Primary proton spectrum between 200 TeV and 1000 TeV observed with the Tibet burst detector and air shower array
M. Amenomori, S. Ayabe, Caidong
Since 1996, a hybrid experiment consisting of the emulsion chamber and burst detector array and the Tibet-II air-shower array has been operated at Yangbajing (4300 m above sea leve…
Polarized and Unpolarized Structures of the Virtual Photon
Ken Sasaki, Tsuneo Uematsu
We discuss the structure functions and the parton distributions in the virtual photon target, both polarized and unpolarized, beyond the leading order in QCD. We study the factoriz…
Broad-Band Spectral Energy Distributions of Active Galactic Nuclei from an Accretion Disk with Advective Coronal Flow
Toshihiro Kawaguchi, Toshiya Shimura, Shin Mineshige
We construct a disk-corona model which accounts for the optical-to-X-ray spectral properties of Seyfert nuclei and QSOs. We study emission spectrum emerging from a vertical disk-co…
A study of the shadowing of galactic cosmic rays by the sun in a quiet phase of solar activity with the Tibet air shower array
M. Amenomori, S. Ayabe, Caidong
We have shown that the Sun's shadow by high energy cosmic rays moves year by year and its behavior is correlated with a time variation of the large-scale structure of the solar and…
Measurement of air shower cores to study the cosmic ray composition in the knee energy region
M. Amenomori, S. Ayabe, Caidong
Since 1996, a hybrid experiment consisting of an emulsion chamber and a burst detector array and the Tibet-II air shower array has been operated at Yangbajing (4300 m above sea lev…
Factorization Scheme and Parton Distributions in the Polarized Virtual Photon Target
Ken Sasaki, Tsuneo Uematsu
We investigate spin-dependent parton distributions in the polarized virtual photon target in perturbative QCD up to the next-to-leading order (NLO). In the case $Λ^2 \ll P^2 \ll Q^…
