“…Explanations that have been considered include regular charmonia; hybrid states; compact tetraquarks; hadronic molecules; mixtures of different components; and non-particle explanations such as kinematical effects and resonance interference. The experimental measurements and theoretical models have been summarised in a large number of review articles [206][207][208][209][210][211][212][213][214][215][216][217][218][219][220][221][222][223][224][225]. Readers are referred to these comprehensive reports for more details.…”

An electron ion collider has been proposed in China (EicC). It is anticipated that the facility would provide polarised electrons, protons and ion beams, in collisions with large centre-of-mass energy. This discussion highlights its potential to address issues that are central to understanding the emergence of mass within the Standard Model, using examples that range from the exploration of light-meson structure, through measurements of near-threshold heavy-quarkonia production, and on to studies of the spectrum of exotic hadrons.

“…( 8), the WiFunC model can in principle be used to describe the production of other nucleus-like systems with small binding energies if the approximate wave function of the produced system is known. One additional application of the WiFunC model could therefore be the production of exotic bound states such as the X (3872) or the Z cs (3985), if they are deuteron-like bound states [57][58][59][60][61][62].…”

On nuclear coalescence in small interacting systems

The formation of light nuclei can be described as the coalescence of clusters of nucleons into nuclei. In the case of small interacting systems, such as dark matter and $$e^+e^-$$ e + e - annihilations or pp collisions, the coalescence condition is often imposed only in momentum space and hence the size of the interaction region is neglected. On the other hand, in most coalescence models used for heavy ion collisions, the coalescence probability is controlled mainly by the size of the interaction region, while two-nucleon momentum correlations are either neglected or treated as collective flow. Recent experimental data from pp collisions at LHC have been interpreted as evidence for such collective behaviour, even in small interacting systems. We argue that these data are naturally explained in the framework of conventional QCD inspired event generators when both two-nucleon momentum correlations and the size of the hadronic emission volume are taken into account. To include both effects, we employ a per-event coalescence model based on the Wigner function representation of the produced nuclei states. This model reproduces well the source size for baryon emission and the coalescence factor $$B_2$$ B 2 measured recently by the ALICE collaboration in pp collisions.

Triply charmed dibaryons in the one boson exchange model

The pentaquark states, P c ð4312Þ, P c ð4440Þ, and P c ð4450Þ, can be nicely arranged into a multiplet of seven molecules ofD ðÃÞ Σ ðÃÞ c dictated by heavy quark spin symmetry, while the Ξ ðÃÞ cc Σ ðÃÞ c system can be related to theD ðÃÞ Σ ðÃÞ c system via heavy antiquark diquark symmetry. In this work, we employ the oneboson exchange model to study the interactions between Ξ ðÃÞ cc and Σ ðÃÞ c with constraints from the pentaquark system. We show that a multiplet of ten triply charmed dibaryons emerge naturally in the isospin-1=2 sector, while only three appear in the isospin-3=2 sector. In addition, we study their heavy quark flavor partners. Ten triply bottom diybaryons are found in the isospin-1=2 sector, while only nine are likely in the isospin-3=2 sector. Furthermore, the predicted mass splitting between the 0 þ Ξ cc Σ c state and its 1 þ counterpart is found to be consistent with the correlation implied by heavy antiquark diquark symmetry recently pointed out in Pan et al..
