- MEtop - a generator for single top production via FCNC interactionsPublication . Coimbra, Rita; Onofre, Antonio; Santos, Rui; Won, MiguelWe present a generator for single top quark production via flavour-changing neutral currents. The MEtop event generator allows for Next-to-Leading-Order direct top production $pp \to t$ and Leading-Order production of several other single top processes. A few packages with definite sets of dimension six operators are available. We discuss how to improve the bounds on the effective operators and how well new physics can be probed with each set of independent dimension six operators.
- MEtop – a top FCNC event generatorPublication . Coimbra, Rita; Onofre, António; Santos, Rui; Won, MiguelWe present a new Monte Carlo generator for Direct top and Single top production via flavour-changing neutral currents (FCNC). This new tool calculates the cross section and generates events with Next-to-Leading order precision for the Direct top process and Leading-Order precision for all other FCNC single top processes. A set of independent dimension six FCNC operators has been implemented - including four-fermion operators - where at least one top-quark is present in the interaction.
