The NJL model and strange quark matter
The stability of strange quark matter is studied within the Nambu JonaLasinio model with three different parameter sets. The model Lagrangian contains 4-fermion (with and without vector interaction) and 6-fermion terms; the minimum energy per baryon number as a function of the strangeness fraction of the system is compared to the masses of hyperons having the same strangeness fraction, and cohe...
متن کاملStrange quark matter attached to string cloud in general scalar tensor theory of gravitation
Bianchi type-VI0 space time with strange quark matter attached to string cloud in Nordtvedt [1] general scalar tensor theory of gravitation with the help of a special case proposed by Schwinger [2] is obtained. The field equations have been solved by using the anisotropy feature of the universe in the Bianchi type-VI0 space time. Some important features of the model, thus obtained, have been di...
متن کاملQuark mean field model for nuclear matter and finite nuclei
We study nuclear matter and finite nuclei in terms of the quark mean field (QMF) model, in which we describe the nucleon using the constituent quark model. The meson mean fields, in particular the σ meson, created by other nucleons act on quarks inside a nucleon and change the nucleon properties in nuclear medium. The QMF model predicts an increasing size of the nucleon as well as a reduction o...
متن کاملStrangelets and Strange Quark Matter
As it has been discussed widely during this conference, strangeness opens a new dimensions to nuclear physics. Insofar, systems with strangeness number S = −1,−2 have been discussed. Here we want to examine the unknown domain of finite nuclear systems with S < −2. There have been speculations about the existence of finite systems of strange quark matter (strangelets) and strange hadronic matter...
متن کاملStrange nucleon form factors in the perturbative chiral quark model
We apply the perturbative chiral quark model at one loop to calculate the strange form factors of the nucleon. A detailed numerical analysis of the strange magnetic moments and radii of the nucleon, and also the momentum dependence of the form factors is presented. PACS: 12.39.Fe, 12.39.Ki, 13.40.Gp, 14.20.Dh
