| Abstract | The contribution of additional samples to the background expectation in a direct measurement of the top Yukawa coupling is investigated. In a previous study, the physics potential of a direct measurement of the top Yukawa coupling was investigated, using the process e+e- --> ttbarH at a sqrt(s) = 1.4 TeV Compact Linear Collider (CLIC) and reconstructed using the CLIC_SiD detector. The expected precision on the top Yukawa coupling was determined to be 4.27%, without beam polarisation. The inclusion of additional non-ttbar(+X) backgrounds has slightly increased the background expectation and an updated precision on the top Yukuwa coupling is determined to be 4.43% with no further optimisation of the selection. |
