Measurement of Higgs Properties at the LHC
A SM-like Higgs boson can be produced in a variety of channels at the LHC. By
combining information from production via gluon fusion and weak boson fusion,
various partial widths and the total Higgs boson width can be extracted.
Expected accuracies for 200 fb^{-1} of data are in the 10% range.Comment: 6 pages, Revtex (singlespaced), uses epsfig.sty, 1 postscript figure.

Searching for H -> gamma gamma in weak boson fusion at the LHC
Weak boson fusion is a copious source of intermediate mass Higgs bosons at
the LHC, with a rate sigma*B(H -> gamma gamma) of up to 9 fb. The additional
very energetic forward jets in these events provide for a unique signature. A
parton level analysis of the dominant backgrounds demonstrates that this
channel allows the observation of H -> gamma gamma in a low background
environment, with modest luminosity.Comment: 12 pages, 4 figures, submitted to Journal of High Energy Physic
QCD corrections to hadronic WWZ production with leptonic decays
Multi-lepton signatures appear in many new physics searches at the Large
Hadron Collider. We here consider WWZ production with subsequent leptonic decay
of the three vector bosons as a SM source of multi-lepton events. We have
calculated the next-to-leading order QCD corrections for the full
lepton production cross sections in hadronic collisions. Results have been
implemented in the form of a flexible parton-level Monte-Carlo program which
allows to calculate the QCD corrections for arbitrary distributions and
acceptance cuts.Comment: 11 pages, 4 figures, version published in physics letters
