A Study of Top Quark pair using CMS Data

The Large Hadron (LHC) is the highest-energy particle collider ever made. It was built by the European Organization for Nuclear Research (CERN) from 1998 to 2008, in collaboration with around 100 countries. The LHC lies in a tunnel 27 km in circumference and 100 m underground on Franco-Swiss border near Geneva, Switzerland. The Compact Muon Solenoid (CMS) is one of the general-purpose experiment at the LHC. It has recently discovered the Higgs Boson, the only missing piece of Standard Model (SM). LHC is also a Top Quark factory. Top Quark is the heaviest of all known elementary particles and has very short life time. It couples strongly to Higgs Boson and sensitive to New Physics. Therefore the study of Top Quark properties is very important. In this work different parameters of Top Quark, such as Mass, Transverse momentum, Energy etc, are studied.
