Summary: | Phys. Rev. D 93, 113021 (2016) The latest and most precise top quark measurements at the LHC and Tevatron
are used to establish new limits on the $Wtb$ vertex. Recent results on the
measurements of the $W$-boson helicity fractions and single top quark
production cross section are combined in order to establish new limits at 95%
CL (confidence level). The allowed regions for these limits are presented, for
the first time, in three-dimensional graphics, for both real and imaginary
components of the different anomalous couplings, providing a new perspective on
the impact of the combination of different physics observables. These results
are also combined with the prospected future measurement of the single top
quark production cross section and $W$-boson helicity fractions at the LHC. |
