=== Study feasibility of double Higgs production via Vector Boson Fusion at the LHC ===

Interested people: Roberto, Christophe, Matthew, Gustaaf, Filip, Son, Bondu, Massironi, Yun ... (please add your name!)  

Relevant literature: [[http://arxiv.org/abs/arXiv:1206.5001|1206.5001]], [[http://arxiv.org/abs/arXiv:1210.8166|1210.8166]], [[http://arxiv.org/abs/arXiv:1002.1011|1002.1011]]

To do:
      - tabulate figures of merit for signal and most relevant backgrounds in the following channels: bbbb, bbWW, bbtautau.
      - which kind of future collider (ILC, CLIC, 100 TeV pp, ...) would be sensitive?

==== General Topics that were discussed at Les Houches ====

1) check feasability of WW->hh: which channel (WWbb)? which lumi? is energy upgrade competitive?

2) sensitivity on trilinear H^3 in gg->hh vs gg->h (at two loops): by the time we are able to measure it, will gg->hh be competitive with single higgs?

3) check extraction of anomalous couplings (e.g. cH) using double Higgs strahlung at the LHC

4) effect of resonances (ex: heavy scalar decaying to hh) in double-Higgs production
