准弹性散射的纠缠与π介子的产生

Entanglement of Quasielastic Scattering and Pion Production

Ulrich Mosel, Olga Lalakulich, Tina Leitner

摘要:

提取中微子振荡参数需要从强子末态的观测中确定中微子的能量。在这里,我们讨论了正在进行的实验MiniBooNE和T2K与这种能量重建的困难。我们指出,一个下限的重建能量的不确定性,从费米运动单独的金额约为15%。非常不同的基本过程的纠缠,在这种情况下,准弹性散射和π介子的产生,在实际的可观测量导致相当大的误差。我们讨论的灵敏度的能量重建的检测技术和实验接受。我们还计算了T2K实验中由于中性π介子产生而导致的电子出现的错误识别截面。

英文摘要:

The extraction of neutrino oscillation parameters requires the determination of the neutrino energy from observations of the hadronic final state. Here we discuss the difficulties connected with this energy reconstruction for the ongoing experiments MiniBooNE and T2K. We point out that a lower limit to the uncertainty in the reconstructed energy from Fermi motion alone amounts to about 15%. The entanglement of very different elementary processes, in this case quasielastic scattering and pion production, in the actual observables leads to considerably larger errors. We discuss the sensitivity of the energy reconstruction to detection techniques and experimental acceptances. We also calculate the misidentification cross section for electron appearance in the T2K experiment due to neutral pion production.
