Electroweak-Interacting Spin-1 Dark Matter and Its Phenomenology
Book information
Description
This book offers construction of a renormalizable effective theory of electroweak-interacting spin-1 dark matter (DM). 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.

The arraignment and tryall with a declaration of the Ranters also, several sentences proceedings at the sessions in the Old-Baily, and Councel of War: their protestations and the hanging of one up by the thumbs; with divers penalties to be inflicted upon others. The dancing and revelling of Dr. Buckeridge and his wife, and other gent. dancing all in white, in Berkshire, and their Christmas carol. A dispute between a Ranter in Bridewel, and one that came to see him; with his creed and pater noster: and the names of the false gods they worship. As also, a list of many of the Ranters, from whence they are derived: and of many hundreds of them in England
