In this talk, I briefly summarize our progress made in the study of the structure and decay properties of the $d^{\ast}(2380)$, a dibaryon state recently reported by the WASA@COSY Collaboration. We studied the $d^{\ast}(2380)$ in a chiral quark model by performing a RGM dynamical investigation of the coupled-channel $\Delta\Delta$ + $CC$ interaction. The mass of $d^{\ast}(2380)$ is properly reprod

It is shown, that the energy dependence of the chiral based $\bar{K}N$ potentials, responsible for the occurrence of two poles in the $I=0$ sector, is the consequence of applying
the on-shell factorization introduced in [1]. When the dynamical equation is solved without this approximation, the second, unphysical, pole disappears. Accordingly, an energy-
independent $\bar{K}N$ potential was der

The reaction $p + d \rightarrow p + d + X$ was studied at 0.8--2.0 GeV proton beam energies with the ANKE magnetic spectrometer at the COSY synchrotron storage ring. The proton-deuteron pairs emerging with high momenta, 0.6--1.8 GeV/$c$, were detected at small angles with respect to the proton beam. Distribution above the reaction missing mass $M_{x}$ reveals a local enhancement near the threshold

In two-nucleon reactions it is rather common usage to take
into account the effect of the $\Delta(1232)$ excitation
by simply including an additional channel with the
$\Delta - N$ mass difference and free $\Delta$ width.
In the momentum space propagator this leads to a factor
$(E - \Delta M + i\Gamma /2)^{-1}$ and by its absolute square trivially to a resonant total cross section. In the

We discuss the structure and width of the recently established
$d^\ast (2380)$ dibaryon, confronting the consequences of the
Gal-Garcilazo Pion Assisted Dibaryons hadronic model with
those of quark motivated calculations. In particular, its relatively small width of about 70 MeV favors hadronic
structure for the $d^\ast (2380)$ dibaryon rather than a six-quark compact structure [1].
