DOI: 10.1007/jhep04(2019)127
Abstract: A bstractThe production of a Higgs boson in association with at least two jets receives contributions both from the fusion of weak vector bosons (VBF) and from QCD processes, especially gluon fusion (GF). The former… read more here.

DOI: 10.1007/jhep04(2021)196
Abstract: We follow up on our discussion of the exact quark-mass dependence of the Higgs-gluon form factor at three loops in QCD [1] and turn our attention to the closely related Higgs-photon form factor. Similarly to… read more here.

DOI: 10.1103/physrevd.100.114013
Abstract: We consider top-quark mass effects in the Higgs-interference contribution to $Z$-boson pair production in gluon fusion. While this production mechanism is formally of next-to-next-to leading order, its contribution is numerically important above the top threshold… read more here.

DOI: 10.3938/jkps.77.10
Abstract: We determined the quark mass matrix in terms of a small expansion parameter $$\sqrt \varepsilon $$ ε , which gives correctly all the quark masses and the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements on the electroweak (EW)… read more here.
