2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/49483A feasibility study of the measurement of the top-Higgs Yukawa coupling at a future linear e+e- collider operating at sqrt(s)=800 GeV is presented. As compared to previous existing studies, much effort has been put in a ``realistic simulation'' by including irreducible+reducible backgrounds, realistic detector effects and reconstruction procedures and finally, a multivariate analysis. Both hadronic and semileptonic decay channels have been considered.LaTex, 27 pages, 14 Postscript figuresHigh Energy Physics - Phenomenologytext
