  We investigate non-inertial effects on $CP$-violating processes using a
model, based on the framework of quantum field theory in curved spacetimes,
devised to account for the decay of accelerated particles. We show that the
$CP$ violation parameter for the decay of accelerated kaons into two pions
decreases very slightly as very high accelerations are achieved, implying
decreased asymmetry between matter and antimatter in this regime. We discuss
the relationship between these results and cosmological processes surrounding
matter-antimatter asymmetry and argue that, due to the connection between
non-inertial and thermal phenomena established by the Unruh effect, this kind
of computation may prove useful in furthering the understanding of
thermodynamical effects in curved spacetimes.
