论文摘要
拟议的磁化铁热探测器（ICAL）旨在在印度基于中微子观测站（INO）实验室建造，旨在研究大气中微子及其特性，例如振荡参数的精确测量和中微子质量等级。大气中微子与探测器周围的岩石的高能量电流（CC）相互作用产生所谓的“岩石muons”，并与哈德子一起产生。尽管这些事件的强子成分被岩石本身吸收，但岩石宇宙横穿岩石并在检测器中检测到。这些岩石万一的事件只能在向上方向上与宇宙躯干区分开，并可以对振荡参数进行独立的测量。 A simulation study of these events at the ICAL detector shows that, although reduced in significance compared to muons produced in direct CC neutrino interactions with the detector, these events are indeed sensitive to the oscillation parameters, achieving a possible $1σ$ precision of 10\% and 27\% in determining $Δm_{32}^2$ and $\sin^2θ_{23}$, respectively.因此，标准大气中微子分析的结合是ICAL的主要目标，以及这些岩石宇宙事件，将提高这些参数的ICAL的精确度范围。
The proposed magnetized Iron CALorimeter detector (ICAL) to be built in the India-based Neutrino Observatory (INO) laboratory aims to study atmospheric neutrinos and its properties such as precision measurements of oscillation parameters and the neutrino mass hierarchy. High energy charged current (CC) interactions of atmospheric neutrinos with the rock surrounding the detector produce so-called "rock muons" along with hadrons. While the hadron component of these events are absorbed in the rock itself, the rock muons traverse the rock and are detected in the detector. These rock muon events can be distinguished from cosmic muons only in the upward direction and can provide an independent measurement of the oscillation parameters. A simulation study of these events at the ICAL detector shows that, although reduced in significance compared to muons produced in direct CC neutrino interactions with the detector, these events are indeed sensitive to the oscillation parameters, achieving a possible $1σ$ precision of 10\% and 27\% in determining $Δm_{32}^2$ and $\sin^2θ_{23}$, respectively. Hence a combination of the standard atmospheric neutrino analysis which is the main goal of ICAL, with these rock muon events, will improve the precision reach of ICAL for these parameters.
