Top Momentum and Extra Soft Jets
Lynne H. Orr, W. J. Stirling
Abstract
Top pairs produced at the Tevatron may be accompanied by extra jets due to radiation of soft gluons. Whether these jets should be included in top momentum reconstruction depends on the source of the gluons, which can be radiated off the initial partons, the final state b quarks, or the intermediate top quarks. We compute soft gluon distributions and discuss their implications for top mass measurements.
