Description

Kinematic effects in the Higgs boson decay to four leptons are investigated using full detector simulation combined with matrix element techniques. The analysis is optimized to enhance sensitivity to the tensor structure of Higgs boson interactions and the spin correlations present in the decay process. The study is based on data collected by the CMS experiment at the LHC. The interactions of the Higgs boson with electroweak vector bosons are studied through an effective Lagrangian framework, and the results are presented as constraints on parameters that extend beyond the Standard Model.
