Probing for Ultraheavy Quanta at LHC

High Energy Physics - Phenomenology 2010-11-01 v1

Abstract

Experiments at the LHC are sensitive to the presence or absence of matter quanta at mass scales far beyond the scales they can probe directly. The production of ZZ boson pairs by gluon-gluon fusion is greatly enhanced if there are ultraheavy quanta that carry SU(3)ColorSU(3)_{\rm Color} and get their mass from electroweak symmetry breaking. For example, a fourth generation quark doublet with an arbitrarily heavy mass would induce a large excess in the ZZZZ yield that could be detected at the LHC with only 10%\simeq 10\% of the design luminosity.
