Warm Dark Matter in Two Higgs Doublet Models
K. S. Babu, Shreyashi Chakdar, Rabindra N. Mohapatra
We show that a neutral scalar field, σ, of two Higgs doublet extensions of the Standard Model incorporating the seesaw mechanism for neutrino masses can be identified as a consiste…
Dark Matter, Parallel Universe and Multiple Higgs Signals at the ILC
Shreyashi Chakdar, Kirtiman Ghosh, S. Nandi
The existence of dark matter is now well established by several indirect experiments. Several candidates for dark matter has also been proposed. However, the dark matter can just b…
A model for Dirac neutrino mass matrix with only four parameters
Shreyashi Chakdar, Kirtiman Ghosh, S. Nandi
The exchange symmetry between the muon neutrino and the tau neutrino for the neutrino mass matrix has been very useful in understanding the near maximal atmospheric neutrino mixing…
A predictive model of Dirac Neutrinos
Shreyashi Chakdar, Kirtiman Ghosh, S. Nandi
Assuming lepton number conservation, hermiticity of the neutrino mass matrix and exchange symmetry, we show that we can determine the neutrino mass matrix completely fr…
