Description
We explore the non-commutative space-time to revive the idea that gamma-ray excess in the
galactic center can be the result of particle dark matter annihilation. In this scenario, photon
spectrum is produced by direct (prompt) emission during an annihilation where a photon can
be embed in the final state together with other direct products in a new triplet vertex. In the
various configurations of dark matter phenomenology, we adopt the most common model known
as singlet scalar. Calculating the relevant aspects of the model, we can obtain the photon flux in
the galactic center. Comparing our numerical achievements with experimental data reveals that
non-commutative space-time can be a reliable framework to explain gamma-ray excess and even
(in the future) other indirect signals of dark matter detection.
