Emission of High-Energy Gamma-rays and Neutrinos from Gamma-Ray Bursts are investigated with the support of this program. Especially, I could evaluate the emissivity of TeV gamma-rays from Gamma-Ray Bursts with a help of the toolkit GEANT4, which enables me to estimate the emissivity correctly. Thanks to this program, my study has been the most reliable one in the world. The result of my research is now used as an template of high-energy GRB neutrino background by IceCube team, and the GRB neutrinos are being expected to be detected in the near future.

在该计划的支持下，对伽马射线爆发中高能伽马射线和中微子的发射进行了研究。特别是，我可以借助工具包 GEANT4 来评估来自伽马射线暴的 TeV 伽马射线的发射率，这使我能够正确估计发射率。感谢这个项目，我的研究成为世界上最可靠的研究。我的研究成果现已被IceCube团队用作高能GRB中微子背景的模板，预计在不久的将来能够探测到GRB中微子。
