Exotic Hadron in Pole-dominated QCD Sum Rules
Toru Kojo, Daisuke Jido, Arata Hayashigaki
We study pentaquark in the QCD sum rules emphasizing that we can not extract any properties of the pentaquark outside of the Borel window. To find the appropria…
Proton and anti-proton production in the forward region of d+Au collisions at RHIC from the color glass condensate
Arata Hayashigaki
The power-law tail of high-pt pi^\pm spectra observed in forward d+Au collisions at RHIC can be attributed to the power-law decrease of the dipole forward scattering amplitude appe…
Pentaquark state in pole-dominated QCD sum rules
Toru Kojo, Arata Hayashigaki, Daisuke Jido
We propose a new approach in QCD sum rules applied for exotic hadrons with a number of quarks, exemplifying the pentaquark Theta^{+} (I=0,J=1/2) in the Borel sum rule. Our approach…
Charmed-meson spectroscopy in QCD sum rule
A. Hayashigaki, K. Terasaki
We elaborate masses of open-charm mesons (c\bar{d} and c\bar{s}) with J^P=0^-,1^-,0^+,1^+ from a viewpoint of ordinary light-heavy systems in the analysis of standard Borel-transfo…
Transverse quark motion inside charmonia in diffractive photo- and electroproductions
Arata Hayashigaki, Kazuhiro Tanaka
We reexamine the Fermi motion effects on the diffractive photo- and electroproductions of heavy vector-mesons, J/psi and psi', off a nucleon in the leading ln(Q^2/Lambda_QCD^2) app…
Investigation of the color-dipole structure in diffractive t-slopes of charmonia photo- and electroproductions
Arata Hayashigaki, Katsuhiko Suzuki
The diffractive t-slope, B_V, of elastic charmonia (V=J/psi, psi') photo- and leptoproductions off a nucleon is studied at low |t| (< 1 GeV^2) in the leading logarithmic approximat…
