Bounds on the Higgs boson lifetime with H$\to $4l events

Constraints on the width of the Higgs boson, or equivalently its lifetime, are set using the H$\to $ZZ$\to $4l decay channel and the full dataset recorded by the CMS experiment during the LHC Run 1, corresponding to an integrated luminosity of 5.1 fb-1 at a center-of-mass energy of 7 TeV and up to 19.7 fb-1 at 8 TeV. The upper bound on the width is set using the off-shell production technique.
