酉化BFKL方程的核遮蔽与反遮蔽
Nuclear Shadowing and Antishadowing in a Unitarized BFKL Equation
摘要：
用一个归一化的BFKL方程解释了核遮蔽和反遮蔽效应。核部分子分布的$Q^2$ -和$x$ -变化的详细的未整合的胶子分布的水平的基础上。特别地，研究了核靶中非积分胶子分布在饱和极限附近的渐近行为。如果参数由自由质子的数据固定，我们在核靶中的结果对输入分布不敏感。
英文摘要：
The nuclear shadowing and antishadowing effects are explained by a unitarized BFKL equation. The $Q^2$- and $x$-variations of the nuclear parton distributions are detailed based on the level of the unintegrated gluon distribution. In particular, the asymptotical behavior of the unintegrated gluon distribution near the saturation limit in nuclear targets is studied. Our results in the nuclear targets are insensitive to the input distributions if the parameters are fixed by the data of a free proton.
