使用安装在费米实验室宽带中微子束上的混合乳化液光谱仪，我们在目标的基准体积中发现了总共3855个中微子相互作用。对于在这些相互作用中发现的122个粲粒子衰变，我们给出了x、y、粲-介子角投影、费曼- x和碎片化z的分布。我们发现核子海中的奇异夸克数是下夸克数的4.2±2.1±2.6%。
Using a hybrid emulsion spectrometer installed in the Fermilab wide-band neutrino beam, we located a total of 3855 neutrino interactions in the fiducial volume of our target. For 122 charmed-particle decays found in these interactions, we present distributions of x,y, charm-muon angular projection, Feynman-X, and the fragmentation Z. We find that the number of strange quarks in the nucleon sea is 4.2±2.1±2.6% of the number of down quarks.
