  • 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 ...
  • 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 ...
  • 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) ...

  • 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 ...
  • Neutral currents in left-right symmetric gauge models 
    Bajaj J.K.; Rajasekaran G. (Indian Academy of Sciences, Bangalore, 1979)
    We analyse all the neutral-current phenomena following from the general class of gauge models based on the group SU(2)L ⊗ SU(2)R ⊗ U(1). It is found that the neutral-current couplings in these models bear a remarkable ...
  • 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 ...
  • 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 ...
  • 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 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 ...
  • 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) ...
  • 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 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 ...
  • 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 ...
  • Do the PETRA two-photon jet experiments rule out integrally charged quarks? 
    Jayaraman T.; Rajasekaran G.; Rindani S.D. (1982)
    The data on two-jet production in the PETRA single-tag two-photon experiments have been analyzed in the integer-charge quark model based on a spontaneously broken SU(3) colour gauge theory. The results show that the model ...
