μ子和电子中微子准弹性截面的差异

Differences in Quasi-Elastic Cross-Sections of Muon and Electron Neutrinos

Melanie Day, Kevin S. McFarland

摘要:

加速器中微子振荡实验旨在精确测量μ子(反)中微子到电子(反)中微子的中微子味振荡,以确定中微子的质量等级,寻找中微子振荡中的CP破坏。这些实验目前是用能量接近1 GeV的μ介子中微子束进行的,其中带电准弹性相互作用nu+n \rightarrow(l^-)+p和反nu +p \rightarrow(l^+)+n主导信号反应。我们研究了μ子、电子中微子和反中微子的准弹性截面之间的差异,并估计了这些差异的不确定性。

英文摘要:

Accelerator neutrino oscillation experiments seek to make precision measurements of the neutrino flavor oscillations muon (anti)neutrino to electron (anti)neutrino in order to determine the mass hierarchy of neutrinos and to search for CP violation in neutrino oscillations. These experiments are currently performed with beams of muon neutrinos at energies near 1 GeV where the charged-current quasi-elastic interactions nu+n\rightarrow(l^-)+p and anti-nu+p\rightarrow(l^+)+n dominate the signal reactions. We examine the difference between the quasi-elastic cross-sections for muon and electron neutrinos and anti-neutrinos and estimate the uncertainties on these differences.
