Pentaquarks with anticharm or beauty revisited

Abstract

We use a constituent model to analyze the stability of pentaquark $\bar{Q}qqqq$ configurations with a heavy antiquark $\bar{c}$ or $\bar{b}$, 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.
