So, just like in deuteron, I assume that pi(1800) is a molecule and get \lambda_R. But once I do, I can do things for other mesons… @Jordy_de_Vries So I use the formalism only to establish that there is a pole, I.e. a bound state @Jordy_de_Vries But I don’t think that this system is as fine-tuned as a deuteron or an X(3872)",https://arxiv.org/abs/2204.11269,"Experimental searches for pure glueball states have proven challenging and so far yielded no results. This is believed to occur because glueballs mix with the ordinary $q\bar q$ states with the same quantum numbers. We will discuss an alternative mechanism, the formation of the glueball-meson molecular states. We will argue that the wave functions of already observed excited meson states may contain a significant part due to such molecular states. We discuss the phenomenology of glueball molecules and comment on a possible charmless component of the $XYZ$ states. ",Glueball molecules,4,"['A new paper!
