Heavy quark spin symmetry and SU(3)-flavour partners of the image

In this work, an Effective Field Theory (EFT) incorporating light SU(3)-flavour and heavy quark spin symmetries is used to describe charmed meson–antimeson bound states. At Lowest Order (LO), this means that only contact range interactions among the heavy meson and antimeson fields are involved. Besides, the isospin violating decays of the image will be used to constrain the interaction between the D and a image mesons in the isovector channel. Finally, assuming that the image and image resonances are image and image molecular states, we can determine the four Low Energy Constants (LECs) of the EFT that appear at LO and, therefore, the full spectrum of molecular states with isospin image, image and 1.
