产生大质量 sterile neutrino 作为温暗物质
摘要
本文已被作者撤回。本文以一个描述弹性散射的错误项作为起点。密度矩阵动力学方程的正确形式推导见例如 A. Dolgov, Yad. Fiz. 33 (1981) 1309; K. Enqvist, K. Kainulainen and J. Maalampi, Nucl. Phys. B 349 (1991) 754; G. Sigl and G. Raffelt, Nucl. Phys. B 406 (1993) 423。使用正确形式的动力学方程时,结果与旧结果 A. Dolgov and S. Hansen, hep-ph/0009083 吻合良好。

备注
This paper has been withdrawn by the authors. This paper started with a wrong term describing elastic scattering. The correct form of the kinetic equations for the density matrix are derived e.g. in A. Dolgov, Yad. Fiz. 33 (1981) 1309; K. Enqvist, K. Kainulainen and J. Maalampi, Nucl. Phys. B 349 (1991) 754; G. Sigl and G. Raffelt, Nucl. Phys. B 406 (1993) 423. When using the correct form of the kinetic equations, the result is in good agreement with old results, A. Dolgov and S. Hansen, hep-ph/0009083
