Interpretations of the new LHCb $$P_c(4337)^+$$ pentaquark state

Abstract Recently the LHCb Collaboration has observed a new pentaquark state, $$P_c(4337)^+$$ P c ( 4337 ) + . Owing to its proximity $$\chi _{c0}(1S) p$$ ? 0 1 S p , $${\bar{D}}^* \varLambda _c$$ D ¯ ? ? $${\bar{D}} \varSigma ? and _c^*$$ thresholds, this might very well be meson–baryon bound state. However spin parity have not been determined yet none of previous possibilities can ruled out.We briefly explore few these options consequences they entail in present manuscript: (i) (ii) $$P_c(4312)^+$$ 4312 states close threshold, respectively, where Breit–Wigner mass correspond location poles, (iii) locations explained terms - coupled channel dynamics. This last option, though most probable explanation, is still potentially compatible with double peak solution $$P_{cs}(4459)^0$$ cs 4459 what we know As byproduct explorations, conjecture existence series anticharmed meson – antitriplet charmed baryon calculate their masses.
