用MINOS研究中微子振荡

Neutrino Oscillation Studies with MINOS

Patricia Vahle

摘要:

MINOS实验在两个探测器站观测主注入器加速器产生的NuMI光束,一个距离中微子产生目标1公里,另一个距离中微子产生目标735公里。从中微子在两个探测器之间飞行消失的过程中,我们测量了中微子振荡参数$Δm_{23}^2$和$\sin^2(2θ_{23})$,并更新了我们以前发表的结果。此外,我们还寻找了不与弱相互作用耦合的其他轻中微子族的证据。最后,我们讨论的状态,我们的搜索$ν_{e}$的外观,预期的效果,如果混合角$θ_{13}$是非零和所需的,如果目标的CP破坏在中微子部门被观察到。

英文摘要:

The MINOS experiment observes the NuMI beam produced by the Main Injector accelerator at two detector stations, one 1 km and the other 735 km from the neutrino production target. From the disappearance of neutrinos in flight between the two detectors, we measure the neutrino oscillation parameters $Δm_{23}^2$ and $\sin^2(2θ_{23})$ and update our previously published result. Additionally, we have searched for evidence of additional light neutrino families which do not couple to the weak interaction. Finally, we discuss the status of our search for the appearance of $ν_{e}$, an effect expected if the mixing angle $θ_{13}$ is non-zero and required if the goal of CP violation in the neutrino sector is to be observed.
