We study a two-component dark matter model consisting of a Dirac fermion and a complex scalar charged under new U(1) gauge group in the hidden sector. The dark fermion plays the dominant component of dark matter which explains the measured DM relic density of the Universe. It has no direct coupling to ordinary standard model particles. thus evading strong constraints from the direct D... https://www.diegojavierfares.com/best-price-Vinyl-Wall-Decal-Sticker-Gymnastic-Rings-815-quick-super/
