Democratic three Higgs-doublet models: the custodial limit and wrong-sign Yukawa
Dipankar Das, Miguel Levy, Palash B. Pal +3
We study two novel aspects of democratic 3HDMs -- the custodial limit and the possibility of wrong-sign Yukawa couplings. In the custodial limit, the democratic 3HDMs can easily ne…
The incredibly strange story of Einstein's Nobel prize
Palash B. Pal
It is well-known that Einstein got the 1921 Nobel prize not for his theory of relativity, but for his theory of photoelectricity. It is not that well-known that he did not get the…
Custodial symmetry, Georgi-Machacek model, and other scalar extensions
Anirban Kundu, Poulami Mondal, Palash B. Pal
In an SU(2) gauge theory, if the gauge bosons turn out to be degenerate after spontaneous symmetry breaking, obviously these mass terms are invariant under a global SU(2) symmetry…
Covariant formulation of electrodynamics in isotropic media
Palash B. Pal
The equations of electromagnetic fields in a medium is usually written in the rest frame of the medium. We outline a method of generalizing the discussion to arbitrary inertial fra…
Generalized 331 models
Pritibhajan Byakti, Palash B. Pal
We examine different ways in which the standard model can be embedded into the gauge group. We show that there exist famili…
Photon propagation in non-trivial backgrounds
Palash B. Pal
Propagation of photons (or of any spin-1 boson) is of interest in different kinds of non-trivial background, including a thermal bath, or a background magnetic field, or both. We g…
