Abstract
Recent measurements by the ATLAS Collaboration of b- and light jet-shapes in tt‾ final states at the LHC, show clear evidence that b-jets are wider. There are also indications that b-jets in tt‾ final states are narrower than those produced inclusively. We apply multivariate analysis techniques on MC generated samples to illustrate possible applications of these observations in two study cases: 1) measurement of |Vts| and 2) separation of pp→ZH→l+l−bb‾ from the continuum background i.e. pp→Z+bb‾→l+l−+bb‾. The lesson to be learned is that jet shape measurements show more potential in the former case than in the latter.
