Description
The process ee->qq with qq=ss,cc,bb,tt plays a central role in the physics programs of high energy electron-positron colliders operating from the O(100GeV) to O(1TeV) center of mass energies. Furthermore, polarised beams as available at the International Linear Collider (ILC) are an essential input for the complete measurement of the helicity amplitudes that govern the production cross section. Quarks, specially the heaviers, are likely messengers to new physics and at the same time they are ideal benchmark processes for detector optimisation. All four processes call for superb primary and secondary vertex measurements, a high tracking efficiency to correctly measure the vertex charge and excellent hadron identification capabilities. Strange, charm and bottom production are already available below the ttbar threshold.
This contribution will cover the most relevant and latest activities of the ILD concept group on physics studies related to heavy quarks, using detailed simulation and realistic analysis tools
to determine the full potential of ILC on this area. Some of the topics to be discussed will be the top-quark mass measurements, top and less heavy quarks electroweak couplings or BSM searches at ILC with the ILD.
