abstract = "We investigate the propagation of primordial gravitational waves
within the context of the Horndeski theories, for this, we present
a generalized transfer function quantifying the sub-horizon
evolution of gravitational waves modes after they enter the
horizon. We compare the theoretical prediction of the modified
primordial gravitational waves spectral density with the aLIGO,
Einstein telescope, LISA, gLISA and DECIGO sensitivity curves.
Assuming reasonable and different values for the free parameters
of the theory (in agreement with the event GW170817 and stability
conditions of the theory), we note that the gravitational waves
amplitude can vary significantly in comparison with general
relativity. We find that in some cases the gravitational
primordial spectrum can cross the sensitivity curves for DECIGO
detector with the maximum frequency sensitivity to the theoretical
predictions around 0.05 - 0.30 Hz. From our results, it is clear
that the future generations of space based interferometers can
bring new perspectives to probing modifications in general
relativity.",
