Higgs pair production from color octet scalars and vectors

TL;DR

This paper investigates how extending the Standard Model with color octet scalars and vectors can significantly enhance Higgs pair production rates at the LHC, providing testable predictions for upcoming experiments.

Contribution

It introduces a model with color octet scalars and vectors, analyzing their impact on Higgs pair production and identifying parameter regions with enhanced production rates.

Findings

Higgs pair production rate can be significantly increased in certain parameter regions.

The model's predictions are consistent with current Higgs decay bounds.

Upcoming LHC runs can test these new particles and their effects.

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 $ZZ^*$. The model will be tested experimentally at the upcoming LHC run.
