The new particle accelerator, Large Hadron Collider (LHC) , will start operating at center-of-mass energy 14 TeV in summer 2008 at CERN (European Organization for Nuclear Research) in Switzerland, allowing the study of physics in the TeV range. My research goal at LHC is the clarification of the two big open questions in High Energy Physics today: What is the origin of mass? and What new particles lie beyond the Standard Model? My own approach to answering these questions is a synthesis of two main lines of research: Understanding of particle responses of the CMS detector and using it in searches for Higgs boson and Physics beyond the Standard Model at LHC.
