Baryonic masses based on the NJL model
نویسندگان
چکیده
We employ the Nambu Jona–Lasinio model to determine the vacuum pressure on the quarks in a baryon and hence their density inside. Then we estimate the baryonic masses by implementing the local density approximation for the mean field quark energies obtained in a uniform and isotropic system. We obtain a fair agreement with the experimental masses. PACS: 12.39.-x, 12.39.Ba, 12.39.Fe, 14.20.-c, 14.20.Dh

متن کاملFaddeev Approach to the Octet and Decuplet Baryons
A relativistic Faddeev model for the baryon octet is extended to treat the baryon decuplet. We find that after determining the model parameters in the mesonic sector the masses of both nucleon and delta deviate by less than 5% from the experimental data and show only a very weak dependence on the constituent quark mass. Recently relativistic Faddeev quark–models have been developed for the nu-c...
متن کاملFormation of Large Structures in the Acceleration Universe with a Hybrid Expansion Law
In the current paper, we have studied the effect of dark energy on for-mation where dark energy exists in the background. For this purpose, we used both WMAP9 and Planck data to study how the radius changes with redshift in these mod-els. We used different data sets to fix the cosmological parameters to obtain a solution for a spherical region under collapse. The mechanism of structure formation f...

We give an introduction to the dynamical symmetry breaking with large anomalous dimension. This is the basis of tightly bound composite Higgs models such as walking technicolor, strong ETC technicolor and top quark condensate, which are all characterized by the large anomalous dimension, γm ≃ 1 (walking technicolor), 1 < γm < 2 (strong ETC technicolor) and γm ≃ 2 (top quark condensate) due to n...
متن کاملRecent Results in the Njl Model with Heavy Quarks
We investigate the interplay of chiral and heavy quark symmetries by using the NJL quark model. Heavy quarks with finite masses mQ as well as the limit mQ → ∞ are studied. We found large corrections to the heavy mass scaling law for the pseudoscalar decay constant. The influence of external momenta on the shape parameters of the Isgur-Wise form factor is discussed.
