偏振辐射与地球及其他地区生物同手性的出现
Polarized radiation and the Emergence of Biological Homochirality on Earth and Beyond
摘要：
有人提出，自旋极化宇宙辐射可以诱导螺旋生物聚合物的不对称变化，这可能是生物同手性出现的原因。弱相互作用中的宇称破缺对宇宙线簇射中的极化输运有直接的影响。在本文中，我们表明，μ子保持其极化的能量，他们可以启动对映选择性诱变。因此，μ子最有可能成功地建立粒子物理学标准模型中对称性破缺与生物体中对称性破缺之间的联系。我们计算的辐射剂量沉积在各种主要目标的初级和次级宇宙射线的搜索生命在太阳系：火星，金星，泰坦，冰冷的卫星和微行星，并讨论了建议的对映体选择性诱变的影响是驱动程序的同手性。地球是不寻常的，因为自旋极化的μ子主导了它表面的宇宙辐射。
英文摘要：
It has been proposed that spin-polarized cosmic radiation can induce asymmetric changes in helical biopolymers that may account for the emergence of biological homochirality. The parity violation in the weak interaction has direct consequences on the transport of polarization in cosmic ray showers. In this paper, we show that muons retain their polarization down to energies at which they can initiate enantioselective mutagenesis. Therefore, muons are most likely to succeed in establishing the connection between broken symmetries in the standard model of particle physics and that found in living organisms. We calculate the radiation doses deposited by primary and secondary cosmic rays at various prime targets for the searches of life in the solar system: Mars, Venus, Titan, icy moons and planetesimals, and discuss the implications for the enantioselective mutagenesis proposed as to be the driver of homochiralization. Earth is unusual in that spin-polarized muons dominate the cosmic radiation at its surface.
