标题： Exchange Current Corrections to Neutrino--Nucleus Scattering

摘要： 在假定构成核子的奇夸克形式因子非零的情况下，给出了中微子－原子核横截面的相对论交换流修正。 对于带电电流过程，交换流修正可以使冲量近似结果降低10%，而对于中性电流过程，发现这些修正对核子的核密度以及奇夸克轴向形式因子都很敏感。 讨论了LSND实验确定该形式因子的影响。 显示英文摘要

摘要： Relativistic exchange current corrections to neutrino--nucleus cross sections are presented assuming non--vanishing strange quark form factors for the constituent nucleons. For charged current processes the exchange current corrections can lower the impulse approximation results by 10\% while these corrections are found to be sensitive to both the nuclear density and the strange quark axial form factor of the nucleon for neutral current processes. Implications on the LSND experiment to determine this form factor are discussed.
