“…The one-loop radiative corrections to the double Higgs-strahlung process are also very involved to calculate since, already at the tree-level, one has to deal with three massive particle in the final state and, thus, one has to consider pentagonal diagrams and fourbody finals states at NLO. They have again been calculated recently by two independent groups [527,528], with results that agree reasonably, in particular at low energies. The QED corrections follow the same trend as what has been observed in the case of the e + e − → ttH process for M H = 150 GeV: they are very large and negative for c.m.…”

“…The one-loop electroweak and QCD radiative corrections to the most important production mechanisms have been completed only recently [517][518][519][520][521][522][523][524][525][526][527][528][529] and their main effects will be summarized.…”

“…In e + e − collisions, the full O(α) electroweak corrections to both the double Higgs-strahlung process e + e − → ZHH [91,92] and the W W fusion-dominated process e + e − → ν νHH [93] are known. The theoretical uncertainties in these cross sections are well below the anticipated experimental precision.…”

The search for Higgs bosons in both the standard model and its extensions is well under way at the Tevatron. As the integrated luminosity collected increases into the multiple inverse femptobarn range, these searches are becoming very interesting indeed. Meanwhile, the construction of the Large Hadron Collider (LHC) and its associated experiments at CERN are nearing completion. In this TeV4LHC workshop, it was realized that any experience at the Tevatron with respect to backgrounds, experimental techniques and theoretical calculations that can be verified at the Tevatron which have relevance for future measurements at the LHC were important. Studies and contributions to these efforts were made in three broad categories: theoretical calculations of Higgs production and decay mechanisms; theoretical calculations and discussions pertaining to non-standard model Higgs bosons; and experimental reviews, analyses and developments at both the Tevatron and the upcoming LHC experiments. All of these contributions represent real progress towards the elucidation of the mechanism of electroweak symmetry breaking. ¶ Convenors of the Higgs Working Group † Organizers of the TeV4LHC Workshop

“…The one-loop radiative corrections to the process were calculated in refs. [22,23]. The total cross section in the minimal supersymmetric extension of the SM [24][25][26][27][28], that in composite Higgs models [29,30] and that in other several new physics models [31] have also been studied in detail.…”

Consequences of non-standard Higgs couplings in the final-state distributions of the process e + e − → ZHH are studied. We derive an analytic expression for the differential cross section, which has in the most general case 9 non-zero functions. These functions are the coefficients of 9 angular terms, depend on the Higgs couplings, and can be experimentally measured as observables. Symmetry properties of these 9 functions are carefully discussed, and they are divided into 4 categories under CP and CP T. The relations between our observables and the observables which exist in the literature are also clarified. We numerically study the dependence of our observables on the parameters in an effective Lagrangian for the Higgs couplings. It is shown that these new observables depend on most of the effective Lagrangian parameters in different ways from the total cross section. A benefit from longitudinally polarized e + e − beams is also discussed.
