  • Anomalous Kolar events revisited: Dark matter? 
    Murthy M.V.N.; Rajasekaran G. (Indian Academy of Sciences, Bangalore, 2014)
    The possibility of the unexplained Kolar events, recorded in the 1970s and 1980s, being due to the decays of dark matter particles of mass in the range of 510 GeV, is pointed out. © Indian Academy of Sciences.
  • Murray Gell-Mann (1929-2019) and the Story of Strong Interactions 
    Rajasekaran G. (Indian Academy of Sciences, Bangalore, 2019)
    Murray Gell-Mann, who passed away at the age of 90 years was a giant of modern particle physics. His most well-known contribution is the proposal that protons and neutrons are not indivisible but are made up of smaller ...
  • Manpower for fundamental physics experiments 
    Rajasekaran G. (2012)
    [No abstract available]
  • 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 ...
  • Möller and Bhabha scattering in the noncommutative standard model 
    Das P.K.; Deshpande N.G.; Rajasekaran G. (2008)
    We study the Möller and Bhabha scattering in the noncommutative extension of the standard model using the Seiberg-Witten maps of this to first order of the noncommutative parameter θμν. We look at the angular distribution ...
  • A crisis in fundamental physics 
    Rajasekaran G. (Indian Academy of Sciences, Bangalore, 2016)
    [No abstract available]
  • Predictions from high scale mixing unification hypothesis 
    Abbas G.; Gupta S.; Rajasekaran G.; Srivastava R. (American Physical Society, 2014)
    We investigate the renormalization group evolution of masses and mixing angles of Majorana neutrinos under the "high scale mixing unification" hypothesis. Assuming the unification of quark-lepton mixing angles at a high ...
  • Group velocity of neutrino waves 
    Indumathi D.; Kaul R.K.; Murthy M.V.N.; Rajasekaran G. (2012)
    We follow up on the analysis of Mecozzi and Bellini (arXiv:1110.1253v1) where they showed, in principle, the possibility of superluminal propagation of neutrinos, as indicated by the recent OPERA result. We refine the ...
  • Observing the dark scalar doublet and its impact on the standard-model Higgs boson at colliders 
    Cao Q.-H.; Ma E.; Rajasekaran G. (2007)
    If the standard model of particle interactions is extended to include a second scalar doublet [H+,(H0+iA0)/2], which is odd under an unbroken Z2 discrete symmetry, it may be called the dark scalar doublet, because its ...
  • TeV scale implications of non commutative space time in laboratory frame with polarized beams 
    Garg S.K.; Shreecharan T.; Das P.K.; Deshpande N.G.; Rajasekaran G. (Springer Verlag, 2011)
    We analyze e+e- → γγ, e -γ →γγ → e+e- processes within the Seiberg-Witten expanded noncommutative scenario using polarized beams. With unpolarized beams the leading order effects of non commutativity starts from second ...
  • Fermi and the theory of weak interactions 
    Rajasekaran G. (Indian Academy of Sciences, Bangalore, 2014)
    The history of weak interactions starting with Fermi's creation of the beta decay theory and culminating in its modern avatar in the form of the electroweak gauge theory is described. Discoveries of parity violation, ...
  • Keynote address: High energy physics in 2014 and its future 
    Rajasekaran G. (Indian Academy of Sciences, Bangalore, 2016)
    After a brief history, we focus on the present status of HEP and its possible future. Ideas to ensure a healthy growth of HEP in India are discussed. This involves a few major experimental projects in fundamental physics. ...
  • High scale mixing relations as a natural explanation for large neutrino mixing 
    Abbas G.; Abyaneh M.Z.; Biswas A.; Gupta S.; Patra M.; Rajasekaran G.; Srivastava R. (World Scientific Publishing Co. Pte Ltd, 2016)
    The origin of small mixing among the quarks and a large mixing among the neutrinos has been an open question in particle physics. In order to answer this question, we postulate general relations among the quarks and the ...
  • Was dark matter detected in India 40 years ago? 
    Rajasekaran G. (Indian Academy of Sciences, Bangalore, 2016)
    This paper is based on a paper written byMV NMurthy and G Rajasekaran, Pramana- J. Phys. 82, L609 (2014); arXiv:1305.2715. The possibility of the unexplained Kolar events, recorded in the 1970s and 1980s, being due to the ...
  • High scale mixing unification for Dirac neutrinos 
    Abbas G.; Gupta S.; Rajasekaran G.; Srivastava R. (American Physical Society, 2015)
    Starting with the high scale mixing unification hypothesis, we investigate the renormalization-group evolution of mixing parameters and masses for Dirac-type neutrinos. Following this hypothesis, the Pontecorvo-Maki-Naka ...
  • Cobimaximal neutrino mixing from A4 and its possible deviation 
    Ma E.; Rajasekaran G. (Institute of Physics Publishing, 2017)
    It has recently been shown that the phenomenologically successful pattern of cobimaximal neutrino mixing (θ13 ≠ 0, θ23 = π/4, and δCP = ±π/2) may be achieved in the context of the non-Abelian discrete symmetry A4, if the ...
