Les Houches Themes



This is an old revision of the document!

Higgs Working Group

Some topics for Session 1

a) PDF uncertainties for gluon-gluon fusion

  • -trace differences between CTEQ, MSTW and NNPDF to see if uncertainty can be reduced

b) Acceptances and uncertainties of acceptances for Higgs (gg→Higgs→WW/ZZ)

c) Higgs+jets cross sections

  • - comparisons of @MC@NLO, Powheg MINLO, MEPS@NLO, HEJ, etc
  • - comparisons of W/Z+jets with above (+LoopSim) as a testbed
  • - revisit tag jets: hadronization uncertainties for high rapidity jets

d) Higgs+jets uncertainties

  • -new scheme for jet veto uncertainties using Higgs+0, Higgs+1 jet resummation calculations
  • -comparison of Higgs+0 jet resummation results

e) Higgs+b's (ex: VH,H→bb)

f) Double Higgs production

g) H → 2gamma (signal and background)


Higgs+dijets (ggF) uncertainty study

Some topics for Session 2

a) [hel | Higgs Effective Lagrangian (HEL)]

  • implementation of HEL in MC generators (ex: gg→h, h→4f)
  • wishlist of NLO calculations within the HEL approach
  • updated and complete analysis of current constraints from Higgs, flavor and precision data on the coefficients of HEL
  • estimate of future sensitivity of the LHC on the coefficients of HEL

b) Identify most promising Higgs observables and processes to discover New Physics, given the current constraints and exclusion limits:

  1. from the viewpoint of specific models. Ex: natural SUSY, composite Higgs
  2. from the viewpoint of the HEL

c) Higgs and Dark Matter: Higgs portal models, Higgs→invisible, Higgs + invisible associated production

d) Higgs in decays of New Heavy particles

e) effects of NP on Higgs BR's, using existing contraints (SUSY was done during last Les Houches)
