“…The measurement of the triple Higgs coupling using non-resonant dihiggs production at both the LHC and future 100 TeV collider has been studied in great detail in the literature which was recently reviewed in [22]. Among all the channels for the Higgs decay final state, the bbγγ channel [71][72][73][74][75][76][77][78] is the most promising due to the combination of large h → bb branching ratio and more accurate reconstruction of photon momentum compared with other channels which helps reduce the backgrounds.…”

“…Due to destructive interference between these two contributions, the dihiggs production cross section in the SM is typically small and thus challenging to observe in the near future. However, in the scalar extended models, the dihiggs cross section may be increased considerably making measurement a possibility at the proposed 100 TeV collider [21,22]. In this paper we investigate the dihiggs production cross sections in the EFT framework, and study the discovery potential of the Wilson coefficients in the EFT at the proposed 100 TeV collider.…”

We consider extended scalar sectors of the Standard Model as ultraviolet-complete motivations for studying the effective Higgs self-interaction operators of the Standard Model effective field theory. We investigate all motivated heavy scalar models which generate the dimension-6 effective operator, |H| 6 , at tree level and proceed to identify the full set of tree-level dimension-six operators by integrating out the heavy scalars. Of seven models which generate |H| 6 at tree level only two, quadruplets of hypercharge Y = 3YH and Y = YH , generate only this operator. Next we perform global fits to constrain relevant Wilson coefficients from the LHC single Higgs measurements as well as the electroweak oblique parameters S and T . We find that the T parameter puts very strong constraints on the Wilson coefficient of the |H| 6 operator in the triplet and quadruplet models, while the singlet and doublet models could still have Higgs self-couplings which deviate significantly from the standard model prediction. To determine the extent to which the |H| 6 operator could be constrained, we study the dihiggs signatures at the future 100 TeV collider and explore future sensitivity of this operator. Projected onto the Higgs potential parameters of the extended scalar sectors, with 3 ab −1 luminosity data we will be able to explore the Higgs potential parameters in all seven models. arXiv:1705.02551v2 [hep-ph] 22 Nov 2017 2 An exception to this is the HS 3 or HS 2 vertex, however the HS 3 vertex will not generate operators at tree level below dimension-eight and the HS 2 vertex does not exist for any representations given the Higgs is a doublet of SU (2) L .

“…Other production processes may also be interesting for our aim. One set is ZW W production from different initial states like γ − γ, see [16], or gluon-gluon in hadronic collisions; for LHC possibilities see [17,18]. Another possibility is HW W or HZZ production which will also directly depend on Z, W masses but the identification of the H may be more delicate than for a Z. e…”

We show that the ZW W production process may give complementary informations about scale dependent heavy particle masses and possible final state interactions as compared to previously studied top quark production processes. We illustrate the p Z distribution of the rate of longitudinal Z L component showing its sensitivity to these effects which may arise from heavy particle substructure or a dark matter (DM) environment.

“…For the b bb b production, the observed upper limit by ATLAS using the non-resonant Higgs pair production data is 13 times the SM value at 95% C.L [11]. There are also extensive phenomenological studies on determinning the trilinear Higgs self-coupling directly at the LHC [12][13][14][15][16][17][18][19][20][21], the future electron-positron collider [22][23][24][25], and future high energy hadron colliders [26][27][28][29][30][31][32][33][34], in which strict constraints are obtained with higher integrated luminosities and energies. On the other hand, an indirect method is proposed for constraining the Higgs self-coupling via single Higgs production at next-to-leading order (NLO) [24,[35][36][37][38][39].…”

Probing the trilinear Higgs boson self-coupling via single Higgs production at the LHeC

The determination of the Higgs self coupling is one of the key ingredients for understanding the mechanism behind the electroweak symmetry breaking. An indirect method for constraining the Higgs trilinear self coupling via single Higgs production at next-to-leading order (NLO) has been proposed in order to avoid the drawbacks of studies with double Higgs production. In this paper we study the Higgs self interaction through the vector boson fusion (VBF) process e − p → ν e hj at the future LHeC. At NLO level, we compute analytically the scattering amplitudes for relevant processes, in particular those induced by the Higgs self interaction. A Monte Carlo simulation and a statistical analysis utilizing the analytic results are then carried out for Higgs production through VBF and decay to bb, which yield for the trilinear Higgs self-coupling rescaling parameter κ λ the limit [-0.28, 4.25] with 2 ab −1 integrated luminosity. If we assume 10% of the signal survives the event selection cuts, and include all the background, the constraint will be broadened to [-1.95, 5.93].
