Precision measurement of the X(3872) mass in J/psi pi(+) pi(-) decays.

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/psi pi(+)pi(-) using 2.4 fb(-1) of integrated luminosity from pp collisions at square root(s)=1.96 TeV, collected with the CDF II detector at the Fermilab Tevatron. The possible existence of two nearby mass states is...
