Measuring Higgs boson couplings at the LHC

For an intermediate mass Higgs boson with SM-like couplings the LHC allowsobservation of a variety of decay channels in production by gluon fusion andweak boson fusion. Cross section ratios provide measurements of various ratiosof Higgs couplings, with accuracies of order 15 0.000000or 100 fb^{-1} of data ineach of the two LHC experiments. For Higgs masses above 120 GeV, minimalassumptions on the Higgs sector allow for an indirect measurement of the totalHiggs boson width with an accuracy of 10 to 20, and of the H-->WW partialwidth with an accuracy of about 10
