使用费米实验室的 CCFR 中微子探测器测量中微子-核子和反中微子-核子微分截面，已用于提取运动学区域 0.01 < x < 0.6 和 的初步值。新数据提供了 x < 0.1 区域内 R 的首次测量值。将 x 和 R 的依赖性与基于 QCD 的先前数据拟合进行比较。 QCD 拟合提供了之前未测量过 R 的小 x 区域中的 R 估计值，与新的 CCFR 数据非常一致。
Measurements of neutrino - nucleon and antineutrino - nucleon differential cross sections using the CCFR neutrino detector at Fermilab have been used to extract preliminary values of in the kinematic region 0.01 < x < 0.6 and . The new data provide the first measurements of R in the region x < 0.1. The x and dependence of R is compared with a QCD-based fit to previous data. The QCD fit, which provides an estimate of R in the small-x region where R has not been previously measured, is in good agreement with the new CCFR data.
