  • Neutral current cross-sections for neutrinos on protons 
    Rajasekaran G.; Sarma K.V.L. (Indian Academy of Sciences, Bangalore, 1978)
    Defining the ratios rp =σ(vp →vx)/σ(vp →μ- x) and {Mathematical expression} we obtain the bounds 0.28 ≤rp ≤ 0.61 and {Mathematical expression} using only the parton model and the data of CDHS group with iron target. We ...
  • Neutral currents in left-right symmetric gauge models 
    Bajaj J.K.; Rajasekaran G. (Indian Academy of Sciences, Bangalore, 1979)
    We analyse all the neutral-current phenomena following from the general class of gauge models based on the group SU(2)L ⊗ SU(2)R ⊗ U(1). It is found that the neutral-current couplings in these models bear a remarkable ...
  • 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. ...
  • Neutrino masses, Large mixings and phenomenology 
    Balaji, K.R.S. (, 2009-08-27)
    This thesis concentrates on a few aspects of massive neutrino physics. The effects of matter on neutrino oscillations is described, which are a consequence of massive neutrinos. A short description of the electromagnetic ...
  • 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 ...
  • Neutrino oscillation probabilities: Sensitivity to parameters 
    Indumathi D.; Murthy M.V.N.; Rajasekaran G.; Sinha N. (2006)
    We study in detail the sensitivity of neutrino oscillation probabilities to the fundamental neutrino parameters and their possible determination through experiments. The first part of the paper is devoted to the broad theme ...
  • Neutrinos from stellar collapse: Comparison of signatures in water and heavy water detectors 
    Dutta G.; Indumathi D.; Murthy M.V.N.; Rajasekaran G. (American Physical Society, 2001)
    Signatures of neutrino and antineutrino signals from stellar collapse in heavy water detectors are contrasted . with those in water detectors. The effects of mixing, especially due to the highly dense matter in the supernova ...
  • Neutrinos from stellar collapse: Comparison of the effects of three and four flavor mixings 
    Dutta G.; Indumathi D.; Murthy M.V.N.; Rajasekaran G. (2000)
    We study the effect of non-vanishing masses and mixings among neutrino flavors on the detection of neutrinos from stellar collapse by a water Cherenkov detector. We consider a framework in which there are four neutrino ...
  • Neutrinos from stellar collapse: Effects of flavor mixing 
    Dutta G.; Indumathi D.; Murthy M.V.N.; Rajasekaran G. (2000)
    We study the effect of nonvanishing masses and mixings among neutrino flavors on the detection of neutrinos from stellar collapse by a water Cherenkov detector. We consider a realistic framework in which there are three ...
  • New "square root" model of lepton family cyclic symmetry 
    Ma E.; Rajasekaran G. (American Physical Society, 2003)
    Following the newly formulated notion of form invariance of the neutrino mass matrix, a complete model of leptons is constructed. It is based on a specific unitary 3×3 matrix U in family space, such that U2 is the simple ...
  • New Algorithmic results using Noncommutative Algebraic Complexity[HBNI Th210] 
    Abhranil Chatterjee (The Institute of Mathematical Sciences, 2022)
    Algebraic Complexity is the study of the complexity of computing multivariate polynomials where the complexity of a polynomial is the number of arithmetic operations such as additions, and multiplications required to ...
