Descripción
Recent measurements by the ATLAS Collaboration of b- and light jet shapes in ttbar final states at the LHC, show clear evidence that b-jets are wider. There is also evidence that b-jets in ttbar final states are narrower than those produced inclusively. This can be interpreted as due to the two different colour structures considered. We apply multivariate techniques on MC generated data to illustrate possible applications of these observations to i) measurement of |Vts| and ii) separation of H->bbar in association with a Z from the background process Z+bbar.
The lessons to be learned is that jet shape measurements show more potential in the former case than in the latter.
