  • Bi-large neutrino mixings by radiative magnification 
    Mohapatra R.N.; Parida M.K.; Rajasekaran G. (Indian Academy of Sciences, Bangalore, 2004)
    Starting with the unification hypothesis of mixings of quarks and leptons and small quark-like mixings at the see-saw scale, we find that two large mixings for νe, -νμ and νμ - ντ at the weak scale are obtained as a result ...
  • General relations among observables in neutral-current phenomena mediated by one or two Z bosons 
    Parida M.K.; Rajasekaran G. (Indian Academy of Sciences, Bangalore, 1979)
    If μ-e universality is assumed, there are 17 neutral-current parameters of current experimental interest, including the parity-violating nuclear force sector. We deduce the general relations among these parameters implied ...
  • High scale mixing unification and large neutrino mixing angles 
    Mohapatra R.N.; Parida M.K.; Rajasekaran G. (2004)
    Starting with the hypothesis that quark and lepton mixings are identical at or near the grand unified theory scale, we show that the large solar and atmospheric neutrino mixing angles together with the small reactor angle ...
  • Neutrino mixings and leptonic CP violation from CKM matrix and Majorana phases 
    Agarwalla S.K.; Parida M.K.; Mohapatra R.N.; Rajasekaran G. (2007)
    The high scale mixing unification hypothesis recently proposed by three of us (R.N.M., M.K.P. and G.R.) states that if at the seesaw scale the quark and lepton mixing matrices are equal, then for quasidegenerate neutrinos ...

(2009)
    This is a, summary of the beyond the Standard Model (including model building) working group of the WHEPP-X workshop held at Chennai from January 3 to 15. 2008. © Indian Academy of Sciences.
  • Radiative magnification of neutrino mixings in split supersymmetry 
    Mohapatra R.N.; Parida M.K.; Rajasekaran G. (2005)
    Radiative corrections to neutrino mixings in seesaw models depend on the nature of new physics between the weak and the grand unified theory (GUT)-seesaw scales and can be taken into account using the renormalization group ...
  • Radiative stability of neutrino-mass textures 
    Parida M.K.; Das C.R.; Rajasekaran G. (Indian Academy of Sciences, Bangalore, 2004)
    Neutrino-mass textures proposed at high scales are known to be unstable against radiative corrections especially for nearly degenerate mass eigenvalues. We find a mechanism in a class of gauge models including 2HDM where ...
  • Threshold effects on quasidegenerate neutrinos with high-scale mixing unification 
    Mohapatra R.N.; Parida M.K.; Rajasekaran G. (American Physical Society, 2005)
    We consider threshold effects on neutrino masses and mixings in a recently proposed model for understanding large solar and atmospheric mixing angles using radiative magnification for the case of quasidegenerate neutrinos. ...
