Small-x F_2 Structure Function of a Nucleus Including Multiple Pomeron Exchanges
Yuri V. Kovchegov (University of Minnesota)
TL;DR
This paper derives an evolution equation for the small-x F_2 structure function of a nucleus, incorporating multiple pomeron exchanges within Mueller's dipole model, and connects it to the GLR equation in a specific limit.
Contribution
It introduces a comprehensive evolution equation for nuclear structure functions that accounts for multiple pomeron exchanges, extending previous models.
Findings
The derived equation includes all multiple pomeron exchanges in the leading logarithmic approximation.
In the double leading logarithmic limit, the equation simplifies to the well-known GLR equation.
The approach provides a unified framework for small-x nuclear structure function evolution.
Abstract
We derive an equation determining the small-x evolution of the F_2 structure function of a large nucleus which includes all multiple pomeron exchanges in the leading logarithmic approximation using Mueller's dipole model. We show that in the double leading logarithmic limit this evolution equation reduces to the GLR equation.
