Comparison of ​HORACE and ​PHOTOS Algorithms for Multiphoton Emission in the Context of Boson Mass Measurement

Table 2

Difference between HORACE and PHOTOS pseudodata in fitted masses. Templates were made using HORACE. The shift in the dimensionless value has been multiplied by 80 GeV to convert to the equivalent shift in the fitted boson mass. The statistical errors are shown. The templates and pseudodata use 10 billion events at the generator level as the input to the detector simulation.
