反暗物质:镜像世界的一张隐藏的面孔

Anti-dark matter: a hidden face of mirror world

Zurab Berezhiani

摘要:

B和L破坏了普通粒子与它们的孪生粒子在假想镜像世界中的相互作用,可以在两个世界中共同产生相当数量的重子不对称性,$Ω'_B/Ω_B \sim 5$左右。另一方面,同样的相互作用引起两个扇区的中性粒子之间的振荡现象,例如将镜像中子转换为我们的反中子。这些振荡是环境依赖的,可以有迷人的物理后果。

英文摘要:

B and L violating interactions of ordinary particles with their twin particles from hypothetical mirror world can co-generate baryon asymmetries in both worlds in comparable amounts, $Ω'_B/Ω_B \sim 5$ or so. On the other hand, the same interactions induce the oscillation phenomena between the neutral particles of two sectors which convert e.g. mirror neutrons into our antineutrons. These oscillations are environment dependent and can have fascinating physical consequences.
