Resumen:
We analyzed the double production and the triple self-coupling of the standard model Higgsboson at future collider energies, with the reactions ! t¯tHH. We evaluated the totalcross section for t¯tHH and calculated the total number of events considering the complete setof Feynman diagrams at tree-level and for different values of the triple coupling HHH. Thenumerical computation was done for the energy which is expected to be available at a possibleFuture Linear Collider with a center-of-mass energy 5003000 GeV and luminosities of 1000and 5000 fb1. We found that the number of events for the process ! t¯tHH, taking intoaccount the decay products of both t and H, is enough to obtain relevant information aboutthe triple Higgs boson self-coupling.
