CHARM 2013: X(4260) as a Mixed Charmonium-Tetraquark State

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

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

Y(3940) as a Mixed Charmonium-Molecule State

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

Using the QCD sum rules approach we study the mass and decay width of the channel $J / ψ + ω$ for the $Y (3940)$ state. We assume that it can be described by a mixed charmonium-molecul…

QCD Sum Rule Study for a Possible Charmed Pentaquark Θc(3250)

R. M. Albuquerque, S. H. Lee, M. Nielsen

We use QCD sum rules to study the possible existence of a Θc(3250) charmed pentaquark. We consider the contributions of condensates up to dimension-10 and work at leading order in…
