Phenomenology of t(t)over-barj plus X production at the LHC

We present phenomenological results for t (t) over barj + X production at the Large Hadron Collider, of interest for designing forthcoming experimental analyses of this process. We focus on those cases where the t (t) over barj + X process is considered as a signal. We discuss present theoretical uncertainties and the dependence on relevant input parameters entering the computation. For the R. distribution, which depends on the invariant mass of the t (t) over barj-system, we present reference predictions in the on-shell, (MS) over bar and MSR top-quark mass renormalization schemes, applying the latter scheme to this process for the first time. Our conclusions are particularly interesting for those analyses aiming at extracting the topquark mass from cross-section measurements.

Automated summary

We present phenomenological results for t(t) over barj + X production at the Large Hadron Collider, focusing on the cases where this process is considered as a signal. We discuss theoretical uncertainties and the dependence on input parameters in the computation. Reference predictions for the R. distribution are provided in three different mass renormalization schemes, with the MSR scheme applied for the first time. Our conclusions are particularly relevant for analyses aiming at extracting the top-quark mass from cross-section measurements.
