Status and performances of physics objects at p √s = 13 TeV for CMS

초록

The Large Hadron Collider (LHC) at CERN started the data taking at the center of mass energy 13 TeV in June 2015. After the higgs discovery, the phase of searching for higgs boson have been moved to searching for the possible new physics which might explain what the standard model can not explain such as dark matter. A top quark is believed to have a hint in this journey. To accomplish this goal using a top quark, we need to understand our detector beforehand at the new center of mass energy with the physics objects. The decay products from a top quark contain most of all physics objects we identify in our detector. We present the status and performance of physics objects with data corresponding to an integrated luminosity of 42 pb-1 collected at p √s = 13 TeV by the CMS experiment during the summer in 2015.
