Production of X(3872) at PANDA

AbstractThe recently discovered X(3872) has many possible interpretations. We study the production of X(3872) with PANDA at GSI for the antiproton-proton collision with two possible interpretations of X(3872). One is as a loosely bound molecule of D mesons, while another is a 2P charmonium state chi(c1(2P)). Using effective couplings we are able to give numerical predictions for the production near the threshold and the production associated with pi(0). We also study the possible background near the threshold production for X(3872)-> J/psi pi(+)pi(-). With the designed luminosity 1.5 fb(-1) per year of PANDA we find that the event number of p (p) over bar -> J/psi pi(+)pi(-) near the threshold is at the order of 10(6)-10(8). Our study shows that two interpretations are distinguishable from the line shape of the production.
