摘要
介绍了在χ2假设检验中引入本底和系统误差的方法,并通过最大化混合角θ13的测量敏感度对反应堆中微子实验的基线长度进行优化.考察了对基线有影响的几个因素,包括振荡效应,统计误差,系统误差,本底等.尽管实验条件可能很不相同,最优基线仍可被确定在一个较小的范围内.
We have applied the X2-minimization technique that takes backgrounds and systematic uncertainties into account to optimize the baseline of the reactor neutrino experiments designed for determining the mixing angle θ13 of neutrino. The effect of oscillation, systematic errors, statistic errors and backgrounds in the optimization are investigated. Although the experimental conditions may be very different, the optimal baseline is constrained in a narrow range.
