Search for charged Higgs Boson in di-jet resonances along with a charged lepton at √s = 13 TeV p-p collision with the ATLAS detector

A search for dijet resonances in events with identified leptons is performed using data collected in $pp$ collisions at $ \sqrt s=13$TeV by the ATLAS detector between 2015 and 2018, corresponding to an integrated luminosity of 139 $fb^{-1}$. We examine the dijet invariant mass distribution in the range of 0.22 $< m_{jj} < $ 6.3 TeV. The analysis probes much lower mjj than traditional inclusive dijet searches and is sensitive to a large range of new physics models with a final-state lepton. This talk summarizes the latest search results that are interpolated in the context of a charged Higgs decaying to a top and bottom quarks.
