大横动量下电弱玻色子产生的NNLO软函数

NNLO soft function for electroweak boson production at large transverse momentum

Thomas Becher, Guido Bell, Stefanie Marti

摘要:

在次领先阶下计算了强子对撞机产生大横动量电弱玻色子(光子、W、Z或H)的软函数。这是涉及三个光锥方向的软函数的第一个双循环计算。因此,这些过程的阈值重算现在可以以次-领先的对数精度执行。

英文摘要:

The soft function relevant for the production of an electroweak boson (photon, W, Z or H) with large transverse momentum at a hadron collider is computed at next-to-next-to-leading order. This is the first two-loop computation of a soft function involving three light-cone directions. With the result, the threshold resummation for these processes can now be performed at next-to-next-to-next-to-leading logarithmic accuracy.
