Search for heavy BSM particles coupling to third generation quarks at CMS

Recent results from searches for beyond standard model particles decaying to quarks of the third generation with data collected by the CMS experiment are presented. For all searches proton-proton collision data at a center-of-mass-energy of 13 TeV with an integrated luminosity of 137 fb$^{-1}$ are analyzed. In addition, the state-of-the-art techniques in the identification of boosted objects and pileup mitigation which are used in the analyses are discussed. The searches can be grouped in three different categories: excited bottom quarks, heavy gauge boson and vector-like quarks.
