Resumen
[EN] We use a constituent model to analyze the stability of pentaquark Q qqqq ̄ configurations with a heavy
antiquark c ̄ or ̄
b, and four light quarks uuds, ddsu or ssud. The interplay between chromoelectric and
chromomagnetic effects is not favorable, and, as a consequence, no bound state is found below the lowest
dissociation threshold.
