下一代液态氩TPC探测器沿J-PARC中微子束的中微子振荡

Neutrino Oscillations With A Next Generation Liquid Argon TPC Detector in Kamioka or Korea Along The J-PARC Neutrino Beam

A. Meregaglia, A. Rubbia

摘要:

沿着东海产生的J-PARC中微子束进行可能的T2 K以外的下一代长基线实验的"基线设置“假定有两个非常大的深地下水切伦科夫成像探测器,每个探测器的基准约为300千吨,一个位于韩国,另一个位于神冈,但离轴角相同。在本文中,我们考虑的物理性能类似的设置,但与一个单一的和更小的,远探测器,可能在浅的深度,由100千吨的下一代液体氩时间投影室。探测器的潜在位置可能在神冈地区($L\sim 295$公里)或朝鲜东部海岸($L\sim 1025$公里),这取决于T2 K实验的结果。在韩国,离轴角可以是SuperKamiokande中的$2.5^{o} \sim 3^{o}$,或者是提供伪宽带波束条件的$\sim 1^{o}$。

英文摘要:

The ``baseline setup'' for a possible, beyond T2K, next generation long baseline experiment along the J-PARC neutrino beam produced at Tokai, assumes two very large deep-underground Water Cerenkov imaging detectors of about 300 kton fiducial each, located one in Korea and the other in Kamioka but at the same off-axis angle. In this paper, we consider the physics performance of a similar setup but with a single and smaller, far detector, possibly at shallow depth, composed of a 100 kton next generation liquid Argon Time Projection Chamber. The potential location of the detector could be in the Kamioka area ($L\sim 295$ km) or on the Eastern Korean coast ($L\sim 1025$ km), depending on the results of the T2K experiment. In Korea the off-axis angle could be either $2.5^{o} \sim 3^{o}$ as in SuperKamiokande, or $\sim 1^{o}$ as to offer pseudo-wide-band beam conditions.
