Dibaryons – a new state of matter?

New results in the field of dibaryons are discussed concentrating on the d$^{*}$(2380) resonance with I(J$^{P}$) = 0(3$^{+}$), which has been observed first in the double-pionic fusion to deuterium and meanwhile also in neutron-proton scattering — establishing it thus as a genuine s-channel resonance. Double-pionic fusion reactions to the He isotopes demonstrate that this resonance survives also in a nuclear surrounding. It also has been shown to contribute to dilepton production helping thus to resolve the so-called DLS puzzle. Moreover, the existence of dibaryons has also an impact on the equation of state for nuclear matter
