Non-perturbative pion dynamics for the X(3872)

Non-perturbative pion dynamics for the X(3872)

We discuss the role of non-perturbative pion dynamics on the near-threshold resonant X(3872) charmonium state, which is assumed to be an S-wave DD̄* bound system. We calculate the contribution to the width of the X(3872) from the DD̄π intermediate state treated non-perturbatively and compare it with...
