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/ψϕ,\, D_{s}^{\ast}\bar{D}_{s}^{\…
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 …
On the , and as dynamically generated states and their SU(3) partners
Mao-Jun Yan, Jorgivan M. Dias, Adolfo Guevara +2
In this work, we interpret the newly observed resonance with exotic quantum numbers in the sector, reported by the BESIII Collaboration, as a dyna…
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…
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…
Hadronic decays of the heavy-quark-spin molecular partner of
Zhao-Sai Jia, Mao-Jun Yan, Zhen-Hua Zhang +3
Starting from the hypothesis that the discovered at LHCb is a hadronic molecule, we consider the partial width of its heavy quark spin part…
Triangle singularity in via the loop and possible precise measurement of the mass
Mao-Jun Yan, Ying-Hui Ge, Xiao-Hai Liu
We investigate the decay via the rescattering diagram. The line shape of the distribution curve around $D_{s1}(2536)…
The pentaquark and its partners in the molecular picture
Mao-Jun Yan, Fang-Zheng Peng, Mario Sánchez Sánchez +1
The LHCb collaboration has detected a new hidden-charm pentaquark with the quantum numbers of a baryon: the . This pentaquark will be interpreted as a $\bar{D}_…
Light- and heavy-quark symmetries and the , , , and resonances
Fang-Zheng Peng, Mao-Jun Yan, Mario Sánchez Sánchez +1
The heavy hadron spectrum is constrained by symmetries, of which two of the most important ones are heavy-quark spin and SU(3)-flavor symmetries. Here we argue that in the molecula…
Interpretations of the new LHCb pentaquark state
Mao-Jun Yan, Fang-Zheng Peng, Mario Sánchez Sánchez +1
Recently the LHCb collaboration has observed a new pentaquark state, the . Owing to its proximity to the , , and $\bar{D} Σ_…
Subleading contributions to the decay width of the tetraquark
Mao-Jun Yan, Manuel Pavon Valderrama
Recently the LHCb collaboration has announced the discovery of the tetraquark. Being merely a few hundred below the threshold, the is…
Axial meson exchange and the and resonances as heavy hadron molecules
Mao-Jun Yan, Fang-Zheng Peng, Mario Sánchez Sánchez +1
Early speculations about the existence of heavy hadron molecules were grounded on the idea that light-meson exchanges forces could lead to binding. In analogy to the deuteron, the…
Heavy-hadron molecular spectrum from light-meson exchange saturation
Fang-Zheng Peng, Mario Sánchez Sánchez, Mao-Jun Yan +1
If known, the spectrum of heavy-hadron molecules will be a key tool to disentangle the nature of the exotic states that are being discovered in experiments. Here we argue that the…
