Query: Supersymmetry and neutrino mass   The existence of neutrino mass and mixing is a strong pointer towards physics
beyond the standard model. An overview of the possibility of having neutrino
masses in supersymmetric theories is attempted here. Some of the recent works
reviewed suggest Dirac masses, whereas others include Majorana masses as well.
Side by side, it is shown how R-parity violating supersymmetry opens new
avenues in the neutrino sector. Reference is also made to light sterile
neutrinos, nearly degenerate neutrinos and neutrinos acquiring masses from hard
supersymmetry breaking terms which are suppressed by the Planck scale. In
several of the cases, it is pointed out how the models that give neutrino
masses and mixing have independent motivations of their own, and can be tested
in accelerator experiments.
