abstract = {Galaxy clusters are expected to be dark matter (DM)
reservoirs and storage rooms for the cosmic-ray protons
(CRp) that accumulate along the cluster's formation history.
Accordingly, they are excellent targets to search for
signals of DM annihilation and decay at gamma-ray energies
and are predicted to be sources of large-scale gamma-ray
emission due to hadronic interactions in the intracluster
medium. We estimate the sensitivity of the Cherenkov
Telescope Array (CTA) to detect diffuse gamma-ray emission
from the Perseus galaxy cluster. We perform a detailed
spatial and spectral modelling of the expected signal for
the DM and the CRp components. For each, we compute the
expected CTA sensitivity. The observing strategy of Perseus
is also discussed. In the absence of a diffuse signal
(non-detection), CTA should constrain the CRp to thermal
energy ratio within the radius $R_{500}$ down to about
$X_{500}<3\times 10^{-3}$, for a spatial CRp distribution
that follows the thermal gas and a CRp spectral index
$\alpha_{\rm CRp}=2.3$. Under the optimistic assumption of a
pure hadronic origin of the Perseus radio mini-halo and
depending on the assumed magnetic field profile, CTA should
measure $\alpha_{\rm CRp}$ down to about $\Delta\alpha_{\rm
CRp}\simeq 0.1$ and the CRp spatial distribution with 10\%
precision. Regarding DM, CTA should improve the current
ground-based gamma-ray DM limits from clusters observations
on the velocity-averaged annihilation cross-section by a
factor of up to $\sim 5$, depending on the modelling of DM
halo substructure. In the case of decay of DM particles, CTA
will explore a new region of the parameter space, reaching
models with $\tau_{\chi}>10^{27}$s for DM masses above 1
TeV. These constraints will provide unprecedented
sensitivity to the physics of both CRp acceleration and
transport at cluster scale and to TeV DM particle models,
especially in the decay scenario.},
