Measurement of the W helicity in top quark decays with the ATLAS detector using a template method

Mostrar otras versiones (1)

Using 35 pb-1 of data, recorded in 2010, ATLAS has measured the helicity of the W-boson in top quark decays in the lepton+jet channel of ttbar events. The analysis uses a likelihood kinematic fitter for the event reconstruction and extracts the helicity contributions via template fits to the helicit...
