Title: Full simulation study of the top Yukawa coupling at the ILC at √s = 1 TeV

Abstract

We present a study of the expected precision for the measurement of the top Yukawa coupling, y_t, in e⁺e^- collisions at a center-of-mass energy of 1 TeV. Independent analyses of tt-barH 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_t of 4.5 % can be obtained with an integrated luminosity of 1 ab^-1 that is split equally between two configurations for the beam polarization P(e^-,e⁺), (-80 %,+20 %) and (+80 %,-20 %). This estimate improves to 4 % if the 1 ab^-1 sample is assumed to be fully in the P(e^-,e⁺)=(-80 %,+20 %) configuration.

A search is performed for Higgs bosons produced in association with top quarks using the diphoton decay mode of the Higgs boson.

The dataset used corresponds to an integrated luminosity of 4.5 fb^-1 of proton–proton collisions at a center-of-mass energy of 7 TeV and 20.3 fb^-1 at 8 TeV recorded by the ATLAS detector at the CERN Large Hadron Collider.

Results are presented for an extraction of the top quark Yukawa coupling from top quark-antiquark (tt) kinematic distributions in the lepton plus jets final state in proton-proton collisions, based on data collected by the CMS experiment at the LHC at s=13 TeV, corresponding to an integrated luminosity of 35.8 fb-1. Corrections from weak boson exchange, including Higgs bosons, between the top quarks can produce large distortions of differential distributions near the energy threshold of tt production. Therefore, precise measurements of these distributions are sensitive to the Yukawa coupling. Top quark events are reconstructed with at least three jets in themore »« less

Towards a precise measurement of the top quark Yukawa coupling at the ILC

Conference Juste, A. - ECONF C0508141:ALCPG0426,2005

A precise measurement of the top quark Yukawa coupling is of great importance, since it may shed light on the mechanism of EWSB. We study the prospects of such measurement during the first phase of the ILC at {radical}s = 500 GeV, focusing in particular on recent theoretical developments as well as the potential benefits of beam polarization. It is shown that both yield improvements that could possibly lead to a measurement competitive with the LHC.
