BFKL ansatz for BK equation in conformal basis

S. Bondarenko, A. Prygarin

摘要:

对保角基下的BK方程进行了研究和分析。结果表明,在高能量的因式分解的坐标和快度的依赖性应持有。这允许显著简化所讨论的方程的形式。本文提出并分析了高能BK方程解的解析表达式。该解析解在低能时满足初始条件,在高能极限时不依赖于快度和初始条件。讨论了末态快度不太大的情况,并研究了末态快度大小之间的过渡区的性质。

英文摘要:

The BK equation in the conformal basis is considered and analyzed. It is shown that at high energy a factorization of the coordinate and rapidity dependence should hold. This allows to simplify significantly the from of the equation under discussion. An analytical ansatz for the solution to the BK equation at high energies is proposed and analyzed. This analytical ansatz satisfies the initial condition at low energy and does not depend on both rapidity and the initial condition in the high energy limit. The case of the final rapidity being not too large is discussed and the properties of the transition region between small and large final rapidities have been studied.
