Higgs-Strahlung: A Gate to New Physics

Associated VH production, or Higgs-Strahlung for short, is one of the main production modes for Higgs bosons at the LHC. Even though the cross section is very small, the process is of great phenomenological and experimental relevance. This results from the fact that the additional electroweak gauge boson allows for a good background separation. Another great feature of this process is that at NNLO the gg->ZH production channel starts to contribute, which is forbidden for WH production due to charge conservation. This new production mode is very sensitive to New Physics scenarios, but since it is suppressed by a power of alpha_s2 w.r.t. the qqbar induced Higgs-Strahlung it is a big challenge to make this potential BSM effects experimentally accessible. In this talk I will show you why Higgs-Strahlung is still a great tool in the search for New Physics and why the application of a subtraction scheme is essential to construct new sensitive observables.
