Selected topics on parton distribution functions
M. Hirai, H. Kawamura, S. Kumano +1
We report recent studies on structure functions of the nucleon and nuclei. First, clustering effects are investigated in the structure function F_2 of Be-9 for explaining an unusua…
Numerical solution of evolution equations for fragmentation functions
M. Hirai, S. Kumano
Semi-inclusive hadron-production processes are becoming important in high-energy hadron reactions. They are used for investigating properties of quark-hadron matters in heavy-ion c…
Recent progress on nuclear parton distribution functions
M. Hirai, S. Kumano, K. Saito
We report current status of global analyses on nuclear parton distribution functions (NPDFs). The optimum NPDFs are determined by analyzing high-energy nuclear reaction data. Due t…
Clustering effects for explaining an anomalous JLab result on the Be-9 structure function
M. Hirai, S. Kumano, K. Saito +1
An anomalous nuclear modification was reported by JLab measurements on the beryllium-9 structure function F_2. It is unexpected in the sense that a nuclear modification slope is to…
