TL;DR: In this article, the authors find regular solutions of the four dimensional euclidean Yang-Mills equations and show that these solutions minimize locally the action integrals, which is finite in this case.

TL;DR: In this article, the high energy amplitude in the spontaneously broken Yang-Mills model within the leading logarithmic approximation was calculated, and it was shown that the vector meson is reggeised whereas the Pomeranchon is a fixed branch point located at the right hand from j = 1.

TL;DR: In this article, the general dynamical system with constraints is quantized, and the S-matrix is constructed in the most general class of gauges including relativistic ones, and a new type of additional diagrams arises securing unitarity of the theory: the fourfermion interaction of ghost fields.

TL;DR: In this paper, it is shown that due to interaction the regime of the asymmptotic freedom arises and the continuation to higher dimensions and the applications of the result are briefly discussed.

TL;DR: In this article, it is shown that infrared phenomena in the gauge theories are guided by certain classical solutions of the Yang-Mills equations, which can lead to a finite correlation length which stops infrared catastrophe.

TL;DR: In this article, the authors suggest that the observed exponential spectrum is connected to the existence of a different phase of the vacuum in which quarks are not confined, and that the exponential increasing spectrum is present in any system which undergoes a second order phase transition.

TL;DR: In this paper, it was shown that finite-length vortices in an SU(n) Nielsen-Olesen model require explicit introduction of monopoles, which are confined in multiples of n by the Meissner effect.

TL;DR: In this article, a minimal theory based on six quark flavors and six lepton flavors and on the group SU2 × U1 (presumably a subgroup of a larger gauge group) is presented.

TL;DR: In this article, the Yakubovsky four-body equations for the 0+state were solved in the boundstate region for the case of local central forces of the Yukawa type, using the Hilbert-Schmidt expansion.

TL;DR: In this article, the concept of determinant is generalized to superspace and the metric density superfields are defined, and an invariant action principle in curved superspace is constructed.

TL;DR: In this article, the authors interpreted the 10-dimensional space-time of the spinor dual model as the product of ordinary 4dimensional space time and a 6-dimensional compact domain, whose size is as yet unobserved.

TL;DR: The existence of a weakly-coupled scalar boson, recently proposed to explain the apparent discrepancy in X-rays from muonic atoms is shown to be inconsistent with the angular distribution measurements in low energy neutron-nucleus scattering.

TL;DR: In this paper, the Yang-Mills superfield is generalized to a local gauge invariance, which produces self-interactions in the field equations and automatically generates coupled Maxwell-Dirac, Einstein equations, etc.

TL;DR: In this paper, the 3 S 1 S mass separations of the bound quark-antiquark systems, arising from one-gluon exchange, in the charm color quartet scheme, are discussed for the ground mesons and their first radial excitations expecially in connection to leptonic decay rates.

TL;DR: In this article, it was suggested that quarks and leptons are composites of still more fundamental PRE-entities, i.e., the fundamental components of a PRE.

TL;DR: In this paper, the modifiedoscillator field with the inclusion of an ωJx term to describe the effects of nuclear rotation forms the basis for the calculation of microscopic energies.

TL;DR: In this paper, the parton model is shown to predict antishadowing phenomenon in deep inelastic scattering of electrons or neutrinos off a nucleus, and the sum rule is proposed according to which the integrated cross section foe electron-nucleus interaction is equal to the sum cross sections for electron nucleon interactions.

TL;DR: In this article, the equation of state for neutron matter at all temperatures is presented in a relativistic mean-field theory which describes known nuclear matter, and some limiting analytic forms of the EOS are given.

TL;DR: The role of colour and charm and heavy mirror fermions was explored in interpreting the J/ψ particles, the Kolar-mine events and the neutrino-antineutrino anomaly.

TL;DR: In this article, a second-order DWBA analysis was performed for the 124,130 Te(p, t) 122,128 Te reactions at E p = 51.9 MeV.

TL;DR: In this paper, a model of interacting scalar multiplets, where supersymmetry is spontaneously broken, generating a Goldstone spinor, is presented, where ordinary Goldstone bosons are replaced by scalar particles, massless at zeroth order.

TL;DR: In this paper, the authors presented experimental results on proton-proton elastic scattering at center-of-mass energies s =23 GeV and s =62 GeV using the Split Field Magnet detector at the CERN Intersecting Storage Rings.

TL;DR: In hypercharge exchange reactions (K−, π−) on light nuclei Λ particles with small recoil momentum have been produced as mentioned in this paper, and the observed hypernuclear states in Λ9Be, Λ12C and Λ16O have simple neutron-hole Λ-particle configurations.

TL;DR: In this article, the authors examined the possibility that nuclear-matter binding energy comes from the coupling of nucleons to a mean scalar field; vector fields are simulated by Yukawa potentials.

TL;DR: The relative suppression of the Φ is in qualitative accord with its coupling to nonstrange states as discussed by the authors, and no tendency is observed for the final states to contain strange particles in conjunction with Φ.

TL;DR: In this article, a suitable generalization of the Skyrme interaction is suggested to overcome these difficulties and the results of G o and G o are in disgreement with empirical values and lead to instability against spin collapse in several cases.

TL;DR: In this article, the cross sections and angular distributions of fragments emitted in heavy ion reactions are calculated on the basis of a diffusion mechanism associated with the mass (charge) asymmetry of a short-lived intermediate complex.

TL;DR: In this paper, the deformation energies at spins I ≲ 100 of 16 rare earth nuclei have been calculated including shell corrections obtained by a straightforward generalization of the Strutinsky method.

TL;DR: In this article, the two photon cascade decay of the 3.7 GeV resonance into 3.1 GeV has been observed in two nearly independent experiments and the clustering of the photon energies around 160 MeV and 420 MeV observed in the channel 3.5 → (3.1 → μ + μ − ) + γγ indicates the existence of at least one intermediate state with even charge conjugation at a mass around 3.52 GeV or 3.26 GeV.
