  • Two Topics in Electroweak Physics: Radiative Corrections and Baryon Number Violation 
    Rajasekaran G. (World Scientific Publishing Co. Pte Ltd, 1992)
  • Integer-Charged Quark Model and Electron-Positron Annihilation into Three Jets 
    Rajasekaran G.; Rindani S.S. (Oxford University Press, 1982)
    The consequences of the integer-charge quark model in electron-positron annihilation into three jets are studied. To first order in αs, three-gluon jets also contribute, in addition to quark-antiquark-gluon jets. If the ...
  • 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 ...
  • Leptons and Quarks as Composites of Orthofermions 
    Rajasekaran G. (Allied Publishers, 1995)
  • Is Quantum Mechanics Forever ? 
    Rajasekaran G. (Tata Institute of Fundamental Research, 1989)
  • 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 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 ...
  • 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 ...
  • 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 ...
