Abstract
Top quark events resulting from proton-proton collisions at high
energies in the new Large Hadron Collider
will be collected by the CMS experiment and have the potential to
probe New Physics beyond the Standard Model,
besides providing callibration of the detector.
The study of the production and decay of the Top quarks might reveal
high-mass resonances, extra-dimensions, new flavor dynamics,
and evidence for a 4$^{th}$ generation, among other possibilities.
Specific experimental techniques for event reconstruction and for the
control of the background are required to increase the reach for New Physics.
An overview of some of these techniques is given along with the
expected sensitivity of the CMS experiment for possible startup scenarios.
A focus on the measurement of the Heavy Flavor Content of the
$t\bar{t}$ sample is given as a example search for evidence of New Physics
which can be performed with the first data to be acquired by the CMS experiment.
