Scalar resonances in the final state interactions of the decays $D^{0} \to π^{0} π^{0} π^{0}, π^{0} π^{0} η, π^{0} η η$

Zhong-Yu Wang, Hiwa A. Ahmed, C. W. Xiao

We investigate the scalar resonances in the processes of $D^{0} \to π^{0} π^{0} π^{0}, π^{0} π^{0} η, π^{0} η η$ decays based on the chiral unitary approach for the final state i…

Is two-poles' $Λ (1405)$ one state or two?

Zhong-Yu Wang, Hiwa A. Ahmed, C. W. Xiao

To understand the nature of two poles for the $Λ (1405)$ state, we revisit the interactions of $K ˉ N$ and $π Σ$ with their coupled channels, where two-poles structure is found in…
