The nature of the Pc(4312), Pc(4440) and Pc(4457) pentaquarks is a fascinating theoretical question. Within the molecular picture their more usual interpretation is that of I=12 D¯Σc and D¯⁎Σc bound states. Here we argue in favor of interpretin

Abstract Recently the LHCb Collaboration has observed a new pentaquark state, the $$P_c(4337)^+$$ P c ( 4337 ) + . Owing to its proximity to the $$\chi _{c0}(1S) p$$ χ c 0 ( 1 S ) p , $${\bar{D}}^* \varLambda _c$$ D ¯ ∗ Λ c , $${\bar{D}} \varSig

Abstract The observation of the $$P_{cs}(4459)$$ P cs ( 4459 ) by the LHCb collaboration adds a new member to the set of known hidden-charm pentaquarks, which includes the $$P_c(4312)$$ P c ( 4312 ) , $$P_c(4440)$$ P c ( 4440 ) and $$P_c(4457)$$ P c

Abstract The LHCb collaboration recently reported the observation of a narrow peak in the $$D^- K^+$$ D - K + invariant mass distributions from the $$B^+\rightarrow D^+ D^- K^+$$ B + → D + D - K + decay. The peak is parameterized in terms of two re

In this work, we interpret the newly observed η1(1855) resonance with exotic JPC=1−+ quantum numbers in the I=0 sector, reported by the BESIII Collaboration, as a dynamically generated state from the interaction between the lightest pseudoscalar m

Starting from the hypothesis that the $T_{cc}^+$ discovered at LHCb is a $D^{\ast+} D^0/D^{\ast 0}D^+$ hadronic molecule, we consider the partial width of its heavy quark spin partner, the $T_{cc}^{\ast +}$ as a $D^{\ast +} D^{\ast 0}$ shallow bound
