Effect of tree level and mean field improvement on the light hadron spectrum in quenched QCD
... The correlators used to extract the hadron masses are listed in Table I; for further details see @ 17 # . We computed meson correlators using quarks degenerate and nondegener- ate in mass, giving three possible ...

Threshold effects in hadron spectrum: a new spectroscopy?
... The meson-meson interaction from the inner q − q interactions is obtained by using the Resonating Group Method (RGM). Such method requires to know in advance the wave functions of the mesons, which are calculated by ...

Quenched QCD withO(a)improvement: The spectrum of light hadrons
... The first observation is that, on the whole, the two simu- lations agree quite well, although the errors quoted by CP- PACS are in general much smaller. This confirms the previ- ous conclusion that the quenched light ...

QCD vs. the Centrifugal Barrier: a New QCD Effect
... One well-established pillar of QCD is the quark model [3], which has been the accepted framework for classifying the hadron spectrum. This is a schematic model for the mesons and baryons in which quarks are ...

Exotic Hadron Spectroscopy
... Abstract. Since ten years ago experiments have been observing a host of exotic states decaying into heavy quarkonia. The interpretation of most of them still remains uncertain and, in some cases, controversial. Notwith- ...
