Description
With focus on the recent ATLAS search for top associated Higgs production in multi-lepton final states, an anomalous rate for the ttW background is unearthed and quantified in terms of theory uncertainties. This anomalous rate is explored in the context of the previously published multi-lepton anomalies at the LHC (JHEP 1910 (2019) 157), using a simplified new physics model. The impact of the model in ttZ measurements is also determined and is shown to be consistent with a mild enhancement of events with low Z transverse momentum. Interesting variables are considered for suggested for future experimental searches to constrain the anomalous ttW rate.
