TL;DR: In this paper, a phenomenological Lagrangian is constructed to describe an interaction of the neutrino with itself and with other particles, based on the hypothesis that neutrinos are goldstone particles.

TL;DR: In this article, it is pointed out that there are several advantages in abstracting properties of hadrons and their currents from a Yang-Mills gauge model based on colored quarks and color octet gluons.

TL;DR: In this paper, the rates relative to the corresponding charged current processes are evaluated for events induced by neutral particles and producing hadrons, but no muon or electron, have been observed in the CERN neutrino experiment.

TL;DR: One possible event of the process ν − μ+ e − → v − μ + e − has been observed in this article, and the event is interpreted in terms of the Weinberg theory.

TL;DR: In this article, the imposition of unitarity bounds is shown to lead to a Yang-Mills structure in a wide class of theories involving vector mesons, where Scalar fields are needed and the unique unitary theory is of the Higgs type.

TL;DR: Several theoretically interesting forms of the nucleon EM form factor have been considered and found to provide quantitative descriptions of available data with as few as three adjustable parameters as discussed by the authors, but none of them can be used to provide a quantitative description of the available data.

TL;DR: The absolute scale of the cross-section was established by determination of the effective density of the colliding beans in their overlap region as mentioned in this paper, which was deduced by extrapolation of the elastic differential crosssection to the forward direction and by application of the optical theorem.

TL;DR: Experimental data on transfer reactions in the /sup 40/Ar + /sup 232/Th system are interpreted in terms of nuclear orbiting combined with dissipation of energy due to the friction forces as discussed by the authors.

TL;DR: The renormalization of the axial coupling constant in nuclei is related by PCAC to the exchange effects in the pionic vertex as mentioned in this paper, and the analogy between this problem and that of an electric dipole inside a dielectric medium is pointed out.

TL;DR: In this article, the authors present the first results of a measurement of the total cross-section σ T in proton-proton collisions at equivalent laboratory momenta between 291 and 1480 GeV/c at the CERN Intersecting Storage Rings (ISR).

TL;DR: In this article, the interaction between two heavy nuclei is discussed within a simple, classical model, which allows quantitative predictions for interaction and fusion thresholds, and for limiting angular momenta in surface and fusion reactions.

TL;DR: In this article, the invariant cross-sections for the inclusive reaction p + p → π o + anything were presented for the CERN ISR at five centre-of-mass energies (√ s = 23.5, 30.6, 44.8, 52.7 and 62.4 GeV).

TL;DR: In this article, a duality relation between vector meson formation and scaling ( 1 s ) behavior in the total cross section σ had ( s ) for e + + e − → hadrons was conjectured.

TL;DR: In this paper, two-photon processes in colliding e ± e − beam reactions were studied, with the aim of testing the parton model, and it was shown that parton contributions dominate in certain well defined kinematical limits, and provide an essential difference between photonic and hadronic processes.

TL;DR: In this paper, the v and v nucleon total cross-sections have been determined as a function of energy using a sample of 2500 v and 950 v event, compared with predictions of scaling and charge symmetry hypotheses.

TL;DR: The Dirac equation for a relativistic particle (electron) in the field of two Coulomb centres Z1 and Z2 has been solved as mentioned in this paper, and the systems BrBr, IAu, UU are shown as examples.

TL;DR: In this article, the energy due to zero point fluctuations of the dual string is calculated and shown to be divergent, and it is shown that this leads to the well-known relation relating the mass squared of the lowest state to the number of dimensions space-time.

TL;DR: In this paper, the authors used the "incoherent droplet model" to explain the fragmentation of 16O during high energy collision with a Be target, where the fragments have a universal iso tropic Gaussian momentum distribution, independent to the masses of the fragments.

TL;DR: The detection of Coulomb scattering and its interference with nuclear scattering leads to the determination of the real part of the nuclear amplitude and of the total proton-proton cross section by the optical theorem.

TL;DR: In this paper, the pion nucleon coupling constant and s-wave scattering length were obtained from fixed t dispersion relations, using low energy πN angular distribution and total cross section data.

TL;DR: The identical quanta correlations give an information on the spatial and time structure of the production reactions as discussed by the authors, and their dependence on the multiplicity and average particle energy is estimated and compared with available data.

TL;DR: In this article, a non-relativistic three-triplet model with a simple two-body interaction is shown to bind only q q and q q states. But it is not shown that three triplets and unobserved charmed states are crucial in preventing binding of 4q q and 2 q q systems.

TL;DR: In this paper, the ratio of the deuteron to proton electric form factors was measured for low q, and the rms radius of the structure factor was found to be 1.9635 ± 0.0045 fm, yielding an rms charge radius of 2.095 − 0.006 fm.

TL;DR: In this paper, the microscopic theory of nuclear friction in heavy ion scattering is developed and a relation of the friction tensor to the imaginary optical model potential is given, which seems to be very useful to get order of magnitude estimates of both quantities.

TL;DR: In this article, the existence of a generalized ergosphere in the Reissner Nordstrom geometry and an explicit formula to determine its range is given. But this formula is not applicable to the case of the Kerr solution.

TL;DR: In this paper, a simple model of hadron scattering from 20 to 5000 GeV is given based on the impact picture derived from quantum field theory. But the model is not suitable for high energy hadron-hadron elastic scattering.

TL;DR: Based on the particle-plus-rotor model, it was shown that a new coupling scheme should occur in nuclei under certain conditions as discussed by the authors, in which j is quantized along the direction of I rather than along the symmetry axis.

TL;DR: In this article, all charged particles of transverse momentum p T between 1.5 and 4.4 GeV/c at center of mass angles 90° and 59.4° from p-p-collisions with √ s = 44 and 53 GeV has been measured.

TL;DR: In this paper, the elastic and inelastic scattering of 1.04 GeV proton by 12 C, 58 Ni and 208 Pb with an energy resolution of the order of 100 keV is presented.
