Resumen:
We investigate a charge asymmetry in tt¯γ production at the LHC that provides complementary information to the measured asymmetries in tt¯ production. We estimate the experimental uncertainty in its measurement at the LHC with 8 and 14 TeV. For new physics models that simultaneously reproduce the asymmetry excess in tt¯ at the Tevatron and the SM-like asymmetry at the LHC, the measurement in tt¯γ at the LHC could exhibit significant deviations with respect to the SM prediction.
