We present in this talk our recent progress made on the investigations of d*(2380) in a chiral quark model. In particular, we show that the effects of hidden-color channel in Delta-Delta system are less important than those in the traditional quark model calculations once the single baryon and the baryon-baryon system are treated in a consistent way in a microscopic quark model calculation.

We conduct a study of the interaction of the K¯ Ξ, ηΩ(s-wave), and K¯ Ξ(d-wave) channels within a
coupled channel unitary approach where the transition potential between the K¯ Ξ and ηΩ channels is
obtained from chiral Lagrangians. We find that all data including the recent Belle experiment on Γ(Ω→πK¯ Ξ)/Γ(Ω→K¯ Ξ), are compatible with the molecular picture stemming from m

Belle collaboration measured the ratios of the branching fractions of the newly observed Omega(2012) excited state.We revisit the Omega(2012) from the molecular perspective where it appears to be a dynamically generated state with spin−parity 3/2- from the coupled channels interactions of the Kbar Xi(1530) and eta Omega and Kbar Xi. With the model parameters, it is shown that the ratio of these

We study the two step sequential one pion production mechanism,$np(I=0)\to\pi^−pp$, followed by the fusion reaction $pp\to\pi^+d$,to describe the $np\to\pi^+\pi^−d$ reaction where a narrow peak has been identified with a “d(2380)” dibaryon. We find that the second step $pp\to\pi^+d$ is driven by a triangle singularity.Without invoking a dibaryon, the combined cross sections produce a narro
