Selection and reconstruction of the top quarks in the all-hadronic decays at a Linear Collider
S. V. Chekanov, V. L. Morgunov
Abstract
A method of reconstruction of the top quarks produced in the process E+E- -> tt -> 6 jets at a Linear Collider (LC) is proposed. The approach does not involve a kinematic fit, as well as assumptions on the invariant masses of the dijets originating from the decays of W bosons and, therefore, the method is expected to be less sensitive to theoretical and experimental uncertainties on the top-mass measurement than traditional reconstruction methods. For the first time, the reconstruction of the top quarks was investigated using the full LC detector simulation after taking into account the background arising from QCD multi-jet production.
