Solving The High Energy Evolution Equation Including Running Coupling Corrections

摘要: We study the solution of nonlinear Balitsky-Kovchegov evolution equation with recently calculated running coupling corrections [I. I. Balitsky, Phys. Rev. D 75, 014001 (2007). and Y. Kovchegov H. Weigert, Nucl. A784, 188 (2007).]. Performing a numerical we confirm earlier result Albacete et al. [Phys. 71, 014003 (2005).] (obtained by exploring several possible scales for coupling) that high energy leads to universal scaling behavior dipole-nucleus scattering amplitude, which is independent initial conditions. It important stress significantly change shape function as compared fixed case, in particular, leading considerable increase anomalous dimension slow-down rapidity. then concentrate on elucidating differences between two recent calculations corrections. explain difference due an extra contribution kernel, referred subtraction term, arises when are included. These terms were neglected both calculations. evaluate numerically subtractionmore » calculations, demonstrate added back kernels obtained works resulting dipole amplitudes agree each other. use complete kernel including term find full Again regime recovered at very large rapidity unaltered term.« less
