The Triple Higgs Boson Self-Coupling at Future Linear e+e- Colliders Energies: ILC and CLIC

Abstract

We analyzed the triple Higgs boson self-coupling at future $e^{+}{e}^{-}$ colliders energies, with the reactions $e^{+}{e}^{-}\to b\bar{b}HH,t\bar{t}HH$. We evaluate the total cross-sections for both $b\bar{b}HH$ and $t\bar{t}HH$, and calculate the total number of events considering the complete set of Feynman diagrams at tree-level. We vary the triple coupling $\kappa {\lambda }_{3H}$ within the range $\kappa =-1$ and +2. The numerical computation is done for the energies expected to be available at a possible Future Linear $e^{+}{e}^{-}$ Collider with a center-of-mass energy $800,1000,1500$ $GeV$ and a luminosity 1000 $f{b}^{-1}$. Our analysis is also extended to a center-of-mass energy 3 $TeV$ and luminosities of 1000 $f{b}^{-1}$ and 5000 $f{b}^{-1}$. We found that for the process $e^{+}{e}^{-}\to b\bar{b}HH$, the complete calculation differs only by 3% from the approximate calculation $e^{+}{e}^{-}\to ZHH(Z\to b\bar{b})$, while for the process $e^{+}{e}^{-}\to t\bar{t}HH$, the expected number of events, considering the decay products of both $t$ and $H$, is not enough to obtain an accurate determination of the triple Higgs boson self-coupling.
