  • General relations among observables in neutral-current phenomena mediated by one or two Z bosons 
    Parida M.K.; Rajasekaran G. (Indian Academy of Sciences, Bangalore, 1979)
    If μ-e universality is assumed, there are 17 neutral-current parameters of current experimental interest, including the parity-violating nuclear force sector. We deduce the general relations among these parameters implied ...
  • Empirical test for composite hadrons 
    Rajasekaran G. (1972)
    We describe an empirical test to distinguish hadrons which are composites in the low-threshold channels from those which can be understood only from a more global point of view. This test is based on the existence of a ...
  • General bounds on the isovector coupling constants of the weak neutral current 
    Rajasekaran G.; Sarma K.V.L. (Indian Academy of Sciences, Bangalore, 1976)
    We show that experimental data on inclusive neutrino reactions can be used to obtain general bounds on the coupling constants of the isovector part of the hadronic weak neutral current provided this isovector current is ...
  • 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 ...
  • Contribution of coloured Higgs bosons to e+e- annihilation into two jets 
    Rajasekaran G.; Rindani S.D. (1981)
    We examine the effect of the coloured Higgs bosons (of the integer-charge quark model) on electron-positron annihilation into two jets. The overall angular distribution of the quark + gluon + Higgs jets in the scaling limit ...
  • Comments on "is bound charm found?" 
    Pasupathy J.; Rajasekaran G. (1975)
    The inadequacy of the Ansatz proposed by De Rújula and Glashow for explaining the meson masses is discussed. The importance of fixing the spin-parity of the abnormal parity states E(1420) and D(1285) for the possible success ...
  • Divergences of the higher-order corrections to μ decay in Weinberg's gauge theory 
    Rajasekaran G. (1972)
    The leading (quadratic) divergences in the second-order weak and electromagnetic corrections to μ decay are calculated in Weinberg's gauge theory and it is shown that, after renormalization, these divergences cancel. © ...
  • Electron-positron annihilation into three jets in the integer-charge quark model 
    Rajasekaran G.; Rindani S.D. (1980)
    We discuss e+e− → 3 jets in the integer-charge qaurk model. In the lowest non-trivial order, ignoring coloured Higgs scalars, we find that three-gluon jets would be observable at present PETRA energies if the gluon mass ...
  • Constraints on the parameters of the left-right symmetric gauge models 
    Bajaj J.K.; Rajasekaran G. (1980)
    We find an important constraint on the parameters of the general four-parameter left-right symmetric model. The constraint links the v-hadron sector of the model with the parity-violation sector. Using this constraint along ...
  • Analysis of the neutral-current interaction in the inclusive neutrino reactions 
    Rajasekaran G.; Sarma K.V.L. (Indian Academy of Sciences, Bangalore, 1974)
    We attempt a general phenomenological analysis of the neutral weak current in the inclusive neutrino reactions using the parton model as a tool. From the recently reported data on these processes we determine the strength ...
  • Generation of gluons from quark confinement 
    Rajasekaran G.; Srinivasan V. (Indian Academy of Sciences, Bangalore, 1978)
    We study a model of quark confinement defined by the vanishing of colour currents. The model is shown to be equivalent to quantum chromodynamics and this equivalence is interpreted as due to the compositeness of the colour ...
  • Color gluon excitation at fermilab 
    Rajasekaran G.; Roy P. (1976)
    In unified gauge theories with color (excitable by lepton probes), color effects become manifest in the asymptotic region through gluon terms. Several new results pertaining to these are derived and quantitatively discussed. ...
  • Renormalizable theories from nonrenormalizable interactions 
    Rajasekaran G.; Srinivasan V. (Indian Academy of Sciences, Bangalore, 1977)
    By using Kikkawa's method the equivalence of the nonrenormalizable pair interaction {Mathematical expression} to a renormalizable theory is proved. Equivalence relationships between a few other nonrenormalizable and ...
  • A note on the annihilation of polarised e+e- beams into jets in the broken colour gauge theory 
    Lakshmibala S.; Rajasekaran G.; Rindani S.D. (1982)
    The dependence of angular distribution on polarisation for the processes of transverse or longitudinally polarised e+e- beams annihilating into two or three jets has been got from very general considerations. It is seen ...
  • 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 ...
  • Non-renormalization of the weak vertex in gauge theories with integrally charged quarks 
    Rajasekaran G.; Sri Ram M.S. (Indian Academy of Sciences, Bangalore, 1982)
    We give current algebra arguments to show that to O(α) the colour octet vertices do not renormalize the effective weak vertex between colour singlet hadrons in models with broken colour symmetry. The result does not depend ...
  • Decays of W and Z in the broken-colour model 
    Lakshmibala S.; Rajasekaran G.; Rindani S.D. (Indian Academy of Sciences, Bangalore, 1985)
    The two-gluonic decay modes of W and Z in the broken colour model with integrally charged quarks are considered. The gluonic branching ratios are found to be 3% and 2·7% for W and Z respectively. The angular distributions ...
  • Erratum: Analysis of the neutral-current interaction in the inclusive neutrino reaction 
    Rajasekaran G.; Sarma K.V.L. (Indian Academy of Sciences, Bangalore, 1974)
    [No abstract available]
  • Effect of gluons on neutral-current interactions in deep inelastic neutrino scattering 
    Rajasekaran G.; Roy P. (Indian Academy of Sciences, Bangalore, 1975)
    The contribution of neutral spin-1 gluons to the deep inelastic neutral-current processes v(v)+N→v(v)+ hadrons is worked out in the parton model. Such a contribution violates Bjorken scaling strongly. © 1975 the Indian ...
