Measurement of the Y-Distributions in Antineutrino Inelastic Interactions with Nucleons

摘要

Preliminary results are presented on the y-distributions in anti nu reactions obtained in a recent high acceptance counter experiment (E310) at Fermilab. The data show an energy dependence of dN/dy on E-/sub nu/ from 10 to 200 GeV. The y-distributions at low values of x are much flatter than at higher x, implying a different density of antiquarks at different x. A summary of world data on y-distributions is also presented. 10 references. (ERA citation 04:043947)
