Antishadowing in K+-nucleus Scattering
-
摘要: 核散射中罕见的反阴影效应在K~+介子与核的散射中出现了,1988~1990年BNL的系列实验确认了这一反常现象,然而,在核子层次上对此所作的各种理论解释几乎均告失败,因此人们不得不到夸克层次上寻找原因。 Unusual antishadowing appeared in K~+-nucleus scattering, which was reconfirmed byBrookhaven experiments in 1988~1991. Almost all of the conventional explanations of this effectat nucleon level are not successful. One has to search for new interpretations at quark level.Abstract: Unusual antishadowing appeared in K~+-nucleus scattering, which was reconfirmed byBrookhaven experiments in 1988~1991.
