To that end, we have introduced a nonlocal version of the NJL model [10] that is able to repro-duce the Euclidean-space behavior of the quark mass seen in lattice simulations of QCD [9].

Celenza, Hu Li, C.M. Shakin, Qing Sun In a recent work we introduced a nonlocal version of the Nambu--Jona-Lasinio (NJL) model that was designed to generate a quark self-energy in Euclidean space that was similar to that obtained in lattice simulations of QCD. labouring jobs eastleigh

Webb19 feb. 2024 · Hot and dense quark matter with isospin and chiral imbalances is investigated in the framework of the (3+1) -dimensional Nambu–Jona-Lasinio model (NJL) in the large- N_c limit ( N_c is the number of quark colors). Its phase structure is considered in terms of barion – \mu _B, isospin – \mu _I and chiral isospin – \mu _ {I5} … WebbAccording to the NJL model, the threshold density for creation of s quarks in cold (T = 0) quark matter is ns thr 0.655 B fm-3 [36,37]. In the region n s thr, in cold (T = 0) quark matter only u and d quarks exist. Thus, when n B o0, an energy of M ou 2M od 3M ou 1100MeV is incident for a single baryon [37], as can be seen in Fig. 5.
