A measurement of the top-quark mass and the ttZ cross section is performed using 4.6 fb^-1 and 20.3 fb^-1 of data from proton-proton collisions collected ...

The top quark is the heaviest of the known fundamental particles in the Standard Model (SM) with a mass of 173.3±1.1GeV. It is the sixth quark in the SM and the weak isospin partner of the bottom quark. Properties such as ......
