Sparticle searches with CMS at LHC

In this paper a review of recent studies made to understand the capability to detect and reconstruct strongly interacting squarks and gluinos with the CMS detector is presented. The detection of these sparticles relies on the observation of an excess of events over Standard Model background expectations. The results for inclusive searches of squarks and gluinos are presented as 5σ discovery contours in the framework of a minimal SU(5) mSUGRA model. A new study devoted to the scalar bottom quark (b̃) and gluino (g̃) reconstruction, through the process g̃ → b̃b, will be discussed extensively and the expected resolutions on sbottom and gluino masses are presented.
