Inverse beta-decay in magnetic fields
Kaushik Bhattacharya, Palash B. Pal
We calculate the cross section of the inverse beta decay process, , in a magnetic field which is much smaller than . Using exact solutions of the Dirac equat…
Faraday effect : a field theoretical point of view
Avijit K. Ganguly, Sushan Konar, Palash B. Pal
We analyze the structure of the vacuum polarization tensor in the presence of a background electromagnetic field in a medium. We use various discrete symmetries and crossing symmet…
Determination of cosmological parameters: an introduction for non-specialists
Palash B. Pal
I start by defining the cosmological parameters and . Then I show how the age of the universe depends on them, followed by the evolution of the scale parameter of t…
Particle dark matter: an overview
Palash B. Pal
I discuss some compelling suggestions about particles which could be the dark matter in the universe, with special attention to experimental searches for them.
Non-universal gravitational couplings of neutrinos in matter
Jose F. Nieves, Palash B. Pal
When neutrinos travel through a normal matter medium, the electron neutrinos couple differently to gravity compared to the other neutrinos, due to the presence of electrons in the…
