QCD Sum Rule Analysis of Heavy Quarkonium Hybrids
Wei Chen, R. T. Kleiv, T. G. Steele +5
We have studied the charmonium and bottomonium hybrid states with various quantum numbers in QCD sum rules. At leading order in , the two-point correlation functions…
QCD Sum-Rule Interpretation of X(3872) with Mixtures of Hybrid Charmonium and Molecular Currents
Wei Chen, Hong-ying Jin, R. T. Kleiv +3
QCD sum-rules are employed to determine whether the X(3872) can be described as a mixed state that couples to charmonium hybrid and molecular currents.…
Heavy-light diquark masses from QCD sum rules and constituent diquark models of tetraquarks
R. T. Kleiv, T. G. Steele, Ailin Zhang +1
Diquarks with , containing a heavy (charm or bottom) quark and a light quark are investigated using QCD Laplace sum rules. Masses are determined using appr…
Mass Spectrum of Heavy Quarkonium Hybrids
Wei Chen, R. T. Kleiv, T. G. Steele +5
We have extended the calculation of the correlation functions of heavy quarkonium hybrid operators with various quantum numbers to include QCD condensates up to dimension…
