Massive gravitons as dark matter and gravitational waves
WebJul 30, 2024 · We detailed our discovery of a chiral enhancement in the production cross sections of massive spin-2 gravitons, below the electroweak symmetry breaking scale, that makes them ideal dark matter candidates for the freeze-in mechanism. The result is independent of the physics at high scales, and points toward masses in the keV- MeV … WebFeb 12, 2024 · The Dark type (Japanese: あくタイプ Evil type) is one of the eighteen types.It was introduced in Generation II, along with the Steel type. As well as introducing … c++ string unsigned char 変換
Dark matter could be a cosmic relic from extra dimensions
WebApr 16, 2024 · So, on this front, gravitons have no problem as a dark matter candidate. When a gravitational wave passes through a location in space, it causes an expansion and a compression at alternate... WebMar 14, 2024 · 1 Answer. At a very basic level, it won't work. If gravity has a mass m, it has an effective range ℏ m c, similar to the weak interaction. This effective range must be at … WebApr 22, 2016 · We consider the possibility that the massive graviton is a viable candidate of dark matter in the context of bimetric gravity. We first derive the energy-momentum tensor of the massive graviton and show that it indeed behaves as that of dark matter fluid. We then discuss a production mechanism and the present abundance of massive gravitons … cstring ushort
