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) over bar (()*()) 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.", optnote="WOS:000308869400013", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=1162), last updated on Thu, 18 Oct 2012 10:16:58 +0000", issn="1550-7998", doi="10.1103/PhysRevD.86.056004", opturl="http://arxiv.org/abs/1204.2790", opturl="https://doi.org/10.1103/PhysRevD.86.056004", archivePrefix="arXiv", eprint="1204.2790", language="English" }
