and molecules at N2LO from QSSR

We estimate the and molecules masses and couplings using QCD spectral sum rules (QSSR) known perturbatively to N2LO of PT series and including the contributions of non-perturabtive condensates up to the dimension-eight. Our results improve earlier LO results obtained from QSSR in the current literature. We obtain which is heavier than the experimental candidates Y(4260), Y(4360), Y(4660) suggesting that they cannot be pure molecule states. We predict to be tested in B–factory experiments.
