Monte Carlo program KORALW 1.02 for W-pair production at LEP2NLC energies with Yennie-Frautschi-Suura exponentiation Original Research Article

The Monte Carlo program KORALW version 1.02 for W-pair production is presented. Its main features are: multiple initial state photonic radiation with finite transverse photon momenta generated according to the Yennie-Frautschi-Suura Monte Carlo technique and massive kinematics for all final particles. Matrix element features second-order leading-logarithmic initial-state QED corrections. The dedicated semi-analytical program KORWAN, with structure-function based leading-logarithmic initial-state photonic radiation up to third order, is also included in the distribution package.
