Limits on anomalous top quark gauge couplings from Tevatron and LHC data
(2015-01-01)
We review and update current limits on possible anomalous couplings of the top quark to W gauge bosons. We consider data from top quark decay (as encoded in the W-boson helicity fractions) and single-top production (in the ...
Stringent limits on top-quark compositeness from t t ̄ production at the Tevatron and the lhc stringent limits on top-quark compositeness ⋯ M. fabbrichesi, M. pinamonti, and A. tonero
(2014-04-11)
If the top quark is a composite state made out of some constituents, then its interaction with the gluon will be modified. We introduce the leading effective operators that contribute to the radius and anomalous magnetic ...
