软胶子抵消、相位和初态部分子因式分解

Soft-Gluon Cancellation, Phases and Factorization with Initial-State Partons

S. Mert Aybat, George Sterman

摘要:

我们概述的参数取消软奇异的过渡概率和部分子分布与传入的部分子和威尔逊线,并与观察到的喷气机或重有色粒子在最终状态。我们展示了Glauber胶子和发散相的消除,将有限的修正与因式分解截面中对最终态的限制相关联。

英文摘要:

We outline arguments for the cancellation of soft singularities in transition probabilities and parton distributions with incoming partons and Wilson lines, and with observed jets or heavy colored particles in the final states. We show the cancellation of Glauber gluons and divergent phases, relating finite remainders to corrections that arise from restrictions on final states in factorized cross sections.
