Measurement of the dipion mass spectrum in X(3872)→J/ψπ+π- decays

We measure the dipion mass spectrum in X(3872)→J/ψπ+π- decays using 360pb-1 of p̄p collisions at s=1.96TeV collected with the CDFÂ II detector. The spectrum is fit with predictions for odd C-parity (S13, P11, and DJ3) charmonia decaying to J/ψπ+π-, as well as even C-parity states in which the pions...
