Higgs pair production from color octet scalars and vectors

Abstract

Higgs pair production is studied in the extension of the Standard Model by color octet scalar and vector particles in TeV mass range for the LHC. The relevant parameters are their masses and portal couplings to the Higgs boson.The rate is enhanced considerably in some parts of the parameter space compared to the SM which are allowed by the latest measured bounds on the Higgs decay to $Z{Z}^{\ast }$. The model will be tested experimentally at the upcoming LHC run.
