Three-body Confinement Force in a Realistic Constituent Quark Model
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 ...

We present results for a ∆and a Y-shape threebody interaction in terms of t...
متن کاملHeavy Quark Solitons : Towards Realistic Masses
A generalization of the eective meson Lagrangian possessing the heavy quark symmetry to nite meson masses is employed to study the meson mass dependence of the spectrum of S{ and P wave baryons containing one heavy quark or anti-quark. These baryons are described as respectively heavy mesons or anti-mesons bound in the background of a soliton, which is constructed from light mesons. No further ...
متن کاملQcd Thermodynamics with Almost Realistic Quark Masses
Ongoing calculations on the QCDOC supercomputer at Brookhaven National Laboratory and the APEnext installation at the University of Bielefeld aim to determine the critical temperature of the QCD phase transition as well as the equation of state with almost realistic quark masses. We will discuss preliminary results of the quark mass and cut-off dependence of order parameters, susceptibilities, ...
متن کاملQuark–lepton mass relation in a realistic A4 extension of the Standard Model
Article history: Received 25 March 2013 Received in revised form 29 May 2013 Accepted 29 May 2013 Available online 1 June 2013 Editor: J. Hisano We propose a realistic A4 extension of the Standard Model involving a particular quark–lepton mass relation, namely that the ratio of the third family mass to the geometric mean of the first and second family masses are equal for down-type quarks and c...
