Supersymmetric inflation and baryogenesis via Extra-Flat directions of the MSSM
John McDonald, Osamu Seto
One interpretation of proton stability is the existence of extra-flat directions of the MSSM, in particular and , where the operators lifting the poten…
Neutralino dark matter from heavy axino decay
Ki-Young Choi, Jihn E. Kim, Hyun Min Lee +1
We consider cosmological consequences of a heavy axino, decaying to the neutralino in R-parity conserving models. The importance and influence of the axino decay on the resultant a…
Gravitino dark matter from increased thermal relic particles
Nobuchika Okada, Osamu Seto
We investigate the so-called superWIMP scenario with gravitino as the lightest supersymmetric particle (LSP) in the context of non-standard cosmology, in particular, brane world co…
Axino warm dark matter and coincidence
Osamu Seto, Masahide Yamaguchi
We show that axinos, which are dominantly generated by the decay of the next-to-lightest supersymmetric particles produced from the leptonic -ball (-ball), become warm dark m…
The Effect of Extra Dimension on Dark Matter
Nobuchika Okada, Osamu Seto
We investigate the thermal relic density of a cold dark matter in the brane world cosmology. Since the expansion law in a high energy regime is modified from the one in the standar…
