碳原子准弹性散射核效应的直接提取

Direct extraction of nuclear effects in quasielastic scattering on carbon

Callum Wilkinson, Kevin S. McFarland

摘要:

在当前和未来的中微子振荡实验中,中微子反应的核效应将是一个重要的复杂因素,这些实验都是为了精确测量中微子的味跃迁。这些核效应的计算由于缺乏比较中微子在自由核子上的反应和中微子在原子核上的反应的实验数据而受到阻碍。我们提出了一种新的技术,比较中微子和反中微子带电电流准弹性散射碳氢化合物提取的截面比的反中微子带电电流弹性反应的自由质子上的带电电流准弹性反应的质子约束在碳核的结果。这种核效应的测量与模型进行了比较。

英文摘要:

Nuclear effects on neutrino reactions are expected to be a significant complication in current and future neutrino oscillation experiments seeking precision measurements of neutrino flavor transitions. Calculations of these nuclear effects are hampered by a lack of experimental data comparing neutrino reactions on free nucleons to neutrino reactions on nuclei. We present results from a novel technique that compares neutrino and antineutrino charged current quasielastic scattering on hydrocarbons to extract a cross section ratio of antineutrino charged current elastic reactions on free protons to charged current quasielastic reactions on the protons bound in a carbon nucleus. This measurement of nuclear effects is compared to models.
