Abstract

We explore the consequences of heavy quark spin symmetry for the charmed meson-antimeson system in a contact-range (or pionless) effective field theory. As a trivial consequence, we theorize the existence of a heavy quark spin symmetry partner of the X(3872), with J^PC=2⁺⁺, which we call X(4012) in reference to its predicted mass. If we additionally assume that the X(3915) is a 0⁺⁺ heavy spin symmetry partner of the X(3872), we end up predicting a total of six D^(*)D^(*) molecular states. We also discuss the error induced by higher order effects such as finite heavy quark mass corrections, pion exchanges and coupled channels, allowing us to estimate the expected theoretical uncertainties in the position of these new states.
