| 英文摘要 | The LHCb collaboration has detected a new hidden-charm pentaquark with the quantum numbers of a ? baryon: the P?,ys(4338). This pentaquark will be interpreted as a over bar Ds?c - over bar D Xi c resonance within a contact -range theory. Here we briefly comment on the relation of the new P?,ys(4338) with the P?,ys(4459). We find that the P?,ys(4338) and P?,ys(4459) both accept a common description in terms of the same parameters, which predicts the existence of a few additional PN,y, P?,ys, P sigma,ys, and P Xi,yss molecular pentaquarks composed of a charmed antimeson and an antitriplet charmed baryon. The most robust of these predicted pentaquarks is a P?,ys with a mass in the (4235-4255) MeV range, while other two interesting ones are a PN,y (4150) and a P sigma,ys(4335), the latter basically at the same mass as the P?,ys(4338), with which it might mix owing to isospin symmetry breaking effects. |
