Target Mass Corrections for the Virtual Photon Structure Functions to the Next-to-next-to-leading Order in QCD

Yoshio Kitadono, Ken Sasaki, Takahiro Ueda +1

We investigate target mass effects in the unpolarized virtual photon structure functions $F_{2}^{γ} (x, Q^{2}, P^{2})$ and $F_{L}^{γ} (x, Q^{2}, P^{2})$ in perturbative QCD for the kinematical region $Λ…

Electron-positron annihilation into phi f_{0}(980) and clues for a new 1^{--} resonance

M. Napsuciale, E. Oset, K. Sasaki +1

We study the e^{+}e^{-} to phi pi pi reaction for pions in an isoscalar s-wave which is dominated by loop mechanisms. For kaon loops we start from the conventional RCHPT, but use t…

Polarized Virtual Photon Structure Function in the Next-to-leading Order in QCD

Ken Sasaki, Tsuneo Uematsu

The virtual photon structure function $g_{1}^{γ} (x, Q^{2}, P^{2})$ , which can be obtained in polarized $e^{+} e^{-}$ colliding-beam experiments, is investigated for $Λ^{2} ≪ P^{2} ≪ Q^{2}$ , whe…
