Pentaquarks with anticharm or beauty revisited
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 th...
