Charmed Hadron Production in Polarized pp Reactions as a Probe of Polarized Gluons in the Proton
Toshiyuki Morii, Kazumasa Ohkuma
To probe the behavior of polarized gluons in the proton, we propose the charmed hadron, such as Lambda_c and D^*, production in the forthcoming RHIC experiments. We found that the…
Twist-3 effects for polarized virtual photon structure function
Ken Sasaki
We investigate twist-3 effects in the polarized virtual photon. The structure function , which exists only for the virtual photon target and can be measured in future polari…
Charmed Hadron Production in Polarized pp Collisions
Toshiyuki Morii, Kazumasa Ohkuma
To extract information about polarized gluons in the proton, production of charmed hadrons, in particular, Λ_c^+ baryon in pp collisions was studied. We calculated the transverse m…
Limit theorems and absorption problems for quantum random walks in one dimension
Norio Konno
In this paper we consider limit theorems, symmetry of distribution, and absorption problems for two types of one-dimensional quantum random walks determined by 2 times 2 unitary ma…
Multifractal analysis of fluid particle accelerations in turbulence
T. Arimitsu, N. Arimitsu
The probability density function (PDF) of accelerations in turbulence is derived analytically with the help of the multifractal analysis based on generalized entropy, i.e., the Tsa…
Observation of Multi-Tev Diffuse Gamma Rays from the Galactic Plane with the Tibet Air Shower Array
M. Amenomori et al.
Data from the Tibet-III air shower array (with energies around 3 TeV) and from the Tibet-II array (with energies around 10 TeV) have been searched for diffuse gamma rays from the G…
