Physics potential of the top Yukawa coupling measurement at a 1.4 TeV Compact Linear Collider using the CLIC SiD detector

The physics potential of a direct measurement of the top Yukawa coupling is inves- tigated, using the process e+e− → ttH produced at a √s = 1.4 TeV Compact Linear Collider (CLIC). Final states with six and eight jets are reconstructed. This study addresses various aspects of the detector performance...

description The physics potential of a direct measurement of the top Yukawa coupling is inves- tigated, using the process e+e− → ttH produced at a √s = 1.4 TeV Compact Linear Collider (CLIC). Final states with six and eight jets are reconstructed. This study addresses various aspects of the detector performance: jet clustering in complex hadronic final states, missing energy reconstruction, flavour-tagging and the iden- tification of high-energy leptons. The analysis is based on full CLIC SiD detector simulation using GEANT4. Beam-induced backgrounds from γγ → hadrons inter- actions are overlaid on top of the physics events. The expected precision on the top Yukawa coupling is determined to be 4.27%, without beam polarisation.
