Gluon density and F2 functions from BK equation with impact parameter dependence in DIS on nuclei
The DIS process on nuclei is considered in the framework of LO BK equation with local impact parameter dependence. Solving BK equation parameters for initial conditions of GBW type found in [4] were used. Integrated gluon density function and F2 nucleus structure function for different nuclei are calculated. Obtained results are compared with the different parameterizations of integrated gluon ...
متن کاملGluon density and F2 functions from BK equation with impact parameter dependence
The LO BK equation for unintegrated gluon density with impact parameter dependence is considered. The form of initial condition for the equation is determined, which is similar to the form of fenomenological GBW ansatz. The gluon density function and F2 function are calculated and compared with the results for the gluon density and F2 functions from the GRV parameterization for different values...
متن کاملImpact Parameter Dependence in the Balitsky-Kovchegov Equation
We study the impact parameter dependence of solutions to the Balitsky-Kovchegov (BK) equation. We argue that if the kernel of the BK integral equation is regulated to cutoff infrared singularities, then it can be approximated by an equation without diffusion in impact parameter. For some purposes, when momentum scales large compared to ΛQCD are probed, the kernel may be approximated as massless...

متن کاملParameter Dependence in Cumulative Selection
Cumulative selection is a powerful process in which small changes accumulate over time because of their selective advantage. It is central to a gradualist approach to evolution, the validity of which has been called into question by proponents of alternative approaches to evolution. An important question in this context concerns how the efficiency of cumulative selection depends on various para...
