SUMMARY:Search for massive new physics particles using boosted top quarks a
	nd Higgs bosons with the CMS detector at the CERN LHC
DESCRIPTION:Featuring Dr. Devdatta Majumder\nHosted by: Tulika Bose\n\nPart
	 of the HEE Seminar Series.\n\nMassive new particles are predicted in many 
	beyond standard model (BSM) theories that are well within the energy reach 
	of the CERN Large Hadron Collider (LHC). The CMS experiment has been collec
	ting LHC proton-proton collision data at a centre-of-mass energy of 13 TeV 
	since 2015. In this talk\, I will review some recent CMS searches for BSM p
	articles that decay to a pair of Higgs bosons\, or a Higgs boson and a top 
	quark\, using LHC data from 2015-2016. The Higgs boson and the top quark ar
	e the two most massive standard model particles and frequently occur in the
	 decay processes of BSM particles. A massive decaying particle can impart s
	ufficient kinetic energy to the daughters so that the decay chain is highly
	 collimated\, and can produce spectacular signatures in the detector\, part
	icularly when the decay is entirely hadronic\, producing Higgs boson jets o
	r top quark jets. The LHC data analyses are increasingly using novel detect
	ion techniques like Higgs jet and top jet tagging to search for BSM particl
	es such as vector-like quarks\, or gravitons in extradimensional models. I 
	will discuss these tagging techniques used at the CMS experiment and how th
	ey are driving the new physics search frontier at the LHC.
