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…
The meson as a tetraquark state
M. E. Bracco, S. H. Lee, M. Nielsen +1
We test the validity of the QCD sum rules applied to the meson , by considering a diquark-antidiquark type of current with and with . We find…
Are and the Roper resonance diquark-diquark-antiquark states?
R. D. Matheus, F. S. Navarra, M. Nielsen +2
We consider a current in the QCD sum rule framework to study the mass of the recently observed pentaquark state , obtaining good agreement with the exper…
symmetry restoration in QCD with flavors
Su H. Lee, T. Hatsuda
Recently, there have been reports that the chirally restored phase of QCD is effectively symmetric under rather than . We supplement t…
Transverse Quark Distribution in Mesons - QCD Sum Rule Approach -
Su H. Lee, T. Hatsuda, G. A. Miller
QCD sum rules are used to compute the first few moments of the mesonic quark momentum. Transverse, longitudinal and mixed transverse-longitudinal components are examined. The trans…
