论宇宙涡度的手征性
On chirality of the vorticity of the Universe
摘要：
我们在爱因斯坦-嘉当宇宙学中研究了宇宙涡旋的手征性。利用平均自旋密度和爱因斯坦-嘉当方程研究了费米子自旋在宇宙演化中的作用。结果表明，自旋密度的轻马约拉纳中微子作为种子的涡在宇宙演化的早期阶段。它的手征性可以在类空无穷远附近计算。事实证明，宇宙的涡旋具有右手手性。
英文摘要：
We study chirality of the vorticity of the Universe within the Einstein-Cartan cosmology. The role of the spin of fermion species during the evolution of the Universe is studied by averaged spin densities and Einstein-Cartan equations. It is shown that spin density of the light Majorana neutrinos acts as a seed for vorticity at early stages of the evolution of the Universe. Its chirality can be evaluated in the vicinity of the spacelike infinity. It turns out that vorticity of the Universe has right-handed chirality.
