Another interesting example is the top momentum reconstruction. We compare in what follows the reconstructed top momentum distribution with calorimetric information only and that with the new combined track information for with and .
Fig.3.5 compares the residual distributions of
top momentum reconstruction with only calorimetric (left) and combined
track information (right).
When projected to the vertical axis, the difference becomes
clear (see Fig.3.6).
We can see a significant improvement of momentum resolution. It should also be noted that the systematic shift of the center value also gets smaller when the combined track information is used as seen in Fig.3.7
