Description
Searches for vector-like quarks are motivated by Composite Higgs models assuming a new strong sector and predict the existence of new heavy resonances. A search for single production of vector-like quarks is performed for the through the exchange of a heavy gluon in the $p p \to G^* \to B\bar b/\bar B b \to H b \bar b \to b~\bar b~b~\bar b$ process, where $G^*$ is a heavy color octet vector resonance and $B$ a vector-like quark of charge -1/3. The largest background, QCD multi-jet, is estimated using a data-driven method. In case of no excess of events, upper limits on the production cross sections and lower limits in the 2D plane {m_G^*, m_B} will be set.
