Off-shell ambiguities in correlation functions: strategies to minimize them
R. Molina, E. Oset
We face here the problem of uncertainties in correlation functions due to the freedom in the off-shell dependence of the wave functions, or equivalently, off-shell ambiguities in t…

One or two poles for the ?
R. Molina, Wei-Hong Liang, Chu-Wen Xiao +2
In this talk, we present a new interpretation for the recently observed resonance. We recall that the chiral unitary approach for the interaction of pseudoscalar mesons…
