QCD sum rules for quark-gluon three-body components in the B meson
Tetsuo Nishikawa, Kazuhiro Tanaka
We discuss the QCD sum rule calculation of the heavy-quark effective theory parameters, and , which correspond to matrix elements representing quark-gluon three-body com…

Possible quantum numbers of the pentaquark Θ^+(1540) in QCD sum rules
P. Gubler, D. Jido, T. Kojo +2
The QCD sum rule technique is employed to investigate pentaquark states with strangeness S = +1 and IJ^P = 0,1/2^\pm, 1,1/2^\pm, 0,3/2^\pm, 1,3/2^\pm. Throughout the calculation, e…

Spin-3/2 Pentaquark in QCD Sum Rules
P. Gubler, D. Jido, T. Kojo +2
The QCD sum rule method is formulated for the strangeness +1 pentaquark baryon with isospin I=0 and spin-parity J^P = 3/2^\pm. The spin-3/2 states are considered to be narrower tha…
