Full simulation study of the top Yukawa coupling at the ILC at $\sqrt{s}$ = 1 TeV

We present a study of the expected precision for measurement of the top Yukawa coupling, yt, in e+e- collisions at a center-of-mass energy of 1 TeV and assuming a beam polarization of P (e-, e+) = (-0.8,+0.2). Independent analyses of ttH final states containing at least six hadronic jets are perform...

description We present a study of the expected precision for measurement of the top Yukawa coupling, yt, in e+e- collisions at a center-of-mass energy of 1 TeV and assuming a beam polarization of P (e-, e+) = (-0.8,+0.2). Independent analyses of ttH final states containing at least six hadronic jets are performed, based on detailed simulations of SiD and ILD, the two candidate detector concepts for the ILC. We estimate that a statistical precision of yt of 4% can be obtained with an integrated luminosity of 1 $\mathrm{ab}^{-1}$.

Independent analyses of $\mathrm{t}\bar{\mathrm{t}}\mathrm{H}$ final states containing at least six hadronic jets are performed, based on detailed simulations of SiD and ILD, the two candidate detector concepts for the ILC. We estimate that a statistical precision on $y_{\mathrm {t}}$ of 4.5 % can be obtained with an integrated luminosity of 1 $\mathrm {ab}^{-1} $ that is split equally between two configurations for the beam polarization $P({{\mathrm{e}}}^{-},{{\mathrm{e}}}^{+})$ , $(-80~\%,+20~\%)$ and $(+80~\%,-20~\%)$ . This estimate improves to $4~\%$ if the 1 $\mathrm {ab}^{-1} $ sample is assumed to be fully in the $P({{\mathrm{e}}}^{-},{{\mathrm{e}}}^{+}) = (-80~\%,+20~\%)$ configuration.We present a study of the expected precision for measurement of the top Yukawa coupling, yt, in e+e- collisions at a center-of-mass energy of 1 TeV and assuming a beam polarization of P (e-, e+) = (-0.8,+0.2).
