DESCRIPTION:Speakers: Chung Kao (University of Oklahoma)\nThe results from
  the LHC indicate that the couplings of the Higgs boson to other particles
  are consistent with the Standard Model. However the final and ultimate te
 st as to whether this particle \nis the standard Higgs boson will be the c
 oupling of the Higgs boson to itself. We study the Higgs pair production f
 rom gluon fusion at the LHC and try to determine how accurately the trilin
 ear Higgs coupling can be determined theoretically.\nLet us introduce a ge
 neral trilinear Higgs coupling as \nkappa x lambda_HHH(SM). For the Standa
 rd Model\, kappa = 1.\nWe found that at the LHC with a center of mass of e
 nergy [sqrt(S)]of 14 TeV\, the measurement of cross section of 40 fb with 
 negligible experimental error would only restrict kappa to be between 0.86
  and 1.12. For sqrt(S) = 100 TeV\, the value of kappa will be limited to b
 e between 0.89 and 1.10 that is slightly better than the lower energy.\n\n
