X(3872) and Bound State Problem of D0(D)*0((D)0D*0)

摘要

We have performed a dynamical calculation of the bound state problem of D0(D)*0 by considering the pion and sigma meson exchange potential.Our preliminary analysis disfavors the molecular interpretation of X(3872) if we use the experimental D* Dπ coupling constant g=0.59 and a reasonable cutoff around 1 GeV,which is the typical hadronic scale.In contrast,there probably exists a loosely bound S-wave B (-B)* molecular state.Such a molecular state would be rather stable since its dominant decay mode is the radiative decay through B*→Bγ.
