ATLAS on-Z excess through vector-like quarks

ATLAS on-Z excess through vector-like quarks

We investigate the possibility that the excess observed in the leptonic-Z+jets+E̸T ATLAS SUSY search is due to productions of vector-like quarks U, which decay to the first-generation quarks and Z bosons. We find that the excess can be explained within the 2σ (up to 1.4σ) level with satisfying the c...
