Abstract
We present a computation of next-to-next-to-leading-order (NNLO) QCD corrections to the production of a Higgs boson in association with a boson at the LHC followed by the decay of the Higgs boson to a pair. At variance with previous NNLO QCD studies of the same process, we treat quarks as massive. An important advantage of working with massive quarks is that it makes the use of flavor jet algorithms unnecessary and allows us to employ conventional jet algorithms to define jets. We compare NNLO QCD descriptions of the associated production with massive and massless quarks and also contrast them with the results provided by parton showers. We find differences in fiducial cross sections computed with massless and massive quarks. We also observe that much larger differences between massless and massive results, as well as between fixed-order and parton-shower results, can arise in selected kinematic distributions.
