  • Classical solutions of a model of quark confinement 
    Rajasekaran G.; Srinivasan V. (Indian Academy of Sciences, Bangalore, 1978)
    We find the classical solutions of a model of quark confinement defined by the vanishing of colour currents. Both plane-wave type of solutions extending all over space as well as string-type of solutions confined to ...
  • Spin dependence of the charged-gluon contribution in deep-inelastic scattering 
    Mani H.S.; Rajasekaran G.; Rindani S.D. (1980)
    In the integer-charge quark model, it is found that because of the photon-gluon mixing, only the zero-helicity gluons couple to deep-inelastic probes. As a particular consequences, gluons do not contribute to the (longitudinal) ...
  • Contribution of gluons and coloured Higgs bosons to e+-e- annihilation into three jets 
    Lakshmibala S.; Rajasekaran G.; Rindani S.D. (1981)
    Three-jet thrust and angular distributions in e+e- annihilation are calculated in the integer-charge quark model. The complete contributions of gluons and Higgs scalars are presented. Deviations from QCD results are in ...
  • Model-independent analysis of the neutral-current interaction in the inclusive neutrino reactions 
    Rajasekaran G.; Sarma K.V.L. (Indian Academy of Sciences, Bangalore, 1974)
    On the basis of some general assumptions on the deep inelastic structure functions, such as scaling and chiral symmetry we determine the values of {(HV3)2+(HA3)2}+η{(HV0)2+(HA0)2} and HV3 HA3+ηHV0 HA0 where HV3,0 and HA3,0 ...
  • Interpretation of the new particle of the cosmic ray neutrino experiment 
    Rajasekaran G.; Sarma K.V.L. (Indian Academy of Sciences, Bangalore, 1975)
    In order to reconcile the life time of the new particle observed in the cosmic ray neutrino experiment with its production rate, it is proposed that the particle has a new quantum number (κ) which may be assigned to leptons ...
  • Theoretical implications of the resonance anomalies in the e+-e- system 
    Pakvasa S.; Rajasekaran G.; Tuan S.F. (1975)
    The phenomenological properties of the recent resonance anomalies at 3.1 GeV and 3.7 GeV in e+-e- systems are confronted in a fairly systematic way with models presently known to us. These include charm-related models, ...
  • General space-time structure of the neutral-current interactions 
    Pakvasa S.; Rajasekaran G. (1975)
    We present a general analysis of the neutral-current inclusive cross section taking into account all the covariants (scalar, pseudoscalar, tensor, vector, and axial-vector) in the interaction. We derive the model-independent ...
  • Effective-dipole form-factors for the Kl3-decay 
    Chhajlany S.C.; Pandit L.K.; Rajasekaran G. (1971)
    To describe the latest experimental situation on the Kl3 decays (which shows large λ+≈0.07 along with a ξ≈-0.9), effective-dipole form-factors, satisfying exact results of first order breaking of the chiral SU3 ⊗ SU3 ...
  • Scaling and the asymptotic behaviour of form factors 
    Divakaran P.P.; Rajasekaran G. (1973)
    It is shown that if all spin averaged matrix elements for the production of an arbitrary hadronic state |i> by the absorption of a virtual photon of momentum q on a proton vanish as q2→∞ (space-like), and if this ...
  • Bounds on the coupling constants of the neutral current 
    Rajasekaran G.; Sarma K.V.L. (1975)
    We derived bounds on the coupling constants which characterize the strengths of the various pieces of the weak hadronic neutral current using isospin invariance of strong interactions alone. For the numerical evaluation ...
  • Erratum: Fixed pole in the virtual compton amplitude A2 
    Rajaraman R.; Rajasekaran G. (1971)
    [No abstract available]
  • The electroweak mixing angle in unified gauge theories 
    Bajaj J.K.; Rajasekaran G. (Indian Academy of Sciences, Bangalore, 1980)
    We study in detail the factors that influence the unification relations among the coupling parameters of strong and electroweak interactions. We find that the factor that decides the unification relations in a theory is ...
  • Inelastic electron-proton scattering and a sum rule for the Schwinger term 
    Gupta V.; Rajasekaran G. (1971)
    It is shown that the form of the one-particle expectation value of the Schwinger term in the equal-time commutator of the electromagnetic current and change densities is determined by relativistic covariance. This allows ...
  • Axial-vector Kl4-decay form factors based on current algebra 
    Chhajlany S.C.; Pandit L.K.; Rajasekaran G. (1970)
    The axial-vector Kl4-decay form factors given by current algebra have been reevaluated using the vector Kl3-decay form factors and the ratio fKfπ, obtained on the basis of broken chiral SU3 SU3 and SU3 symmetries. It is ...
  • The leptonic K-decays with broken SU(3) ⊗ SU(3) and SU(3) and violation of μ- e universality 
    Chhajlany S.C.; Pandit L.K.; Rajasekaran G. (1970)
    A phenomenological treatment of μ - e universality violation in the strangeness-changing decays is proposed to account for the existing discrepancies between the form factors and other decay parameters of the leptonic ...
  • On the electron-muon universality in strangeness-changing processes 
    Rajasekaran G.; Sarma K.V.L. (1970)
    It is suggested that the available data are consistent with the hypothesis that the electronic and the muonic weak currents have slightly different couplings to the strangeness-changing hadronic current. The consequences ...
  • Fixed pole in the virtual compton amplitude A2 
    Rajaraman R.; Rajasekaran G. (1971)
    We suggest here the presence of a J=0 fixed pole in the virtual Compton amplitude A2 with a residue linear in the photon mass q2 for all q2. The resultant sum rule is found to be consistent with the on-mass-shell (q2=0) ...
  • Sum rules from local current algebra 
    Gupta V.; Rajasekaran G. (1969)
    By combining the local current algebra with the commutation relations between the current densities and the Lorentz boost operator, we derive low-energy theorems as well as sum rules which involve neutrino and electron ...

  • The mass of the electron neutrino and electron capture in 163Ho 
    Yasumi S.; Rajasekaran G.; Ando M.; Ochiai F.; Ikeda H.; Ohta T.; Stefan P.M.; Maruyama M.; Hashimoto N.; Fujioka M.; Ishii K.; Shinozuka T.; Sera K.; Omori T.; Izawa G.; Yagi M.; Masumoto K.; Shima K. (1983)
    To determine the mass of the electron neutrino, electron capture in 163Ho was studied. From the intensity of M X-rays and the total number of 163Ho atoms in a source, as determined by the PIXE method, the partial M-capture ...
