Outer-magnetospheric model for Vela-like pulsars:formation of sub-GeV spectrum

J. Takata, S. Shibata, K. Hirtotani

We investigate the -ray emission from a outer-gap accelerator, which is located in the outer-magnetosphere of a pulsar. The charge depletion from the Goldreich-Julian density ca…

Nuclear Hadronization: Within or Without?

B. Z. Kopeliovich, J. Nemchik, E. Predazzi +1

Nuclei are unique analyzers for the early stage of the space-time development of hadronization. DIS at medium energies is especially suitable for this task being sensitive to hadro…
