Measurement of the $t\bar{t}+ Z$ Cross Section in the Four Lepton Channel Using a Deep Neural Network
The production of top-quark pairs in association with a Z boson offers the opportunity to study the coupling of the Z boson to the top quark. This coupling is of interest because it is sensitive to the third component of the weak isospin and the hypercharge of the top quark. A measurement of the cou...
