The meson spectra beyond a $q\bar q$ description

High Energy Physics - Phenomenology 2009-11-10 v1

Abstract

Despite the apparent simplicity of meson spectroscopy there are some states which cannot be accommodated in the usual qqˉq\bar q structure. Among them there are either exotic states as the X(1600), or the recently measured charmed states DsJD_{sJ}^* and some of the light scalar mesons. We present a description of the light scalar mesons in terms of qqˉq\bar q and qqqˉqˉqq\bar q\bar q components.
