LHC超相对论超中微子和超中微子-反中微子振荡
Ultrarelativistic sneutrinos at the LHC and sneutrino-antisneutrino oscillation
摘要：
中微子-反中微子振荡是寻找LHC中轻子数破坏（$ΔL = 2$）的一个非常有用的探测器。在这里，我们讨论了提升因子$γ$和行进距离$L$对振荡概率的影响。我们证明，这两个参数可以显着改变的振荡的概率时，sneutrinos是超相对论性的，并有一个非常小的总衰变宽度。我们提出了一个方案，这些要求得到满足，并产生有趣的信号在大型强子对撞机，即使是一个质量分裂$Δm$小到$10^{-14}$ GeV之间的中微子质量本征态。
英文摘要：
Sneutrino-antisneutrino oscillation can be a very useful probe to look for signatures of lepton number violation ($ΔL = 2$) at the LHC. Here, we discuss the effect of the boost factor $γ$ and the travelling distance $L$ on the probability of the oscillation. We demonstrate that these two parameters can significantly alter the probability of the oscillation when the sneutrinos are ultrarelativistic and have a very small total decay width. We propose a scenario where these requirements are fulfilled and which produces interesting signals at the LHC even for a mass splitting $Δm$ as small as $10^{-14}$ GeV between the sneutrino mass eigenstates.
