A Consistent Prescription for Combining Perturbative Calculations and Parton Showers in Case of Associated Z b anti-b Hadroproduction

TL;DR

This paper introduces a Monte Carlo method that consistently combines perturbative matrix element calculations with parton shower algorithms for Z boson production with bottom quarks, including heavy quark masses and overlap removal.

Contribution

It provides a novel Monte Carlo algorithm that integrates perturbative calculations and parton showers for Z + b anti-b production, accounting for heavy quark effects.

Findings

Successful implementation of the combined method

Improved accuracy in modeling Z + b anti-b processes

Inclusion of heavy quark masses enhances realism

Abstract

This paper presents the method of combining parton shower formalism with perturbative calculations (matrix elements) in form of a Monte-Carlo algorithm for the process g g -> Z b anti-b,consistenlty including the heavy quark masses and overlap removal.
