New physics in LHC Higgs boson pair production.

Dolan, Matthew J. and Englert, Christoph and Spannowsky, Michael (2013) 'New physics in LHC Higgs boson pair production.', Physical review D., 87 (5). 055002.


Multi-Higgs production provides a phenomenologically clear window to the electroweak symmetry-breaking sector. We perform a comprehensive and comparative analysis of new electroweak physics effects in di-Higgs and di−Higgs+jet production. In particular, we discuss resonant di-Higgs phenomenology, which arises in the Higgs portal model and in the minimal supersymmetric Standard Model at small tanβ, and nonresonant new-physics contributions to di-Higgs production in models where the newly discovered Higgs candidate is interpreted as a pseudo-Nambu-Goldstone boson. We show that, for all these scenarios, a measurement of the di-Higgs and di−Higgs+jet final states provides an accessible and elaborate handle to understand electroweak symmetry breaking in great detail.
