Description

The Standard Model with three generations of quarks describes remarkably well all particle phenomena observed to date. Although adding a fourth generation of massive fermions is an obvious extension of the model, it became less popular ever since the limit on light neutrino flavors, and the precise measurements on the electroweak parameters, seem to disfavor such a possibility. However, indirect limits can never replace direct search for heavy particles. We present the results of a search for the heavy fourth generation quark using the CMS detector in pp collisions of the Large Hadron Collider.
