Abstract

We present a method to establish, experimentally, the relation between the top-quark mass m_t^MC as implemented in Monte Carlo generators and the Lagrangian mass parameter m_t in a theoretically well-defined renormalization scheme. We propose a simultaneous fit of m_t^MC and an observable sensitive to m_t, which does not rely on any prior assumptions about the relation between m_t and m_t^MC. The measured observable is independent of m_t^MC and can be used subsequently for a determination of m_t. The analysis strategy is illustrated with examples for the extraction of m_t from inclusive and differential cross sections for hadroproduction of top quarks.
