Triangle singularity as the origin of $X_{0} (2900)$ and $X_{1} (2900)$ observed in $B^{+} \to D^{+} D^{-} K^{+}$

Xiao-Hai Liu, Mao-Jun Yan, Hong-Wei Ke +2

The LHCb collaboration reported the observation of a narrow peak in the $D^{-} K^{+}$ invariant mass distributions from the $B^{+} \to D^{+} D^{-} K^{+}$ decay. The peak is parameterized in ter…

Peaks within peaks and the possible two-peak structure of the Pc(4457): the effective field theory perspective

Fang-Zheng Peng, Jun-Xu Lu, Mario Sánchez Sánchez +2

The LHCb pentaquarks -- the $P_{c} (4312)$ , $P_{c} (4440)$ and $P_{c} (4457)$ -- have been theorized to be $Σ_{c} D ˉ$ and $Σ_{c} D ˉ^{*}$ S-wave molecules. Here we explore the possibilit…

New spectrum of negative-parity doubly charmed baryons: Possibility of two quasistable states

Mao-Jun Yan, Xiao-Hai Liu, Sergi Gonzàlez-Solís +4

The discovery of $Ξ_{cc}^{++}$ by the LHCb Collaboration triggers predictions of more doubly charmed baryons. By taking into account both the $P$ -wave excitations between the two c…
