The mechanism of open-flavor strong decays

PDF Version Also Available for Download.

Description

In this contribution the author discusses models of two-body strong hadron decays. These models are expected to play a vital role in future attempts to identify unconventional hadrons such as glueballs and hybrids, through accurate predictions of the decay modes of conventional q{anti q} states. First, he reviews the most commonly used decay model, which is the {sup 3}P{sub 0} model developed by Micu and LeYaouanc et al., and show some of its successful predictions. Predictions of the {sup 3}P{sub 0} model for some newly discovered states are also given. Finally he discusses some attempts to identify the fundamental QCD ... continued below

Description

In this contribution the author discusses models of two-body strong hadron decays. These models are expected to play a vital role in future attempts to identify unconventional hadrons such as glueballs and hybrids, through accurate predictions of the decay modes of conventional q{anti q} states. First, he reviews the most commonly used decay model, which is the {sup 3}P{sub 0} model developed by Micu and LeYaouanc et al., and show some of its successful predictions. Predictions of the {sup 3}P{sub 0} model for some newly discovered states are also given. Finally he discusses some attempts to identify the fundamental QCD process which underlies q{anti q} pair production in the {sup 3}P{sub 0} model. His results indicate that the dominant q{anti q} pair production process is usually pair production through the linear scalar confining interaction. Pair production from OGE in most cases is found to be a smaller amplitude, with the notable exception of {sup 3}P{sub 0} {yields} {sup 1}S{sub 0} decays such as f{sub 0}(q{anti q}) {yields} {pi}{pi}.
