Soft quark effects on H+jet production at NLP accuracy
arxiv(2024)
摘要
We define soft quark operators that enable construction of colour-ordered
helicity amplitudes out of the non-radiative ones. We explore these operators
for Higgs plus one jet production in a hadron collider and study the
next-to-leading power corrections on all partonic channels involving quark(s)
and/or anti-quark(s). We also investigate the effect of next-to-soft gluon
radiation in these channels employing the technique illustrated in
. Analytical expressions of next-to-leading power leading
logarithms thus obtained are simple and compact in nature. Further, we discuss
the connection of such logarithms with that of the pseudo-scalar Higgs plus one
jet production.
