“…Thus they affect the nuclear symmetry energy, which arises when there are unequal numbers of neutrons and protons. The construction of a renormalizable lagrangian containing charged, massive vector fields is somewhat complicated and is discussed at length in Abers and Lee [Ab73]; applications to the present model can be found in [Se86]. For our purposes, we require only the classical contributions from these fields, and in this case, the lagrangian simplifies considerably.…”

Quantum hadrodynamics (QHD) is a framework for describing the nuclear many-body problem as a relativistic system of baryons and mesons. Motivation is given for the utility of such an approach and for the importance of basing it on a local, Lorentz-invariant lagrangian density. Calculations of nuclear matter and finite nuclei in both renormalizable and nonrenormalizable, effective QHD models are discussed. Connections are made between the effective and renormalizable models, as well as between relativistic mean-field theory and more sophisticated treatments. Recent work in QHD involving nuclear structure, electroweak interactions in nuclei, relativistic transport theory, nuclear matter under extreme conditions, and the evaluation of loop diagrams is reviewed.

Unité associée au CNRS D0 280. Abstract:The Standard Model of electroweak interactions is shown to include a gauge theory for the observed scalar and pseudoscalar mesons. This is done by exploiting the consequences of embedding the SU (2) L × U (1) group into the chiral group of strong interactions and by considering explicitly the Higgs boson and its three companions inside the standard scalar 4-plet as composite.No extra scale of interaction is needed. Quantizing by the Feynman path integral reveals how, in the 'Nambu Jona-Lasinio approximation', the quarks and the Higgs boson become unobservable, and the theory anomaly-free. Nevertheless, the 'anomalous' couplings of the pseudoscalar mesons to gauge fields spring again from the constraints associated with their compositeness itself. This work is the complement of ref.[1], where the leptonic sector was shown to be compatible with a purely vectorial theory and, consequently, to be also anomaly-free. The bond between quarks and leptons loosens. 11.15.Ex, 11.30.Rd, 11.40.Ha, 12.15.Ff, 12.38.Cy, 12.38.Lg, 12.60.Nz, 12.60.Rc, 13.40.Hq, 14.80.Bn, 14.80 PACS:

“…Finally, in 1976 it was suggested that all fundamental interactions could be uniquely described in the context of a supergravity theory (Freedman et al 1976, Deser andZumino 1976). For a detailed discussion of the present status of elementary particle theory one can consult many excellent books and reviews (Abers and Lee 1973, Taylor 1976, Fayet and Ferrara 1977, Langacker 1981, van Nieuwenhuizen 1981, Okun' 1982.…”

According to the inflationary universe scenario the universe in the very early stages of its evolution was exponentially expanding in the unstable vacuum-like state. At the end of the exponential expansion (inflation) the energy of the unstable vacuum (of a classical scalar field) transforms into the energy of hot dense matter, and the subsequent evolution of the universe is described by the usual hot universe theory.Recently it was realised that the exponential expansion during the very early stages of evolution of the universe naturally occurs in a wide class of realistic theories of elementary particles. The inflationary universe scenario makes it possible to obtain a simple solution to many longstanding cosmological problems and leads to a crucial modification of the standard point of view of the large-scale structure of the universe.
