The abstract, sentence by sentence

arXiv listing abstract v2. Results and the main claim are underlined; .

Higgs pair production is crucial for measuring the Higgs boson self-coupling. The dominant channel at hadron colliders is gluon fusion via heavy-quark loops. We present the results of a fully exclusive simulation of gluon fusion Higgs pair production based on the matrix elements for hh + 0, 1 partons including full heavy-quark loop dependence, matched to a parton shower. We examine and validate this new description by comparing it with (a) Higgs Effective Theory predictions, (b) exact hh + 0-parton sample showered by pythia, and (c) exact hh+1-parton distributions, by looking at the most relevant kinematic distributions, such as PTh, PThh, Mhh spectra, and jet rate as well. We find that matched samples provide an state-of-the-art accurate exclusive description of the final state. The relevant LHE files for Higgs pair productions at the LHC can be accessed via http://hepfarm02.phy.pku.edu.cn/foswiki/CMS/HH, which can be used for relevant experimental analysis.

  • Measuring Higgs pair productions can be sensitive to $g_HHH$ and thus $λ$ (for recent phenomenology papers, see e.g. [ref] ).

  • In particular, the Higgs self coupling is crucial as it is the only portal to reconstruct and verify the Standard Model (SM) like scalar potential (see e.g. [ref] ): [equation] which leads to the triple- and quartic-Higgs couplings [equation] In the SM, one has $v=√(μ^2/λ)$ being the Higgs field vacuum expectation value, and the higgs mass $m_H=√(2λ)v$.

  • The discovery of a 125-126 GeV Higgs-like boson [ref] , together with the early measurement on its properties [ref] , forsees a new era in particle physics to understand more in detail the mechanism of electroweak symmetry breaking, in which precision measurement on Higgs couplings will play a very important task, in demand of the forthcoming upgraded LHC and the promising circular or linear $e^+e^-$ collider.
