The Integrated Bispectrum in Modified Gravity Theories
  Gravity-induced non-Gaussianity can provide important clues to Modified
Gravity (MG) Theories. Several recent studies have suggested using the {\it
Integrated Bispectrum} (IB) as a probe for squeezed configuration of
bispectrum. Extending previous studies on the IB, we include redshift-space
distortions to study a class of (parametrised) MG theories that include the
string-inspired Dvali, Gabadadze \& Porrati (DGP) model. Various contributions
from redshift-space distortions are derived in a transparent manner, and
squeezed contributions from these terms are derived separately. Results are
obtained using the Zel'dovich Approximation (ZA). Results are also presented
for projected surveys (2D). We use the Press-Schechter (PS) and Sheth-Torman
(ST) mass functions to compute the IB for collapsed objects that can readily be
extended to peak-theory based approaches. The {\em cumulant correlators} (CCs)
generalise the ordinary {\em cumulants} and are known to probe collapsed
configurations of higher order correlation functions. We generalise the concept
of CCs to halos of different masses. We also introduce a generating function
based approach to analyse more general non-local biasing models. The Fourier
representations of the CCs, the skew-spectrum, or the kurt-spctra are discussed
in this context. The results are relevant for the study of the Minkowski
Functionals (MF) of collapsed tracers in redshift-space.} \keywords {Cosmology,
