  • 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. © ...
  • 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 ...
  • Fields with vanishing colour-currents 
    Rajasekaran G.; Srinivasan V.; Ram M.S.S. (Springer India, 1985)
    We consider spinor, scalar and vector fields with colour degrees of freedom and find the classical solutions when the constraint of vanishing colour currents is imposed. We find that there are no non-trivial c-number ...
  • The electroweak mixing angle in unified gauge theories-the renormalisation effects 
    Bajaj J.K.; Rajasekaran G. (Indian Academy of Sciences, Bangalore, 1980)
    A general analysis of the renormalisation corrections to the unification results for the coupling constants of strong and electroweak interactions is attempted. In particular, the effects of introducing an energy scale ...
  • Neutral current cross-sections for neutrinos on protons 
    Rajasekaran G.; Sarma K.V.L. (Indian Academy of Sciences, Bangalore, 1978)
    Defining the ratios rp =σ(vp →vx)/σ(vp →μ- x) and {Mathematical expression} we obtain the bounds 0.28 ≤rp ≤ 0.61 and {Mathematical expression} using only the parton model and the data of CDHS group with iron target. We ...
  • 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 ...
  • Radiative decays, photoproduction and total cross section of the ψ particles 
    Sarma K.V.L.; Rajasekaran G.; Pasupathy J. (Indian Academy of Sciences, Bangalore, 1976)
    It is pointed out that the coupling characterizing the ψ-γ vertex must change substantially between the limits, ψ on mass-shell which occurs in ψ→e+ e- and photon on mass-shell which is relevant in radiative decays like ...
  • 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 ...
  • Colour gluons and scaling in a unified gauge model 
    Rajasekaran G.; Roy P. (Indian Academy of Sciences, Bangalore, 1975)
    Deep inelastic weak and electromagnetic processes are considered within the parton framework taking the partons to be integrally charged quarks and coloured gluons. Despite the participation of the spin-one gluons in these ...
  • Two-photon production in pp and pp collisions 
    Jayaraman T.; Rajasekaran G.; Rindani S.D. (1986)
    We show that the process pp (pp)++X is a powerful test to distinguish between gauged integer-charged-quark models (ICQMs) and fractionally-charged- quark models (FCQMs). We study the ratio of the two-photon production cross ...
  • The possibility of two-gluon jets in electron-positron annihilation 
    Rajasekaran G.; Rindani S.S. (1979)
    The possibility of two-gluon jets in electron-positron annihilation is pointed out. Because of this gluon contribution, the overall angular distribution of the jets in the scaling limit is predicted to be 1 + 0.86cos2θ. © 1979.
  • 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 ...
  • 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 ...
  • 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 ...
