SINGLE TOP PRODUCTION IN THE Wt MODE WITH MC@NLO

نویسنده

  • Chris D. White
چکیده

We consider whether Wt production can be considered as a distinct production process at the LHC, separate from top pair production with which it interferes. We argue that this problem can be meaningfully addressed in an MC@NLO calculation, and give two definitions of the Wt mode whose difference measures the degree of interference between Wt and top pair production. These are then implemented in the MC@NLO software framework, and results given which demonstrate that it is indeed legitimate to isolate the Wt process, subject to adequate cuts.

Single-top hadroproduction in association with a W boson

We present the calculation of the Wt single-top production channel to nextto-leading order in QCD, interfaced with parton showers within the MC@NLO formalism. This channel provides a complementary way of investigating the properties of the Wtb vertex, with respect to the sand t-channels. We pay special attention to the separation of this process from top quark pair production.

Isolating Wt production at the LHC

We address the issue of single top production in association with a W boson at the Large Hadron Collider, in particular how to obtain an accurate description in the face of the top pair production background given that the two processes interfere with each other. We stress the advantages of an MC@NLO description, and find that for cuts used to isolate the signal, it makes sense to consider Wt a...
