dc.description.resumoIn this work, we briefly review the main ingredients of the Standard Model of particle physics and lay the groundwork for dark matter physics. Although not yet detected, the existence of dark matter is strongly supported by numerous observational evidence in astrophysics. By assuming fundamental characteristics of dark matter particles, inferred from their observed effects, we consider a specific candidate and describe the detection strategies for this case. In particular, we investigate the indirect detection method using gamma-ray lines produced by dark matter annihilation, which are one of the most robust and distinct signals of dark matter, providing a direct window into the nature of its interactions. We develop a framework based on effective field theory to describe the annihilation of dark matter particles into photons and study the detectability of these signals using the Fermi Large Area Telescope (Fermi-LAT) and the High Energy Stereoscopic System (H.E.S.S.) telescopes to constrain the parameter space of these effective dark matter interactions. Our results demonstrate that gamma-ray lines can probe dark matter interactions up to the TeV scale, contributing to the ongoing effort to understand the particle nature of dark matter.pt_BR
