Measurement of spin of Higgs boson using H -> W+W- decay mode at the CMS experiment.
ABSTRACT :
Higgs mechanism , Theory proposed by Peter Higgs and Francois Englert in 1970 suggested particle ’Higgs’ which contributes mass of subatomic particle. Theory was confirmed experimentally in ATLAS and CMS experiments at LHC on 4 July 2012. Higgs boson is scalar particle (spin 0) with even parity according to Standard Model of Physics . My aim to measure spin of Higgs boson at mass 125.7 Gev in H→W+ W –→l ν l ν decay process .I will be present Analysis update of measurement of spins (spin 0 and spin 2) and details of Higgs validation for Data and Monte Carlo.
