2.4.2 Direct detection
The XENON1T [18] experiments have a strong sensitivity for spin-independent and spindependent DM-nucleon interactions in our interested mass range of DM. However, recent data from LZ [22] and XENONnT [24] have further put stronger bounds on scattering cross-section. The interaction between DM (𝑁1) and a quark (q) can be described by the following effective Lagrangian:
\
2.4.3 Indirect detection
\ These gamma rays would be produced preferentially in regions of high DM density and can be best detected by Fermi-Lat [8], HESS [7]. The integrated gamma-ray flux from the DM annihilation in a density distribution 𝜌(r) is given by
