Spectral quark model and low-energy hadron phenomenology
We propose a spectral quark model which can be applied to low energy hadronic physics. The approach is based on a generalization of the Lehmann representation of the quark propagator. We work at the one-quarkloop level. Electromagnetic and chiral invariance are ensured with the help of the gauge technique which provides particular solutions to the Ward-Takahashi identities. General conditions o...
متن کاملLow Energy Hadron Physics
Ask a group of particle theorists about low energy hadron physics and they will say that this is a subject that belongs to the age of the dinosaurs. However, it is GeV physics that controls the outcome of every hadronic interaction at almost every energy. Confinement of quarks and gluons (and any other super-constituents) means that it is the femto-universe that determines what experiments dete...
متن کاملLessons from Hadron Phenomenology
The main effort of our light-front community has been in the past ten years to develop new techniques for solving QCD, be it DLCQor renormalisationgroupbased methods (for review see [1]). In practice the usefulness of any procedure (which includes the question of convergence) is often determined by how well its first approximation captures the essential features of the system under consideratio...
متن کاملFLIC Fermions and Hadron Phenomenology
A pedagogical overview of the formulation of the Fat Link Irrelevant Clover (FLIC) fermion action and its associated phenomenology is described. The scaling analysis indicates FLIC fermions provide a new form of nonperturbative O(a) improvement where near-continuum results are obtained at finite lattice spacing. Spin-1/2 and spin-3/2, even and odd parity baryon resonances are investigated in qu...
متن کاملQuantum Groups in Hadron Phenomenology
We show that application of quantum unitary groups, in place of ordinary flavor SU (n f), to such static aspects of hadron phenomenology as hadron masses and mass formulas is indeed fruitful. The so-called q-deformed mass formulas are given for octet baryons 1 2 + and decuplet baryons 3 2 + , as well as for the case of vector mesons 1 − involving heavy flavors. For deformation parameter q, rigi...
