We present the analytic computation of the planar master integrals which occurs in the calculation of the two-loop light fermion electroweak corrections to the production of a Higgs boson in association with a jet in gluon-gluon fusion channel. The complete dependence on the electroweak-boson mass has been taken into account. The evaluation of the master integrals is done using the differential equation method with the canonical basis approach. The solution is given as a series expansion in the dimensional regularization parameter up to weight four. The coefficients in the expansion are given in terms of multiple-polylogarithms.

Abstract
We present the analytic computation of the planar master integrals which occurs in the calculation of the two-loop light fermion electroweak corrections to the production of a Higgs boson in association with a jet in gluon-gluon fusion channel. The complete dependence on the electroweak-boson mass has been taken into account. The evaluation of the master integrals is done using the differential equation method with the canonical basis approach. The solution is given as a series expansion in the dimensional regularization parameter up to weight four. The coefficients in the expansion are given in terms of multiple-polylogarithms.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
