Femtoscopy correlation functions and mass distributions from production experiments
M. Albaladejo, A. Feijoo, J. Nieves +2
We discuss the relation between the Koonin-Pratt femtoscopic correlation function (CF) and invariant mass distributions from production experiments. We show that the equivalence is…
Testing the molecular nature of the with the and reactions
Jing Song, Wei-Hong Liang, Chu-Wen Xiao +2
We report on the reactions and ), and calculate the mass distributions $\frac{{\rm d}Î…
and decay into and and the spin of the states
Zi-Ying Yang, Jing Song, Wei-Hong Liang +1
We address the issue of the width and spin assignment of the and pentaquark states. We calculate the partial decays widths of the particles into , $\…
How to unravel the nature of the state from correlation functions
Hai-Peng Li, Chu-Wen Xiao, Wei-Hong Liang +3
We calculate the correlation functions for the , and states, which in the chiral unitary approach predict an excited $Σ^*(1/2^-…
Study of the exotic three-body system
Qing-Yu Zhai, Raquel Molina, Eulogio Oset +1
We have studied the system in the framework of the Fixed Center Approximation to the Faddeev equations, taking the exotic system as the cluster a…
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…
