@article{Clement2021DibaryonsMV, title={Dibaryons: Molecular versus compact hexaquarks}, author={H. Clement and T. Yu. Skorodko}, journal={Chinese Physics C}, year={2021}, volume={45} }
Hexaquarks constitute a natural extension of complex quark systems, just as tetra- and pentaquarks do. To this end, the current status of in both experiment and theory is reviewed. Recent high-precision measurements in the nucleon-nucleon channel and analyses thereof have established as an indisputable resonance in the long-sought dibaryon channel. Important features of this state are its narrow width and deep binding relative to the threshold. Its decay branchings favor theoretical…

In this talk we show that the two-step sequential one pion production mechanism, np(I = 0) → π −pp, followed by the fusion reaction pp → π +d, can explain the narrow peak identified with a “d ∗…

We develop a model for the pp→ πd reaction based on the pp→ ∆(1232)N transition followed by ∆(1232)→ πN ′ decay and posterior fusion of NN ′ to give the deuteron. We show that the triangle diagram…

We study the two-baryon system with two units of charm looking for the possible existence of a loosely bound state resembling the $H$ dibaryon. We make use of a chiral constituent quark model tuned…
Pion production in nucleon-nucleon collisions and the issue of dibaryons

Pion production in nucleon-nucleon collisions is tightly connected with the issue of dibaryons. After having established the existence of the narrow dibaryon resonance d* (2380) with I(JP) = 0(3+) by…

We confirm our previous prediction of a d* state with I(J(P)) = 0(3(+)) [Phys. Rev. C 60, 045203 (1999)] and report for the first time based on a microscopic calculation that d* has about 2/3 hidden…
