Measurement of self-coupling of Higgs from non-resonant production of Higgs pair at the LHC.

	Measurement of the trilninear self-coupling of Higgs is the most importnt physics mandate at the LHC at present. It can be directly accessed in proton-proton collision by

	inclusive Higgs pair (HH) production.  A search for the non-resonant HH production via gluongluon fusion and as well as Vector Boson Fusion processes has been performed by CMS experiment using LHC Run-2 proton-proton collision data at center of mass energy of √s=13 TeV using bb¥¥ final state. Further, VBF HH process uniquely provides direct access to the coupling involving two Higgs and two Vector Bosons (HHVV). This talk will describe the highlights of the analysis strategy and the results on the inclusive cross section for HH production as we ll as various coupling parameters.
