The Small Behavior of in the Resummed Approach
Yuichiro Kiyo, Jiro Kodaira, Hiroshi Tochimura
The double logarithmic terms are important to predict precisely the small behavior of the spin structure function . We numerically analyze the evolutio…
Top Pair Production in e^+ e^- and gamma gamma Processes
Michihiro Hori, Yuichiro Kiyo, Jiro Kodaira +2
We analyze spin correlations between top quark and anti-top quark produced at polarized e^+ e^- and gamma gamma colliders. We consider a generic spin basis to find a strong spin co…
Renormalization of the Twist-3 Flavor Singlet Operators in a Covariant Gauge
Jiro Kodaira, Takashi Nasuno, Hiroshi Tochimura +2
We investigate the nucleon's transverse spin-dependent structure function g_2(x, Q^2) in the framework of the operator product expansion and the renormalization group. We construct…
QCD Higher Order Corrections to at Small
Yuichiro Kiyo, Jiro Kodaira, Hiroshi Tochimura
The small behavior of the flavor non-singlet structure function is analysed numerically by taking into account the all-order resummation of terms. We…
Does Leading ln x Resummation Predict the Rise of g_1 at Small x ?
Yuichiro Kiyo, Jiro Kodaira, Hiroshi Tochimura
We numerically analyse the evolution of the flavor non-singlet structure function taking into account the all-order resummation of terms which is expected t…
One-loop correction to the vertex in the collider
Jiro KODAIRA, Hiroshi TOCHIMURA, Yoshiaki YASUI +1
We apply the pinch technique , which is a method to construct the gauge independent off-shell Green's functions, to the process to study the effects of radia…
