Description
Aiming at better understanding of the properties of top quarks, we focus on top--antitop+X production at the LHC, with X being a vector, or scalar/pseudoscalar boson. We show predictions obtained by PowHel, a
computing framework based upon the POWHEG-BOX program with input
obtained from HELAC-NLO. The POWHEG-BOX generates event files
according to the Les-Houches accord, and uses the POWHEG matching
formalism to further evolve these events to the hadron level ready for
use in any experimental analysis. We discuss the sensitivities of our
predictions to the choice of the Shower Monte Carlo code (PYTHIA vs.
HERWIG). We show examples of how the choice of different experimental
cuts and/or heavy particle reconstruction strategies can affect the
predictions and help disentangle our signals from important
backgrounds, also involving top-quark production and decay.
