Higgs vacua with potential barriers

“…Enhancements of around 100% are typical for low values of m 2 S , making measurements of the Higgs cubic interaction a powerful probe of these scenarios. The deviations with respect to the SM value are larger than the expected precision of 20% achievable at prospective linear colliders [57]; also, cubic couplings enhanced by a factor of 2 could be measurable at the LHC [58,59]. The results obtained here are larger than the corresponding N = 6 values in ref.…”

Investigating perturbative unitarity in the presence of anomalous couplings

“…Vector boson scattering has drawn a lot of attention earlier and many works exist in the literature that discuss the gauge boson scattering and unitarity problems [12]. The anomalous gauge and gauge-Higgs couplings and their limits in various models as well as in modelindependent approach have also been studied in various papers [13][14][15][16][17][18][19][20][21].…”

“…For example, the subprocess gg → HH obviously depends on the three Higgs coupling as does gg → ttHH [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Processes with three Higgs bosons in the final state are necessary to determine κ 4 .…”
