Dark matter is subdominant in the central part of Galaxy. It strongly suppresses it dynamical effect and causes large uncertainty in dark matter density and velocity distribution. At this uncertainty one can explain the positron line excess, observed by INTERGRAL, for a wide range of $m_o$ given by the curve with minimum at $m_o = 1.25 \TeV$. However, recent analysis of possible dark matter distribution in the galactic bulge favor minimal value of its central density.

The~comparison of the~experimental cross section upper limit with the~theoretical next-to-leading order cross section for pair production of $H^{\pm\pm}$ bosons. The~theoretical cross sections are computed separately for bosons with left-handed ($H^{\pm\pm}_L$) and right-handed ($H^{\pm\pm}_R$) couplings, and summed for the~case that their masses are degenerate,~\cite{Acosta:2005np}.

The~signal efficiencies for different masses and charges of the~multi-charged particles for the~DY production model. Double charged particles are denoted as ``$z=2$'' (red points and line). The~picture is taken from~\cite{Aad:2015oga}.

Observed $95\%$ CL cross-section upper limits and theoretical cross-sections as functions of the multi-charged particles mass. Again, the~double charged particles are denoted as ``$z=2$'' (red points and lines). The~picture is taken from~\cite{Aad:2015oga}.

Observed $95\%$ CL cross-section upper limits and theoretical cross-sections as functions of the multi-charged particles mass in CMS search at the~$\sqrt{s}=8$~\TeV{}. The~double charged particles are denoted as ``$|Q|=2e$''. The~picture is taken from~\cite{Chatrchyan:2013oca}.
