Chromoelectric binding: string potential<br />
The good surprise is that this potential gives better binding than<br />
<strong>the</strong> simple additive <strong>model</strong>,<br />
Hence, (cc¯q¯q), marginally bound in <strong>the</strong> additive <strong>model</strong>, should<br />
be stable with this improved <strong>quark</strong> dynamics<br />
Hence, beyond double-charm baryons, one could look at double<br />
charm mesons, a genuine exotic,<br />
For instance, since e + e − → J/ψ + ηc is observed (double charm<br />
production), TQQ + ¯ D + ¯ D + · · · could be observed.<br />
