Flaxino dark matter and stau decay
Eung Jin Chun, Hang Bae Kim, Kazunori Kohri +1
If the spontaneous breaking of Peccei-Quinn symmetry comes from soft supersymmetry breaking, the fermionic partners of the symmetry-breaking fields have mass of order the gravitino…
Solving the cosmic lithium problems with primordial late-decaying particles
Daniel Cumberbatch, Kazuhide Ichikawa, Masahiro Kawasaki +3
We investigate the modifications to predictions for the abundances of light elements from standard Big-Bang nucleosynthesis when exotic late-decaying particles with lifetimes excee…
Cosmological Constraints on Neutrino Injection
Toru Kanzaki, Masahiro Kawasaki, Kazunori Kohri +1
We derive general constraints on the relic abundances of a long-lived particle which mainly decays into a neutrino (and something else) at cosmological time scales. Such an exotic…
Possible solution to the Li problem by the long lived stau
Toshifumi Jittoh, Kazunori Kohri, Masafumi Koike +3
Modification of standard big-bang nucleosynthesis is considered in the minimal supersymmetric standard model to resolve the excessive theoretical prediction of the abundance of pri…
