Precision Measurement of the X(3872) Mass in J/ psi pi + pi - Decays
We present an analysis of the mass of the X(3872) reconstructed via its decay to J/ψπ[superscript +]π[superscript -] using 2.4 fb[superscript -1] of integrated luminosity from pp̅ collisions at √s=1.96 TeV, collected with the CDF II detector at the Fermilab Tevatron. The possible existence of two...
