Searches for new heavy quarks in ATLAS

Abstract

A search for new heavy quarks focusing on recent vector-like quark searches with the ATLAS detector at the CERN Large Hadron Collider is presented. Two recent searches targeting the pair production of type vector-like quarks are described. The first search is sensitive to vector-like up-type quark ($T$) decays to a $t$ quark and either a Standard Model Higgs boson or a $Z$ boson. The second search is primarily sensitive to $T$ decays to $W$ boson and a $b$ quark. Additionally, the results can be interpreted for alternative VLQ decays.
