  • 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 ...
  • 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 ...
  • Softly broken A4 symmetry for nearly degenerate neutrino masses 
    Ma E.; Rajasekaran G. (American Physical Society, 2001)
    The leptonic Higgs doublet model of neutrino masses is implemented with an A4 discrete symmetry (the even permutation of four objects or equivalently the symmetry of the tetrahedron) which has four irreducible representations: ...
  • Light unstable sterile neutrino 
    Ma E.; Rajasekaran G. (American Physical Society, 2001)
    The three massless active (doublet) neutrinos may mix with two heavy and one light sterile (singlet) neutrino so that the induced masses and mixings among the former are able to explain the present data on atmospheric and ...
  • An algebra for ordered particles 
    Mishra A.K.; Rajasekaran G. (1995)
    We construct an algebra of creation and destruction operators for a system whose multiparticle states have the property that the permutation of coordinates is forbidden. Although this "null statistics" can be related to a ...
  • Supersymmetric model of the muon anomalous magnetic moment and neutrino masses 
    Adhikari R.; Ma E.; Rajasekaran G. (2002)
    We propose the novel lepton-number relationship Lτ=Le + Lμ, which is uniquely realized by the interaction (ν̂eμ̂ - êμ̂μ in supersymmetry and may contribute to the muon anomalous magnetic moment. Neutrino masses (with ...
  • e+e-→γ+2 jets as a test of quark charges 
    HE X.G.; Pakvasa S.; Rajasekaran G.; Rindani S.D. (1987)
    It is shown that angular distribution in e+e-→γ+2 jets can serve as a possible test of quark charges but only above color threshold. © 1987.
  • Superstrings: Another view 
    Rajasekaran G.; Tuan S.F. (1987)
    [No abstract available]
  • 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 ...
  • Fock space representation of differential calculus on the noncommutative quantum space 
    Mishra A.K.; Rajasekaran G. (American Institute of Physics Inc., 1997)
    A complete Fock space representation of the covariant differential calculus on quantum space is constructed. The consistency criteria for the ensuing algebraic structure, mapping to the canonical fermions and bosons and ...
  • "Infinite statistics" and its two-parameter q-deformation 
    Mishra A.K.; Rajasekaran G. (1994)
    We generalize Greenberg's q-mutator algebra for infinite statistics to the most general form invariant under unitary transformations in the indices and study its consequences. Constraints on the parameter space arising ...
  • Rosenbluth scattering with Pauli moment for the electron 
    Basu R.; Murthy M.V.N.; Rajasekaran G. (1991)
    The authors show that the explicit inclusion of the effect of the anomalous magnetic moment for the electron in the electron-proton scattering cross section leads to contradictions with experimental data.
  • 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 ...
  • Three inequivalent mass-degenerate Majorana neutrinos and a scenario of their splitting for neutrino oscillations 
    Adhikari R.; Ma E.; Rajasekaran G. (2000)
    The mass matrix of three Majorana neutrinos of equal mass is not necessarily proportional to the identity matrix, but expressible in terms of two angles and one phase. We discuss how such a mass matrix may be stable or ...
  • Light sterile neutrinos from large extra dimensions 
    Ma E.; Rajasekaran G.; Sarkar U. (2000)
    An experimentally verifiable Higgs-triplet model of neutrino masses from large extra dimensions was recently proposed. We extend it to accommodate a light sterile neutrino which also mixes with the three active 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 ...
  • 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. ...
  • Standard model, Higgs Boson and what next? 
    Rajasekaran G. (Indian Academy of Sciences, Bangalore, 2012)
    One hundred years of Fundamental Physics, starting with discoveries such as radioactivity and electron, have culminated in a theory which is called the Standard Model of High Energy Physics. This theory is now known to be ...
