Can Leptonic Mixing Matrix have a Wolfenstein Form?

Ankur Panchal, G. Rajasekaran, Rahul Srivastava

We analyze the possibility of the leptonic mixing matrix having a Wolfenstein form at the Grand Unified Theory scale. The renormalization group evolution of masses and mixing angle…

Does the Wolfenstein form work for the leptonic mixing matrix?

G. Rajasekaran

Starting with the Wolfenstein form for the leptonic mixing matrix we show that renormaliztion group evolution brings that to the observed large mixing at low energies.

Anomalous Kolar Events and Dark Matter Decay in Dwarf Spheroidal Galaxies

R. Thiru Senthil, G. Rajasekaran

Using the Fermi LAT data on the gamma ray emission from dwarf spheroidal galaxies, we get the upper bound on the probability of gamma rays from dark matter decay for the validity o…

Stable or Unstable Light Dark Matter

Ernest Ma, M. V. N. Murthy, G. Rajasekaran

We consider the case of light dark matter ( GeV). We discuss a simple model of scalar self-interacting dark matter, as well as a related model of unstable long-lived…
