Three-body Confinement Forces in a Realistic Constituent Quark Model
نویسنده
چکیده
We implement a three-body confinement force, introduced on an algebraic basis, into a semirelativistic version of the Goldstone-boson-exchange constituent quark model. By solving the Faddeev equations we show that this interaction can increase the gap between singlet and colour states, such as the latter can be ignored. We present results for a ∆and a Y-shape threebody interaction in terms of the relative strength of the three-body versus the usual two-body confinement interaction. PACS: 12.39.-x,12.39.Pn,12.40.Yx

We show that in realistic constituent quark models based on a two-body confinement interaction color states appear in the middle of the experimentally known spectrum. To avoid this situation we implement a three-body confinement interaction, introduced on an algebraic basis, into a semirela-tivistic version of the Goldstone boson exchange constituent quark model and by solving the Faddeev equat...

We implement a three-body confinement force, introduced on an algebraic basis, into a semirelativistic version of the Goldstone-boson-exchange constituent quark model. By solving the Faddeev equations we show that this interaction can increase the gap between singlet and colour states, such as the latter can be ignored and the known baryons can be described as q3 systems. We analyze the effect ...
متن کاملHypercentral Constituent Quark Model and Isospin for the Baryon Static Properties
So far the static properties of hadrons have been introduced in various models. The static properties of hadrons (charge radius, magnetic moment, etc.) are useful for understanding the quark structure of hadron. In this work we have introduced the hypercentral constituent quark and isospin dependent potentials. Here constituent quarks interact with each other via a potential in which we have ta...

In this article nucleons are discussed based on constituent quark model. This model aims at studying the forces among three particles and the corresponding standard two-body potential contribution. The quark potential contains a hypercentral interaction. The confining potential is composed of four components,color charge, the oscillatory potential, the interaction quark and neutral gluon, and...
متن کاملOn a three-body confinement force in hadron spectroscopy
Recently it has been argued that a three-body colour confinement interaction can affect the stability condition of a three-quark system and the spectrum of a tetraquark described by any constituent quark model. Here we discuss the role of a three-body colour confinement interaction in a simple quark model and present some of its implications for the spectra of baryons, tetraquarks and six-quark...
