In this paper, we discuss the general features of the effective range expansion, including the content of its parameters with respect to near-threshold states and the necessary modifications in the presence of coupled channels, isospin violations, and unstable constituents. As illustrative examples, we analyze the properties of the chi(c1)(3872) and T-cc(+) states, supporting the claim that these exotic states have a predominantly molecular nature.
We discuss some general features of the effective range expansion, the content of its parameters with respect to the nature of the pertinent near-threshold states and the necessary modifications in the presence of coupled channels, isospin violations and unstable constituents. As illustrative examples, we analyse the properties of the chi(c1)(3872) and T-cc(+) states supporting the claim that these exotic states have a predominantly molecular nature.
