Using the decay ψ(4160) -> X(3872) γ to probe the molecular content of the X(3872)

Arman Margaryan, Roxanne P Springer

The X(3872) has non-charmonium-like properties, such as decay processes that seem to violate isospin, and a mass that lies unexpectedly close to the neutral-D-plus-neutral-D-excite…
