Laguerre method to solve parton evolution equations

- Summary
- Metrics

Abstract

The DGLAP evolution equations for non‐singlet sector of parton density is solved in x‐space based on Laguerre polynomial expansion. High numerical accuracy is achieved by expanding over a set of approximately 30 polynomials. The result of evolved parton densities to high energy scales are in good agreement with phenomenological GRV model. To improve the results we can employ a constituent quark model.
