Standard Model Physics at CMS

The LHC will provide proton-proton collisions at energies of about 14 TeV and at a rate of about 40 MHz. It will be possible to observe new physics but also to have precise measurements of Standard Model phenomena. CMS is a general purpose detector which is designed to detect and measure the properties of the particles in the final state of these collisions. Some chosen results expected within domains like top quark physics, electro-weak physics, gauge boson couplings and B physics are presented here. With the high rate and energy, some new proscesses from the Standard Model, as for example single top, will become visible.
