Abstract |
We perform a theoretical study of the B & thorn;-* D & thorn;D-K & thorn;, B0-* D & thorn;D-K0 and Ab-* D & thorn;D-A reactions by looking at the production mechanisms, with special emphasis in the final state interaction of the charmed mesons, which gives rise to the X(3930), coupling strongly to DS D & strns;S, and another state that we call X(3700), coupling strongly to DD & strns; that qualifies as a DD & strns; bound state. The combined study of all these reactions shows that the final state interaction responsible for the production of these resonances is more important in the B & thorn;-* D & thorn;D-K & thorn; reaction than in the Ab-* D & thorn;D-A one. We have taken this into account and shown that normalizing the D & thorn;D-mass distributions to the same value at the peak of the psi(3770) production, the two mass distributions are quite different in a range of 10 MeV above the D & thorn;D-threshold, with a value about an order of magnitude bigger for the B & thorn;-* D & thorn;D-K & thorn; reaction than for the Ab-* D & thorn;D-A one. The D & thorn;D-mass distribution by itself also shows an enhancement of about one order of magnitude in the presence of the X(3700) with respect to a calculation where this resonance is absent. We make a call to measure these magnitudes in the coming LHCb upgrades, which would bring great support to the existence of the bound D & thorn;D-state. |
