  • Quantum Field Theory for Orthofermions and Orthobosons 
    Mishra A.K.; Rajasekaran G. (American Institute of Physics, 2000)
    We construct the quantum field theory of particles obeying new kinds of quantum statistics, called orthofermi and orthobose statistics. For the orthofermions (orthobosons), the wave function is antisymmetric (symmetric) ...
  • Decimet baryons as "elementary particles" 
    Rajasekaran G. (1967)
    Models which regard the decimet B* as a composite of the octet baryons and octet pseudoscalar mesons usually give excessively large SU(3) violations for the B* because of the large mass differences within the baryon octet ...
  • Current commutator and CPT 
    Rajasekaran G. (1967)
    It is shown that Gupta's commutator theory of CP violation violates the CPT theorem and that the anticommutator form for the current-current interaction is necessitated by CPT invariance alone, irrespective of whether CP ...
  • λ Binding in hypernuclei by nonlocal interaction 
    Rajasekaran G.; Biswas S.N. (1961)
    The characteristics of the Λ-N interaction at low energy have been obtained assuming that the Λ-N potential is nonlocal but separable and similar to that suggested by Yamaguchi in the case of N-N potential. The unknown ...
  • Model calculation for the Y0*(1405) resonance state 
    Dalitz R.H.; Wong T.C.; Rajasekaran G. (1967)
    The Y0*(1405) resonance state is considered in terms of a multichannel potential arising from vector meson (V) exchange between the baryon octet (B) and the pseudoscalar meson octet (P). The interactions are assumed to ...
  • Does the electromagnetic current have an I=2 component? 
    Divakaran P.P.; Gupta V.; Rajasekaran G. (1968)
    The possibility that the electromagnetic current may have a part transforming like I=2, with C=-1, in addition to the usual I=0 and I=1 parts is considered. It is argued that there is no evidence at present to exclude such ...
  • Resonance poles and mass differences within unitary multiplets 
    Dalitz R.H.; Rajasekaran G. (1963)
    [No abstract available]
  • Scattering amplitudes on unphysical sheets and resonance poles 
    Rajasekaran G. (Società Italiana di Fisica, 1964)
    [No abstract available]
  • The binding of ΛΛ-hypernuclei 
    Dalitz R.H.; Rajasekaran G. (1964)
    The binding energy of the systems ΛΛBe10 and ΛΛHe6, considered as three-particle systems (Λ-Λ-nucleus), are calculated as function of the Λ-Λ potential strength by a variational procedure using a trial function of the form ...
  • Meson-baryon mass splittings and resonance multiplets in SU3 symmetry 
    Rajasekaran G. (1965)
    It is shown that in order that symmetry considerations be applicable to resonances occurring between the thresholds connected by the symmetry principle, the modulus of the momentum in any channel should be smaller or at ...
  • SU(3) symmetry breaking in semileptonic decays 
    Pandit L.K.; Rajasekaran G. (1969)
    The first-order SU(3) symmetry breaking in semi-leptonic decays is studied by use of the techniques of equal time commutators. The correction for the baryon axial-vector decay constants is related to that for the strong ...
  • Restrictions on Schwinger terms due to Lorentz covariance 
    Gupta V.; Rajasekaran G. (1969)
    We consider the commutation relations of the vector and axial-vector current densities. Assuming that the commutators of the time components are given (with no Schwinger terms) we derive conditions imposed by covariance ...
  • 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 ...
  • 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. ...
  • 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 ...
  • 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 ...
  • The recent single-tag two-photon experiments at petra and the issue of quark charges 
    Godbole R.M.; Pati J.C.; Rindani S.D.; Jayaraman T.; Rajasekaran G. (1984)
    The data of recent single-tag two-photon experiments indicating noticeable excess in (Rγγ)jet over fractionally charged quark-parton model-predictions is studied from the point of view of its implications on the gauge ...
  • Direct photon production in e+e- collisions 
    Jayaraman T.; Rajasekaran G.; Rindani S.D. (1985)
    We study the process e+e-+X as a possible test to distinguish between fractionally-charged-quark models and gauged integer-charged-quark models. We find that charge-asymmetry measurement in this process would not distinguish ...
