate events.
