Track: Baryon Spectroscopy
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 ... More

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 ... More

Track: Baryon Spectroscopy
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 ... More
