BFKL Pomeron演算:核-核散射方程的饱和域解

BFKL Pomeron calculus: solution to equations for nucleus-nucleus scattering in the saturation domain

Carlos Contreras, Eugene Levin, Rodrigo Meneses

摘要:

本文用Braun提出的BFKL波密子演算求解核-核散射方程。我们发现这些解决方案在高能量解析以及数值在整个区域内的饱和区域的能量。半经典近似用于选择寄生解的无限集合。计算了高能核-核截面,并与Glauber-Gribov方法进行了比较。结果表明,精确公式给出的估计值与基于Glauber-Gribov公式的估计值非常接近,这对实际应用具有重要意义

英文摘要:

In this paper we solve the equation for nucleus-nucleus scattering in the BFKL Pomeron calculus, suggested by Braun. We find these solutions analytically at high energies as well as numerically in the entire region of energies inside the saturation region. The semi-classical approximation is used to select out the infinite set of the parasite solutions. The nucleus-nucleus cross sections at high energy are estimated and compared with the Glauber-Gribov approach. It turns out that the exact formula gives the estimates that are very close to the ones based on Glauber-Gribov formula which is important for the practical applications
