DESCRIPTION:Higgs production via gauge boson fusion\, due to its unique si
 gnature formed by two tagging jets in the forward and backward region of t
 he detector\, is one of the most important channels for discovery of the H
 iggs boson at the LHC and for exploring its properties. As most of the irr
 educible background originates from other gauge boson fusion processes sha
 ring the same kinematical characteristics\, it is desirable to analyze and
  understand these processes with accuracy that goes beyond the leading ord
 er. I present a method for calculating the next-to-leading-order QCD corre
 ctions to both resonant and non-resonant contributions to the vector boson
  fusion processes\, implementing the Weyl van der Waerden helicity formali
 sm and polarization sums to divide complex Feynman diagrams into blocks an
 d present results for a class of processes associated with production of t
 wo W+. In comparison to the leading order\, the results of this calculatio
 n show a significant reduction in the estimated uncertainties caused by hi
 gher perturbative orders.\n\nhttps://indico.ific.uv.es/event/1866/
