Query: Top Quark Rare Decays via Loop-Induced FCNC Interactions in Extended
  Mirror Fermion Model   Flavor changing neutral current (FCNC) interactions for a top quark $t$
decays into $Xq$ with $X$ represents a neutral gauge or Higgs boson, and $q$ a
up- or charm-quark are highly suppressed in the Standard Model (SM) due to the
Glashow-Iliopoulos-Miami mechanism. Whilst current limits on the branching
ratios of these processes have been established at the order of $10^{-4}$ from
the Large Hadron Collider experiments, SM predictions are at least nine orders
of magnitude below. In this work, we study some of these FCNC processes in the
context of an extended mirror fermion model, originally proposed to implement
the electroweak scale seesaw mechanism for non-sterile right-handed neutrinos.
We show that one can probe the process $t \to Zc$ for a wide range of parameter
space with branching ratios varying from $10^{-6}$ to $10^{-8}$, comparable
with various new physics models including the general two Higgs doublet model
with or without flavor violations at tree level, minimal supersymmetric
standard model with or without $R$-parity, and extra dimension model.
