结合大亚湾反应堆装置解决LBL实验中的八度简并问题

Resolving Octant Degeneracy at LBL experiment by combining Daya Bay Reactor Setup

Kalpana Bora, Debajyoti Dutta

摘要:

长基线实验(LBL)有望成为研究中微子相关问题的一个非常强大的实验装置。一些正在进行和计划中的LBL和中基线实验是-T2 K,MINOS,NOvA,LBNE,LBNO等,但由于存在一些参数简并,如八分圆简并,长基线实验被削弱。在本工作中,我们首先在LBL实验中发现了八分圆简并的存在,然后将其与大亚湾反应堆实验相结合,在不同的CP破坏相位下。我们表明,八分圆简并在LBNE可以完全解决这个建议。

英文摘要:

Long baseline Experiment (LBL) have promised to be a very powerful experimental set up to study various issues related to Neutrinos. Some ongoing and planned LBL and medium baseline experiments are - T2K, MINOS, NOvA, LBNE, LBNO etc. But the long baseline experiments are crippled due to presence of some parameter degeneracies, like the Octant degeneracy. In this work, we first show the presence of Octant degeneracy in LBL experiments, and then combine it with Daya Bay Reactor experiment, at different values of CP violation phase. We show that the Octant degeneracy in LBNE can be resolved completely with this proposal.
