Higgs couplings at the LHC
The observation of a SM-like Higgs boson in multiple channels at the LHC
allows the extraction of Higgs couplings to gauge bosons and fermions. The
precision achievable at the LHC, for an integrated luminosity of 200 fb^{-1},
is reviewed and updated.Comment: Contributed to APS / DPF / DPB Summer Study on the Future of Particle

Contact Interactions and high Events at HERA
Effective contact interactions can enhance event rates in
scattering at HERA at high . Present constraints from atomic parity
violation measurements and from Drell Yan events at the Tevatron are discussed.Comment: 3 pages, Latex, Talk given at 5th International Workshop on Deep

QCD Corrections to Jet Correlations in Weak Boson Fusion
Higgs boson production via weak boson fusion is sensitive to the tensor
structure of the HVV (V=W,Z) couplings, which distinguishes loop induced
vertices from SM expectations. At the CERN Large Hadron Collider this
information shows up most clearly in the azimuthal angle correlations of the
two forward and backward quark jets which are typical for weak boson fusion. We
calculate the next-to-leading order QCD corrections to this process, in the
presence of anomalous HVV couplings. Gluon emission does not significantly
change the azimuthal jet correlations.Comment: 11 pages, 4 figure
