Abstract The thermal corrections to the propagator of a loosely bound charm-meson molecule in a pion gas are calculated to next-to-leading order in the heavy-meson expansion using a zero-range effective field theory. Ultraviolet divergences in the ch

We study the time evolution of the numbers of charm mesons after the kinetic freeze-out of the hadron gas produced by a central heavy-ion collision. The $\pi D^\ast \to \pi D^\ast$ reaction rates have $t$-channel singularities that give contributions

The dependence of the production of the $X(3872)$ meson on the hadron multiplicity in $pp$ collisions has been used as evidence against $X$ being a charm-meson molecule. The argument is based in part on the incorrect assumption that the cross section

We calculate the cross section for ${e}^{+}{e}^{\ensuremath{-}}$ annihilation into ${D}^{*0}{\overline{D}}^{0}+\ensuremath{\gamma}$ at center-of-mass energies near the ${D}^{*0}{\overline{D}}^{*0}$ threshold under the assumption that $X(3872)$ is a w

If $X(3872)$ is a weakly bound charm-meson molecule, it can be produced in ${e}^{+}{e}^{\ensuremath{-}}$ annihilation by the creation of ${D}^{*0}{\overline{D}}^{*0}$ from a virtual photon followed by the rescattering of the $P$-wave charm-meson pair

If the double-charm tetraquark meson T+cc(3875) is a loosely bound molecule, it can be produced in high-energy proton-proton collisions by the creation of the charm mesons D∗+D0 at short distances followed by their binding into T+cc. It can also be

The claim that the $X(3872)$ meson cannot be a charm-meson molecule because its prompt production cross section at hadron colliders is too large is based on an upper bound in terms of a cross section for producing charm-meson pairs. Assuming $X$ is s

If the $X(3872)$ is a weakly bound charm-meson molecule, it can be produced by the creation of ${D}^{*0}{\overline{D}}^{0}$ or ${D}^{0}{\overline{D}}^{*0}$ at short distances followed by the formation of the bound state from the charm-meson pair. The
