Relativistic Unitarized Quark/Meson Model in Momentum Space
نویسندگان
چکیده
An outline is given how to formulate a relativistic unitarized constituent quark model of mesons in momentum space, employing harmonic quark confinement. As a first step, the momentum-space harmonic-oscillator potential is solved in a relativistically covariant, three-dimensional quasipotential framework for scalar particles, using the spline technique. Then, an illustrative toy model with the same dynamical equations but now one qq̄ and one meson-meson channel, coupled to one another through quark exchange describing the P0 mechanism, is solved in closed form on a spline basis. Conclusions are presented on how to generalize the latter to a realistic multichannel quark/meson model.

Relativistic Meson Spectroscopy in Momentum Space Typeset Using Revt E X 1
In this paper a relativistic quantum theory introduced by de Groot and Ruijgrok in 1975, is used as a quark model in momentum space. The complete spectrum, with the exception of the selfconjugate light unflavoured mesons, is calculated. The potential used consists of an one-gluon-exchange (OGE) part and a confining part. For the confining part a relativistic generalization of the linear plus co...
متن کاملWeak Form Factors for Heavy Meson Decays
We calculate the form factors for weak decays of B(s) and D(s) mesons to light pseudoscalar and vector mesons within a relativistic dispersion approach based on the constituent quark picture. This approach gives the form factors as relativistic double spectral representations in terms of the wave functions of the initial and final mesons. The form factors have the correct analytic properties an...
متن کاملResonance recombination model and quark distribution functions in the quark-gluon plasma
We investigate the consequences of space-momentum correlations in quark phase-space distributions for coalescence processes at the hadronization transition. Thus far it has been proved difficult to reconcile such correlations with the empirically observed constituent quark number scaling (CQNS) at the Relativistic Heavy Ion Collider (RHIC). To address this problem we combine our earlier develop...
متن کاملComment on “Understanding the scalar meson q¯q nonet” hep-ph/9806246
It is shown that the incomplete scalar meson nonets found by Törnqvist [1] and Törnqvist & Roos [2], employing a new version of the Helsinki unitarized quark model, should in fact be complete, including an as yet unconfirmed light K 0 below 1 GeV (old κ) and the established f0(1500). A detailed comparison is presented with the predictions of the Nijmegen unitarized meson model, in which two com...
متن کاملRelativistic quark-antiquark bound-state problem with spin-dependent interactions in momentum space.
The work described in this paper is the first step toward a relativistic three-quark bound-state calculation using a Hamiltonian consistent with the Wigner-Bargmann theorem and macroscopic locality. We give an explicit demonstration that we can solve the two-body problem in momentum space with spin-dependent interactions. The form of the potential is a combination of linear+Coulomb+spin-spin+sp...
