${\bar{D}}^{\ast }D$ and ${\bar{B}}^{\ast }B(1^{++})$ molecules at N2LO from QSSR

F. Fanomezana, S. Narison, A. Rabemananjara

We use QCD spectral sum rules (QSSR) and the factorization properties of molecule currents to estimate the masses and couplings of the ${\bar{D}}^{\ast }D$ and ${\bar{B}}^{\ast }B(1^{++})$ molecule…
