"Mass Without Mass" and Nuclear Matter

Les politiques formalisées de préven- tion sont moins développées dans les petites unités [3] : ainsi, dans les petits établissements, il n’existe pas de protection collective

In this talk we present a description of nuclear binding in a chiral approach based on the existence of a chiral invariant scalar field associated with the generation of the

With confinement the value of the scalar coupling constant is reduced with respect to the linear sigma model or additive NJL model (g σ = M N /F π = 10) and the mass evolution is

It turns out that our question concerning the role of the pion cloud in the restoration of chiral symmetry in dense matter cannot be given in a model independent way.. (3) The

For sufficiently large coupling λ, parity symmetry is broken spontaneously at T = 0, and it becomes restored at high temperature by a second order phase transition.. The order

Secondly when we introduce confinement, i.e, when we go beyond NJL, the evolution of the nucleon mass with density, also depends on the nucleon structure through the value of

In fitting nuclear binding energies with the extended LDM formula (4), special care has to be taken with the treatment of T = 0 pairing effects (or Wigner energy)— with an
