Footprint of triplet scalar dark matter in direct, indirect search and invisible Higgs decay

Figures & data

Figure 1. Relic density as a function of DM mass for all the valid values of ${\mathit{\lambda }}_3$. The shaded cyan panel indicates regions in which $T^0$ particles contribute more than 10 per cent of dark matter density.

Figure 2. The relic density plot in ${\mathit{\lambda }}_3$ and DM mass plane. The shaded blue region leads to more participation in relic density.

Figure 3. Shaded areas depict ranges of parameter space in mass of DM and ${\mathit{\lambda }}_3$ coupling plane which are consistent with experimental measurements of $Br(h\to \mathrm{I}nvisible)$, upper limit on ${\mathit{\sigma }}_{\mathrm{FermiLAT}}$ (indirect detection) and ${\mathit{\sigma }}_{\mathrm{LUX}}$ (direct detection).

Figure 4. The thermal average annihilation cross section of $T^0$ (DM) to $\mathit{\gamma }\mathit{\gamma }$ as a function of the DM mass for several values of ${\mathit{\lambda }}_3$. The solid red lines shows the upper limits on annihilation cross section which have borrowed from Ackermann et al. (2013).
