    Rajasekaran G. (1993)
  • HEP research in the Indian context - Reply 
    Rajasekaran G.; Ramachandran R. (Current Science Association, 1997)
  • Stable or Unstable Light Dark Matter 
    Ma E.; Murthy M.V.N.; Rajasekaran G. (arXiv, 2015)
    We consider the case of light dark matter (∼10 GeV). We discuss a simple Z2 model of scalar self-interacting dark matter, as well as a related model of unstable long-lived dark matter which can explain the anomalous Kolar ...
  • Electroweak Symmetry 
    Rajasekaran G. (Current Science Association, 1990)
  • Quantum interference effects in a five-dimensional Kaluza-Klein theory 
    Parthasarathy R.; Vasudevan R.; Rajasekaran G. (IoP Publishing, 1986)
    A quantum interference effect due to the scalar field in the five-dimensional Kaluza-Klein theory is derived.
  • Perspectives in High Energy Physics 
    Rajasekaran G. (Indian Association for the Cultivation of Science (IACS), 1998)
    A broad survey of High Energy Physics (HEP) both within as well as beyond the Standard Model is presented emphasizing the unsolved problems. Inspite of the spectacular success of the Standard Model, there is a serious ...
  • High energy physics in the 21st century - An overview 
    Rajasekaran G. (Current Science Association, 1996)
  • The Story of the Neutrino 
    Rajasekaran G. (arXiv, 2016)
    This is an elementary review of the history and physics of neutrinos. The story of the discovery of neutrino mass through neutrino oscillations is described in some detail. Experiments on solar neutrinos and atmospheric ...
  • Orthosupersymmetric Quantum Mechanics 
    Avinash Khare.; Mishra A.K.; Rajasekaran G. (World Scientific Publishing Co. Pte Ltd, 1993)
    We construct a new form of supersymmetric quantum mechanics named orthosupersymmetric quantum mechanics. We show that there are p orthosupercharges Qα (α= 1,2, …, p) which satisfy the algebra where H is the Hamiltonian. ...
  • A Test of the Quark Charges 
    Lakshmibala S.; HE X.G.; Pakvasa S.; Rajasekaran G. (World Scientific Publishing Co. Pte Ltd, 1986)
    We suggest the experimental study of as a test to distinguish between the fractionally charged quark (FCQ) model and the integrally charged quark (ICQ) model. We find that the strong dip in cross section at cos θ=−1/3 (θ ...
  • Parasupersymmetric Quantum Mechanics and its Infinite Order Limit 
    Avinash Khare.; Mishra A.K.; Rajasekaran G. (World Scientific Publishing Co. Pte Ltd, 1993)
    We propose an alternative formulation of parasupersymmetric quantum mechanics (PSQM) of arbitrary order which is simpler than the earlier versions and which leads to an explicit expression for the Hamiltonian in terms of ...
  • An Electroweak Factorization Theorem 
    Lakshmibala S.; Rajasekaran G. (World Scientific Publishing Co. Pte Ltd, 1989)
    We prove a factorization property relating the photon exchange, the Z boson exchange and the electroweak interference terms of the differential cross-section for the process fermion+ antifermion→bosons occurring through ...
  • Mass Shifts for the Weak Bosons in the Integrallly Charged Quark Model 
    Deshpande N.G.; Rajasekaran G. (World Scientific Publishing Co. Pte Ltd, 1990)
    We show that the integrally charged quark model predicts an upward shift of W and Z masses by 3.3 and 3.7 GeV respectively, as compared to the fractionally charged quark model. When combined with radiative corrections and ...
  • COMPLEX Q-MUTATOR ALGEBRA AND FRACTIONAL STATISTICS 
    Mishra A.K.; Rajasekaran G. (World Scientific Publishing Co. Pte Ltd, 1994)
    We construct a q-deformed algebra of creation and destruction operators with ordered indices in which the deformation parameter is complex. Its consequences are studied and its relation to “fractional” statistics is pointed out.
  • IS THERE A FUTURE FOR HIGH-ENERGY PHYSICS 
    Rajasekaran G. (Current Science Association, 1995)
  • Scientists against nuclear weapons 
    Rajasekaran G. (Current Science Association, 1998)
  • Algebra for Fermions with a new Exclusion-Principle 
    Mishra A.K.; Rajasekaran G. (Indian Academy of Sciences, 1991)
    We construct the algebra of the creation and destruction operators for spin 1/2 particles obeying a new exclusion principle which is “more exclusive” than Pauli’s exclusion principle: an orbital state shall not contain ...
  • Discussion on a possible neutrino detector located in India 
    Murthy M.V.N.; Yajnik U.A.; Balaji K.R.S.; Bhattacharyya G.; Dighe A.; Dugad S.; Dass N.D.H.; Kabir P.K.; Kar K.; Indumathi D.; Learned J.G.; Majumdar D.; Mondal N.K.; Murthy M.V.N.; Nayak S.N.; Pakvasa S.; Raychaudhuri A.; Raghavan R.S.; Rajasekaran G.; Ramachandran R.; Ray A.K.; Rindani S.; Sharatchandra H.S.; Sinha R.; Sinha N.; Umasankar S.; Yajnik U.A. (Indian Academy of Sciences, Bangalore, 2000)
    We have identified some important and worthwhile physics opportunities with a possible neutrino detector located in India. Particular emphasis is placed on the geographical advantage with a stress on the complimentary ...
  • Corrigendum: Anomalous Kolar events revisited: Dark matter? 
    Murthy M.V.N.; Rajasekaran G. (Indian Academy of Sciences, Bangalore, 2017)
    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 5–10 GeV, is pointed out.
  • Hierarchical four-neutrino oscillations with a decay option 
    Ma E.; Rajasekaran G.; Stancu I. (American Physical Society, 2000)
    We present a new and novel synthesis of all existing neutrino data regarding the disappearance and appearance of νe and νμ.We assume four neutrinos: νe,νμ,ντ,as well as a heavier singlet neutrino νs of a few eV. The latter ...
