描述低x区核子结构函数的双分量模型

Two component model for a description of nucleon structure functions in low-x region

E. V. Bugaev, B. V. Mangazeev

摘要:

本文简要介绍了基于广义矢量占优和色偶极方法描述低x区电磁核子结构函数的双分量模型。该模型考虑了介子-核子散射中的非对角跃迁,并考虑了ρ族介子的质量谱在平方质量上是等距的。在模型中引入了特殊的截止因子,以排除窄qq对情况下的γ-qq-V跃迁。对于模型的颜色偶极子部分,使用众所周知的FKS参数化。

英文摘要:

Two component model for a description of the electromagnetic nucleon structure functions in low-x region, based on generalized vector dominance and color dipole approaches is briefly described. The model operates with the mesons of rho-family having the mass spectrum which is equidistant on square mass and takes into account the nondiagonal transitions in meson-nucleon scattering. The special cut-off factors are introduced in the model, to exclude the gamma-qq-V transitions in the case of the narrow qq-pairs. For the color dipole part of the model the well known FKS-parameterization is used.
