20 Oct 2014 | | Abstract: | We report on the simulation studies on the possibility of dark matter
particle (DMP) decaying into leptonic modes. While not much is known about the
properties of dark matter particles except through their gravitational effect,
it has been recently conjectured that the so called "anomalous Kolar Events"
observed some decades ago may be due to the decay of unstable dark matter
particles (M.V.N. Murthy and G.Rajasekaran, Pramana, {f 82}, 609 (2014)). The
aim of this study is to see if this conjecture can be verified at the proposed
Iron Calorimeter (ICAL) detector at INO. We study the possible decay to
leptonic modes which may be seen in this detector with some modifications. For
the purposes of simulation we assume that each channel saturates the decay
width for the mass ranging from $1-50
m{GeV/c^2}$. The aim is not only to
investigate the decay signatures, but also, more generally, to establish lower
bounds on the life time of DMP even if no such decay takes place. | | Source: | arXiv, 1410.5182 | | Services: | Forum | Review | PDF | Favorites | |
