SUMMARY:Top quark effective theory in the LHC era - Michael Russell (Glasg
 ow)
DTSTART:20161004T140000Z

UID:TALK64614@talks.cam.ac.uk
CONTACT:Alexander Mitov
DESCRIPTION:The top quark\, by far the heaviest of the Standard Model ferm
 ions\, is ubiquitous in Large Hadron Collider measurements\, both as a dom
 inant background and as a potential gateway to signals of new physics. The
  huge statistical sample already collected at the LHC will allow us\, for 
 the first time\, to study its couplings with precision. In this talk\, I w
 ill discuss a global fit of top quark couplings\, phrased in the model-ind
 ependent language of higher-dimensional effective operators\, to the curre
 ntly available data from the LHC and Tevatron. I examine the interplay bet
 ween inclusive and differential measurements\, and the complementarity of 
 LHC and Tevatron results\, as well as issues pertaining to the validity of
  the EFT description. I will conclude with a discussion of projections for
  improvement over LHC Run II\, and of the implications of our results for 
 the scale of new physics in the top sector.
