abstract = {Galaxy clusters are expected to be both 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 γ-ray energies and
are predicted to be sources of large-scale γ-ray emission
due to hadronic interactions in the intracluster medium
(ICM).In this paper, we estimate the sensitivity of the
Cherenkov Telescope Array (CTA) to detect diffuse γ-ray
emission from the Perseus galaxy cluster.We first perform a
detailed spatial and spectral modelling of the expected
signal for both the DM and the CRp components. For each
case, we compute the expected CTA sensitivity accounting for
the CTA instrument response functions. The CTA observing
strategy of the Perseus cluster is also discussed.In the
absence of a diffuse signal (non-detection), CTA should
constrain the CRp to thermal energy ratio X$_{500}$ within
the characteristic radius R$_{500}$ down to about X$_{500}$
< 3 × 10$^{-3}$, for a spatial CRp distribution that
follows the thermal gas and a CRp spectral index α$_{CRp}$
= 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
α$_{CRp}$ down to about Δα$_{CRp}$ ≃ 0.1 and the CRp
spatial distribution with 10\% precision, respectively.
Regarding DM, CTA should improve the current ground-based
γ-ray DM limits from clusters observations on the
velocity-averaged annihilation cross-section by a factor of
up to ∼ 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 τ$_{χ}$ > 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.},
