The Effective Meson Theory,. Unfortunately, the effective meson theory of large . QCD cannot be constructed explicitly. The primary aim of the investigations using the NJL model was to understand the emergence of the effective meson theory [ER86] and in particular the appearance of baryons as solitons out of the quark flavor 作者: 牢騷 時(shí)間: 2025-3-22 00:58 作者: exophthalmos 時(shí)間: 2025-3-22 05:32 作者: 壓倒性勝利 時(shí)間: 2025-3-22 09:24

Constants and functional reductionave been restricted to the case that meson fields are frozen to its vacuum expectation value. A complete investigation of Quantum Flavor Dynamics would require the explicit baryon field as introduced in Sect. 5.1 as well as the non-perturbative (solitonic) meson fields, especially the hedgehog (4.3) for the pseudoscalar field.作者: 不可救藥 時(shí)間: 2025-3-24 07:33 作者: innate 時(shí)間: 2025-3-24 12:02 作者: outer-ear 時(shí)間: 2025-3-24 16:31

Via functional integral techniques a Faddeev equation for baryons describing them as bound states of a diquark and a quark is derived. Finally, a unification of these two complementary pictures of baryons is proposed.作者: 愛好 時(shí)間: 2025-3-25 14:22 作者: 連累 時(shí)間: 2025-3-25 19:14 作者: callous 時(shí)間: 2025-3-25 22:00 作者: ostensible 時(shí)間: 2025-3-26 01:48 作者: biopsy 時(shí)間: 2025-3-26 06:03 作者: insomnia 時(shí)間: 2025-3-26 12:00

The Effective Meson Theory,e generic form predates QCD. It was as early as 1961 that Y. Nambu and G. Jona-Lasinio studied a model with a chirally symmetric local four-point interaction [NJL61].
