Higgs / Search for Higgs decay to charm quark pair at LHCb

LHCb is a spectrometer that covers the forward region of proton-proton collisions, in the pseudo rapidity range from 2 to 5. Thanks to its excellent vertex reconstruction system, it has already demonstrated its capability to identify heavy flavour jets. Moreover, the c-jet identification (c-tagging) is a crucial ingredient for the search of H->cc at LHCb. In this talk, the c-tagging algorithms used at LHCb will be illustrated, as well as new methods based on machine learning techniques that exploits the jet substructure. The prospects on the search for H->cc in future upgrades will be given.
