Abstract It was demonstrated in a series of papers employing unitarized chiral perturbation theory that the phenomenology scalar open-charm state, $$D_0^*(2300)$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mrow> <mml:msubsup> <mml:mi>D</mml:mi> <mml:mn>0</mml:mn> <mml:mo>∗</mml:mo> </mml:msubsup> <mml:mo>(</mml:mo> <mml:mn>2300</mml:mn> <mml:mo>)</mml:mo> </mml:mrow> </mml:math> , can be understood as interplay two poles, corresponding to scalar-isospin doublet states...
The internal structure of the charm-strange mesons $D_{s0}^*(2317)$ and $D_{s1}(2460)$ are subject intensive studies. Their widths small because they decay dominantly through isospin-breaking hadronic channels $D_{s0}^*(2317)^+\to D_s^+\pi^0$ $D_{s1}(2460)^+\to D_s^{*+}\pi^0$. can also into final states $D_s^+\pi\pi$, conserving isospin. In that case there is, however, a strong suppression from phase space. We study transition D_s^+\pi^+\pi^-$ in scenario is $D^*K$ molecule. $\pi\pi$ state...

It was demonstrated in a series of papers employing unitarized chiral perturbation theory that the phenomenology scalar open-charm state, $D_0^*(2300)$, can be understood as interplay two poles, corresponding to scalar-isospin doublet states with different SU(3) flavor content. Within this formalism lightest open charm positive parity emerge being dynamically generated from scattering Goldstone-boson octet off $D$ mesons, picture at same time solves various problems experimental observations...
