### Impact of electroweak corrections on neutral Higgs boson decays in extended Higgs sectors

- PhysicsJournal of High Energy Physics
- 2020

Precision predictions play an important role in the search for indirect New Physics effects in the Higgs sector itself. For the electroweak (EW) corrections of the Higgs bosons in extended Higgs…

### Estimations for the single diffractive production of the Higgs boson at the Tevatron and the LHC

- Physics
- 2011

The single diffractive production of the standard model Higgs boson is computed using the diffractive factorization formalism, taking into account a parametrization for the Pomeron structure function…
