Abstract
In this talk, we will review Inert Triplet Model (ITM) which provide candidate for dark matter (DM) particles. Then we study possible decays of Higgs boson to DM candidate and apply current experimental data for invisible Higgs decay to constrain parameter space of ITM. We also consider indirect search for DM and use FermiLAT data to put constraints on parameter space. Ultimately we compare this limit with constraints provided by LUX experiment for low mass DM and invisible Higgs decay.
Highlights
There are strong evidences for non-baryonic dark matter (DM) which according to Planck satellite (Ade et al, 2014) constitute more than 0.26 of energy density in the universe
A scalar SU(2)L triplet is odd under Z2 symmetry so that they cannot decay into the standard model (SM) particles, and the neutral component of the triplets plays the role of DM
Concluding remarks In this letter, we have presented an extension of SM which includes a SU(2)L triplet scalar with hypercharge Y = 0, 2
Summary
There are strong evidences for non-baryonic dark matter (DM) which according to Planck satellite (Ade et al, 2014) constitute more than 0.26 of energy density in the universe. Since the Higgs boson can participate in DM–nucleon scattering and DM annihilation, current analysis of the LHC data and measurements of its decay rates would set limit on any beyond SM that provides a DM candidate. We review allowed parameters space of ITM by PLANCK data and invisible Higgs decay measurement, direct and indirect detection.
