HERWIRI2: Exponentiated Electroweak Corrections in a Hadronic Event Generator

Understand

Reaching the desired precision level for W and Z processes at the LHC will require a mixture of higher-order QCD and electroweak corrections.

• HERWIRI2 is a step in implementing QED x QCD exponentiation in a hadronic event generator.
• This program implements leading electroweak corrections and coherent exclusive exponentiation in a HERWIG environment.
• We discuss the status of the program, recent tests, and future developments.
