Outline of Final Research Achievements

In this project, we have studied particle production from synchrotron radiation of protons and electrons in strong magnetic fields. Here, we have performed the relativistic quantum calculation, which has not been done so much, by considering particle transitions between two Landau levels. Then, we can correctly discuss details of observables which has not been calculated. Particularly, it is the first in the world to establish the approach to calculate particle productions in TeV energy region in the relativistic quantum framework. In actual, we have calculated production of high energy pion, axion and neutrino-antineutrino pair in highly magnetized neutron stars, and have studied generation mechanism of high energy cosmic rays and characteristic cooling mechanism of them.

Academic Significance and Societal Importance of the Research Achievements

非常に強い磁場を持つ中性子星においては,電子,陽子等の粒子が磁場の力により螺旋運動(シンクロトロン運動)を行い,光子等の粒子を放出(シンクロトロン放射)する。そして,その放出粒子を観測すれば,磁気構造について多くの情報が得られると期待されている。しかしながら,従来の理論計算は半古典論のもので,結果の正確性には疑問がもたれていた。本研究において,我々は相対論的量子論により正確な理論計算法を確立することに成功した。本研究の成果により,中性子星等の構造についてより定量的な詳しい議論が可能となり,天文学以外のシンクロトロン放射に関する理論計算の改良にも貢献するであろう。
