1-- and 0++ Four-Quarks and Molecules from QCD Spectral Sum Rules

R. M. Albuquerque, F. Fanomezana, S. Narison +1

We estimate the masses of the 1-- heavy four-quark and molecule states by combining exponential Laplace (LSR) and finite energy (FESR) sum rules known perturbatively to lowest orde…

Y(4260) as a mixed charmonium-tetraquark state

J. M. Dias, R. M. Albuquerque, M. Nielsen +1

Using the QCD sum rule approach we study the Y(4260) state assuming that it can be described by a mixed charmonium-tetraquark current with $J^{P C} = 1^{--}$ quantum numbers. For the…

Exotic B_c-like molecules in QCD Sum Rules

Raphael M. Albuquerque, Xiang Liu, Marina Nielsen

We use the QCD sum rules to study possible $B_{c}$ -like molecular states. We consider isoscalar $J^{P} = 0^{+}$ and $J^{P} = 1^{+} D^{(*)} B^{(*)}$ molecular currents. We consider the c…
