These differential cross-sections are presented in a data set corresponding to an integrated luminosity of 4.6 fb$^{−1}$. The differential cross-sections are presented in terms of kinematic variables, such as momentum, rapidity and invariant mass, of a top-quark proxy referred to as the pseudo-top-quark as well as the pseudo-top-quark pair system. The dependence of the measurement on theoretical models is minimal.engjournal article2019-02-04
