Search for new physics using effective field theory in 13 TeV pp collision events that contain a top quark pair and a boosted Z or Higgs boson

CMS Collaboration

A data sample containing top quark pairs ($\mathrm{t}\bar{\mathrm{t}}$) produced in association with a Lorentz-boosted Z or Higgs boson is used to search for signs of new physics using effe…
