Threshold cusp effects to measure masses of radiatively decaying hadrons: The mass from the spectrum
Hai-Long Fu, Xu Zhang, Feng-Kun Guo +3
Hadrons that decay predominantly into final states containing photons are notoriously difficult to detect at hadron colliders. Prominent examples are the yet-unobserved …
Decoding the near-threshold and states via OZI-suppressed coupled-channel scattering
Mao-Jun Yan
To decode the near-threshold dynamics of the and states, we investigate the OZI-suppressed $\{D_{s}\bar{D}_{s},\, J/ÏÏ,\, D_{s}^{\ast}\bar{D}_{s}^…
Molecular pentaquarks from light-meson exchange saturation
Zi-Ying Yang, Fang-Zheng Peng, Mao-Jun Yan +2
Theoretical predictions for the spectrum of heavy meson-baryon bound states are a fundamental tool for disentangling the nature of the different pentaquark states that have been ob…
Molecular charmed baryons and pentaquarks from light-meson exchange saturation
Mao-Jun Yan, Fang-Zheng Peng, Manuel Pavon Valderrama
The spectrum of the baryons contains a few states whose nature is not clearly a three-quark composite and which might have a sizable baryon-meson component. Examples include…
Heavy- and light-flavor symmetry partners of the , the and the from light-meson exchange saturation
Fang-Zheng Peng, Mao-Jun Yan, Manuel Pavon Valderrama
The spectrum of the charmed meson-(anti)meson system is a fundamental tool for disentangling the nature of a few exotic hadrons, including the recently discovered …
Rethinking the as the isoquartet molecule
Fang-Zheng Peng, Mao-Jun Yan, Mario Sánchez Sánchez +1
The nature of the , and pentaquarks is a fascinating theoretical question. Within the molecular picture their more usual interpretation is that…
