Is glueball exchange important in the qq¯ potential?
Abstract
Assuming ι(1440) to be a glueball, it is shown that its exchange in the qq¯ system yields a potential that is negligible compared to the one-gluon-exchange part. This is because the glueball-quark coupling constant, deduced from experimental data, is only about a tenth of the fine-structure constant.
