  • The discovery of Dirac equation and its impact on present-day Physics 
    Rajasekaran G. (Indian Academy of Sciences, Bangalore, 2003)
    The major events in the discovery of the Dirac equation and its interpretation are traced. The subsequent role it has played in the development of quantum field theory culminating in the Standard Model of present-day high ...
  • Can Y o ? (1405) be a bound state of three quarks? 
    Rajasekaran G. (Springer, 1969)
    Two approaches have been used so far to understand the observed hadron spectrum: a) to regard any observed hadron as a composite (bound or resonant) formed by forces between other observed hadrons, and b) to consider the ...
  • An Unified Treatment of Quantum Interference Effects 
    Parthasarathy R.; Rajasekaran G.; Vasudevan R. (Allied Publishers, 1995)
  • What is the next step after electroweak unification? 
    Rajasekaran G. (IIT Kanpur, 1985)
  • Large neutrino mixing angles for type-I see-saw mechanism in SO(100 GUT 
    Bipin.R.Desai.; Rajasekaran G.; Utpal Sarkar (arXiv, 2005)
    We consider the neutrino mixing angles in an SO(10) GUT with the usual Higgs structure in which neutrino masses are explained by the type-I see-saw mechanism. The Dirac-neutrino Yukawa matrix then has a structure similar ...
  • Generalized Fock Spaces and New Forms of Quantum Statistics 
    Rajasekaran G. (American Institute of Physics, 1995)
    The recent discoveries of new forms of quantum statistics require a close look at the under-lying Fock space structure. This exercise becomes all the more important in order to provide a general classification scheme for ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Dynamics in a noncommutative phase space 
    Malik R.P.; Mishra A.K.; Rajasekaran G. (World Scientific Publishing Co. Pte Ltd, 1998)
    Dynamics in a noncommutative phase space is considered. The noncommuting phase space is taken to be invariant under the quantum group GLq,p(2). The q-deformed differential calculus on the phase space is formulated and using ...
  • 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 ...
