Constraints on the Wtb vertex from early LHC data Aguilar Saavedra, Juan Antonio Castro, N. F. Onofre, Antonio Top quark LHC (Large Hadron Collider) We use the recent measurements of top quark decay asymmetries in ATLAS and the t-channel single top cross section in CMS to set the first combined LHC limits on the Wtb vertex. This combination allows to obtain much better limits than the separate measurements. The resulting constraints are comparable, although still weaker, than the ones obtained using Tevatron data with much more statistics. 2014-02-25T11:52:07Z 2014-02-25T11:52:07Z 2011 info:eu-repo/semantics/article Aguilar-Saavedra, J.A.; Castro, N.F.; Onofre, A.
