我们提出了两种类型的独家魅力生产反应的截面计算:准弹性过程。nu.. N ..-->.. .. mu../ sup -/(C/sub 0/,C/sub 1/,C/sub 1/*)和单赝标介子产生过程。nu.. N ..-->.. .. mu../ sup -/K(C/sub 0/,C/sub 1/)和anti .. nu.. N ..-->.. .. mu../ sup +/ anti D(. lambda..,.. sigma..)。通过一组合理的假设,我们发现这些排他性通道的横截面与包容性非魅力横截面的比率约为。4%的中微子和大约。3%的反中微子。(AIP)
We present calculations of the cross sections for two types of exclusive charm-production reactions: the quasi-elastic processes ..nu..N ..-->.. ..mu../sup -/(C/sub 0/,C/sub 1/,C/sub 1/*) and the single-pseudoscalar-meson production processes ..nu..N ..-->.. ..mu../sup -/K(C/sub 0/,C/sub 1/) and anti ..nu..N ..-->.. ..mu../sup +/ anti D(..lambda..,..sigma..). With a set of reasonable assumptions we find that the ratio of the cross section for these exclusive channels to the inclusive noncharm cross section is approx. 4% for neutrinos and approx. 3% for antineutrinos.
