Showing papers in "Nuclear Physics in 1984"

TL;DR: In this paper, the authors present an investigation of the massless, two-dimentional, interacting field theories and their invariance under an infinite-dimensional group of conformal transformations.

TL;DR: In this article, the anomalous dimensions of the Wess-Zumino fields are found exactly, and the multipoint correlation functions are shown to satisfy linear differential equations, in particular, Witten's non-abelean bosonisation rules are proven.

TL;DR: In this paper, the consequences of an effective lagrangian for quarks, gluons and goldstone bosons in the region between the chiral symmetry breaking and confinement scales were studied.

TL;DR: In this paper, the cosmological constraints on supersymmetric theories with a new stable particle were considered and bounds on the parameters in the lagrangian which govern its mass and couplings were derived.

TL;DR: In this paper, a renormalization group equation for a four-dimensional λo4 theory with a momentum cutoff was derived, and the cutoff dependence of the effective lagrangian was analyzed.

TL;DR: Based on the conformal algebra approach, a general technique for the calculation of multipoint correlation functions in 2D statistical models at the critical point is given in this article, where particular conformal operator algebras are found for operators of the 2D q-component Potts model.

TL;DR: For the Q -state Potts model, the authors showed that η = 2 (3v − 1), and for the O( N ) model (−2 ⩽ N⩽ 2), η was shown to be 2 (2v−1) (4v−2).

TL;DR: In this paper, the twisted chiral multiplet is used to formulate supersymmetric nonlinear σ-models with N = 2,4 extended supersymmetry, which fall outside the classification given by Alvarez-Gaume and Freedman.

TL;DR: In this article, the massless limit of supersymmetric QCD with N flavors and N colors is analyzed in detail, and it is shown that it indeed appears, thus violating the non-renormalization theorems.

TL;DR: In this paper, a new model for hadronic jet fragmentation in hard processes is presented based on a QCD parton branching mechanism with correct treatment of leading collinear and infra-red singularities (i.e. including soft gluon interference).

TL;DR: In this paper, the Hartree-Fock-Bogolyubov theory of nuclei in the coordinate representation is considered and the HFB equation for the Skyrme effective interaction is solved.

TL;DR: In this paper, the general coupling of nN = 2 Maxwell super-multiplets to N = 2 supergravity in five spacetime dimensions was constructed. But the authors only considered the case that the scalar field manifold is symmetric.

TL;DR: In this paper, the phenomenology of lepton-number violation is analyzed in low-energy models in which R parity is explicitly broken by superrenormalizable operators, and the photino is able to decay, avoiding a stringent cosmological lower bound.

TL;DR: In this article, the transformation laws of the component fields and the equations of motion are derived and shown to be consistent at the full non-linear level using superspace techniques and exploiting the fact that the scalars belong to the coset space SU(1, 1)/U(1).

TL;DR: In this article, the covariant forms for both the currents and the anomalies for general gauge theories in even-dimensional space-time were constructed and the results were then extended to determine the structure of gravitational anomalies.

TL;DR: In this article, it was shown that in a simple minisuperspace model this boundary condition leads to a wave function which can be interpreted as a superposition of quantum states which are peaked around a family of classical solutions of the field equations.

TL;DR: In this paper, the general couplings of vector multiplets to N = 2 supergravity were investigated and the possibility of generalized duality invariance of the bosonic field equations was investigated.

TL;DR: In this article, the two-loop β-functions for the Yukawa couplings of the Higgs doublet in the minimal QCD-electroweak theory based on SU(3) × SU(2) × U(1).

TL;DR: This version of A = 9 differs from the published version in that it has corrected some errors discovered after the article went to press and reference key numbers have been changed to the NNDC/TUNL format.

TL;DR: In this paper, the authors consider cosmologies having an inflationary period during which the Robertson-Walker scale factor is an arbitrary function of time satisfying R > 0 (not necessarily an exponential).

TL;DR: In this paper, a new Monte Carlo simulation scheme for jet evolution in perturative QCD is presented, which takes into account the results of recent analyses of soft-gluon interference.

TL;DR: In this paper, it was shown that vector-like global symmetries (like isospin or baryon number) are not spontaneously broken in vectorlike gauge theories with θ = 0 (like QCD), and massless bound states do not form from massive constituents.

TL;DR: In this paper, the two-loop β-functions for the scalar quartic couplings are computed in a general renormalizable quantum field theory with scalar, spin-1 2, and (vector) gauge fields associated with a general gauge group G, using dimensional regularization and modified minimal subtraction (−MS).

TL;DR: In this paper, the authors constructed locally supersymmetric GUTs in which radiative corrections determine all the mass scales which are hierarchically smaller than the Planck mass: m 3 2 = O (m W ) = exp ( − O (1) α t )m p, etc.

TL;DR: In this article, the renormalization effects of SU(3)×SU(2)×U(1) models coupled to supergravity were studied at the one-loop level.

TL;DR: In this paper, a generalization of the dimensional reduction of supersymmetric string theories is introduced, which leads to spontaneous breaking of the supersymmetry, which has non-trivial consequences for the quantization and dynamics of the theory.

TL;DR: In this paper, a system of spins with quenched random mfimte ranged p-spin interactions for p -* co is studied and the model is solved exactly either by a direct mlcrocanomcal argument, or through the introduction of rephcas and Pansl's ultrametnc ansatz for symmetry breaking, or by means of TAP mean field equat,ons.

TL;DR: In this article, the authors investigated the possibility that the most essential nonperturbative gauge field configurations in QCD are of an instanton-anti-instanton type and showed that the repulsion of instantons leads to the stabilization of the pseudoparticle liquid at distances being a factor of ∼ 3 larger than their average sizes.

TL;DR: In this article, a modified Hamiltonian equation of motion for density matrices was proposed to interpret upper bounds on the violation of quantum mechanics in different... phenomenological situations.

TL;DR: In this article, a microscopic description based on the density-dependent Hartree-Fock-Bogolyubov approach with several kinds of constraints is used to extract the characteristic features of the collective dynamics of the fission process at low energy.
