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 quantum numbers. For the…
Study of the system using QCD sum rules
A. Martinez Torres, K. P. Khemchandani, M. Nielsen +2
In this talk I present a study of the system made by using the method of QCD sum rules. Considering isospin and spin projectors, we investigate the different configurations…
Relating currents with and to states
K. P. Khemchandani, A. Martinez Torres, M. Nielsen +1
In this work we study the current with QCD sum rules. We write the correlation function using the general current corresponding to the system and th…
Reanalysis of the reaction and the claim for the resonance
A. Martínez Torres, K. P. Khemchandani, F. S. Navarra +2
In this paper we study the reaction in which the BESIII collaboration has claimed the existence of a resonance, named ,…
Exploring the system within QCD sum rules
A. Martínez Torres, K. P. Khemchandani, M. Nielsen +2
We present a study of the system made by using the method of QCD sum rules to determine the mass of possible resonances generated in the same system. Using isospin and spin…
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…
