Nature of the X(5568) : a critical Laplace sum rule analysis at N2LO

R. Albuquerque, S. Narison, A. Rabemananjara +1

We scrutinize recent QCD spectral sum rules (QSSR) results to lowest order (LO) predicting the masses of the BK molecule and (su)\bar(bd) four-quark states. We improve these result…
