Description
Just as renormalizable Simplified Models can be used alongside of
effective field theories for the study of dark matter interactions, Simplified
Models can be used to describe new physics associated with
the Higgs boson. The objective is for the Simplified Model to
capture some of the new Higgs physics associated with a wide
range of UV-complete theories. Such models allow for variations in the
tree-level and loop-induced Higgs couplings in a somewhat uncorrelated
manner, and necessarily predict the existence of new 'mediator' particles
that can searched for at the LHC and elsewhere. Here we present a simple
example of one such model that employs both a vector-like, isosinglet top
quark and a new isosinglet scalar, that generates the new quark
mass as well as coupling to the 125 GeV Higgs. In this work the detailed
phenomenology of this Simplified Model is examined in detail.
