The effective theory realizes minimal but essential features of DM predicted in extra-dimension models, and enables to systematically treat non-perturbative corrections such as the Sommerfeld effects. Deriving an annihilation cross section including the Sommerfeld effects based on the effective theory, the author discusses the future sensitivity of observations to gamma-ray from the Galactic Center. As a result, the author explains the monochromatic gamma-ray signatures originate from two photons (γγ) or photon and Z boson (γZ) produced in the process of DM annihilations, and concludes a possible scenario that unstable neutral spin-1 particles (Z’) appear and results in a spectral peak in addition to the one caused by γγ and γZ channels in gamma-ray observations. If those two spectral peaks are observed, the masses of spin-1 DM and Z’ would be reconstructed.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5061Dark matter (Astronomy)Nuclear spinParticles (Nuclear physics)Dark matter (Astronomy)Nuclear spin.Particles (Nuclear physics)523.1126Fujiwara Motoko1355316MiAaPQMiAaPQMiAaPQ9910720060403321Electroweak-Interacting Spin-1 Dark Matter and Its Phenomenology3359441UNINA
