Scalar Meson Photoproduction
The light-quark non-strange scalar mesons a0(980), f0(980), f0(1370), a0(1450), f0(1500) and f0(1710) are of great interest as there is no generally accepted view of their structure which can encompass qqq̄q̄, molecular, qq̄ and glueball states in various combinations. It has been shown previously that the radiative decays of the scalar mesons to ρ and ω are a good probe of their structure and pro...
متن کاملLight scalar meson spectrum
We discuss the classification of the light scalar mesons with mass below 2 GeV into qq̄ nonets and glueballs. The information on production and decay of these states, in particular recent information on the f0(980), f0(400−1200) (or σ(600)) and f0(1500) is considered. Although the data are not yet very precise the recent information is in favour of the previously developed scheme which includes ...
متن کاملScalar confinement in a relativistic hydrogenlike meson
Wavefunctions of a relativistic heavy quark-light quark (Q, q) system described by a Dirac hamiltonian with a linear Lorentz scalar confinement potential (S) are analyzed. It is found that they are normalizable and that they do account for the Klein paradox. Calculation of the slope of the Isgur-Wise function at zero recoil point gives ξ(1) = −1.05 ± 0.02. This suggests that if one considers re...
متن کاملExistence of a Light Strange Scalar Meson
We argue that a light isodoublet scalar meson, the K∗ 0 (700-1100) (old κ), does exist, as well as its recently rehabilitated [1] isoscalar nonet partner f0(400-800) (old σ or ǫ). This completes an extra, low-mass scalar-meson nonet, besides the usual scalar nonet around 1.4 GeV , which appears naturally due to the strong coupling of P -wave qq̄ systems to S-wave two-meson channels consisting of...
متن کاملThe Lightest Strange Scalar Meson ∗
I present the results of a recent calculation to determine the number of strange scalar resonances below 1.8 GeV based on the analytic properties of the experimental πK scattering amplitude. Only one resonance was found in the data, and this is readily identifiable as the K * 0 (1430). We found no evidence to support the κ(900).
