Description
The search for standard model double Higgs boson (hh) production at CMS is presented, using final states from various decay channels: HH->b b b b, b b VV, b b tau tau, and b b gamma gamma. The hh production serves to measure the self-coupling of the Higgs boson the rate of which is small in the SM. However, contributions from beyond standard models (BSM) can significantly enhance the rate. Furthermore, many BSM particles may decay to hh that can be manifested as a resonance in the hh invariant mass spectrum.
