Description
Among the places to look for deviations from the SM are new quarks families that can appear as a fourth
family with Higgs, a “strong” fourth family without Higgs or vector-like
quarks. A potential extension for the SM would be the adjonction a 4th family of
heavy chiral fermions that could provide new sources of CP violation to
explain the matter-antimatter asymmetry in the Universe, and allow
for a heavier Higgs boson while remaining consistent with other precision
electroweak studies. This poster will review various searches for 4th generation quarks
performed using data collected in 7 TeV LHC proton-proton collisions with the ATLAS detector.
