v2 v3 7 7 * A light SM Higgs boson mostly decays into $b\bar b$. Compute the decay rate for $H\rightarrow b\bar b$. 8 8 * For a Higgs mass of around 160 !GeV, the main decay mode is $H\rightarrow WW$. Compute the decay rate. 9 The Higgs branching ratios can be found [ http://cp3wks05.fynu.ucl.ac.be/twiki/pub/Physics/DiscoverTheHiggs/h-br.pdf here].9 The Higgs branching ratios can be found [attachment:h-br.pdf here]. 10 10 11 11 You may also have a look at the following Mathematica [http://cp3wks05.fynu.ucl.ac.be/twiki/bin/viewfile/Physics/HiggsPheno?rev=1;filename=HDecay.nb notebook]. … … 21 21 For details on the calculation of the top loop and the effective theory, see the notes and/or check the following Mathematica notebooks (which actually contain much more information): 22 22 23 1. pp>H at LO (1-loop): details of the calculation (Mathematica Notebook) [ http://cp3wks05.fynu.ucl.ac.be/twiki/pub/Physics/GIFSchool/HiggsGG-LO-mtfinite.nb HiggsGG-LO-mtfinite.nb]24 1. pp>H at NLO: details of the calculation (Mathematica Notebook) [ http://cp3wks05.fynu.ucl.ac.be/twiki/pub/Physics/GIFSchool/HiggsGG-NLO.nb higgsGG-NLO.nb]25 1. pp>H at NLO: cross section evaluation for the LHC (Mathematica Notebook+PDF libraries to be compiled) [ http://cp3wks05.fynu.ucl.ac.be/twiki/pub/Physics/GIFSchool/phenHiggs.tar.gz phenHiggs.tar.gz].23 1. pp>H at LO (1-loop): details of the calculation (Mathematica Notebook) [attachment:HiggsGG-LO-mtfinite.nb HiggsGG-LO-mtfinite.nb] 24 1. pp>H at NLO: details of the calculation (Mathematica Notebook) [attachment:HiggsGG-NLO.nb higgsGG-NLO.nb] 25 1. pp>H at NLO: cross section evaluation for the LHC (Mathematica Notebook+PDF libraries to be compiled) [attachment:phenHiggs.tar.gz phenHiggs.tar.gz]. 26 26 27 27 Exercise (DIFFICULT but interesting!!): Use the all the material above to derive the EFT description of a pseudo-scalar Higgs, A, … … 43 43 1.
