摘要We make a full tree level study of the signatures of anomalous gauge couplings of the Higgs boson at the CERN LHC via the semileptonic decay mode in WW scatterings, pp -> W(+)W(+/-)j(1)(f)j(2)(f)-> l(+)nu(l)j(1)j(2)j(1)(f)j(2)(f). Both signals and backgrounds are studied at the hadron level for the Higgs mass in the range 115 GeV <= m(H)<= 200 GeV. We carefully impose suitable kinematical cuts for suppressing the backgrounds. To the same sensitivity as in the pure leptonic mode pp -> W(+)W(+)j(1)(f)j(2)(f)-> l(+)nu(l)l(+)nu(l)j(1)(f)j(2)(f), our result shows that the semileptonic mode can reduce the required integrated luminosity by a factor of 3. If the anomalous couplings in nature are actually larger than the sensitivity bounds shown in the text, the experiment can start the test for an integrated luminosity of 50 fb(-1).
