“…Exotic configurations have been suggested as a possible contribution to the structure in nuclei. Overlapping baryonic states could contain exotic configurations such as 6-quark bags [308], hidden color states [309,310,311], or multi-diquark contributions [312]. Such states allow for more direct sharing of momentum between quarks in different nucleons, yielding predictions that they could have a significant contribution of super-fast quarks, quarks with momentum fraction well above what is easily achievable through simple smearing of the nucleon PDFs [243,313].…”

We summarize the ongoing scientific program of the 12 GeV Continuous Electron Beam Accelerator Facility (CE-BAF) and give an outlook into future scientific opportunities. The program addresses important topics in nuclear, hadronic, and electroweak physics including nuclear femtography, meson and baryon spectroscopy, quarks and gluons in nuclei, precision tests of the standard model, and dark sector searches. Potential upgrades of CEBAF are considered, such as higher luminosity, polarized and unpolarized positron beams, and doubling the beam energy.

“…Additional contributions that have been examined are virtual constituents of the nucleus which are not present in a nucleon. In the dense environment of a nucleus, one may have color-singlet clusters of 6, 9,... valence quarks [39,40] or hidden-color configurations [41,42]. The PDFs of these exotic objects is expected to differ significantly from the sum of individual nucleons, leading to a modification to the nuclear PDF.…”

“…Production of multiquark systems with possible diquark structure [222,[239][240][241][242] on large angles can be enhanced due to double diquark-quark scattering [205,224]. Inclusive and two-particle correlation studies with production of light nuclei and antinuclei should help establishing two production mechanism stages: multiparton scattering and fragmentation/fusion process [205,224] (Fig.…”

Nuclotron based Ion Collider fAcility (NICA) project is in progress at the Joint Institute for Nuclear Research and will start experiments with heavy ions. In the context of the NICA Hadronic Physics programme double polarized pp-, dd-and pd-collisions even at lower energies of √ sNN = 3.4 − 10 GeV, which will be accessible already at the initial stage of experiments,are essential tools for precise understanding the spin dependence of the nucleon-nucleon strong interactions, in both elastic and deep-inelastic regimes. A special interest is interaction in few baryon systems at double strangeness, charm and beauty thresholds.For instance, polarized large-angle elastic pp and pn scattering near the charm threshold allows one to get an access to properties of possible exotic multiquark states and their relation to the states recently observed at LHCb.Large angle scattering of protons and deuterons on the deuteron contains unique information on the short-range structure of the deuteron, its non-nucleonic degrees of freedom and also on color transparency phenomenon. Furthermore, double polarized proton-deuteron scattering offer a possibility to test the Standard Model through the search for time-invariance (or CP-invariance under CPT symmetry) violation and parity-violation in single-polarized scattering. This paper contains suggestions for experiments with usage of the Spin Physics Detector (SPD) and discusses perspectives of the first stage of the SPD Programme. This includes experiments with non-polarized beams too as well as collisions like 12 С-12 С and 40 Сa-40 Ca.9 Multiquark correlations and exotic hadron state production 9 9.1 Multiquark correlations and exotic state production at SPD NICA . . . .
