  • An SO(10) GUT with see-saw masses for all fermions 
    Desai B.R.; Rajasekaran G.; Sarkar U. (2005)
    We propose an SO(10) grand unified theory in which all fermions acquire see-saw masses. We include only two Higgs scalars, a 210-plet and a 16-plet. In addition to the regular fermions we include one singlet per generation, ...
  • Neutrino condensate as origin of dark energy 
    Bhatt J.R.; Desai B.R.; Ma E.; Rajasekaran G.; Sarkar U. (2010)
    We propose a new solution to the origin of dark energy. We suggest that it was created dynamically from the condensate of a singlet neutrino at a late epoch of the early Universe through its effective self-interaction. ...
  • Seesaw fermion masses in an SO(10) grand unified theory 
    Bhattacharya K.; Sarkar U.; Das C.R.; Rajasekaran G.; Desai B.R. (2006)
    In this work we study an SO(10) GUT model with minimum Higgs representations belonging only to the 210 and 16 dimensional representations of SO(10). We add a singlet fermion S in addition to the usual 16 dimensional ...
