Inflation With A Realistic SO(10) Model | | Bumseok Kyae

24 Oct 2005 | | Abstract: | We implement inflation within a realistic supersymmetric SO(10) model in which the doublet-triplet splitting is realized through the Dimopoulos-Wilczek mechanism, the MSSM $mu$ problem is resolved, and higgsino mediated dimension five nucleon decay is heavily suppressed. The cosmologically unwanted topological defects are inflated away, and from $delta T/ T$, the $B-L$ breaking scale is estimated to be of order $10^{16}-10^{17}$ GeV. Including supergravity corrections, the scalar spectral index $n_s = 0.99pm 0.01$, with $|dn_s/ d{
m ln}k| lapproxeq 10^{-3}$. | | Source: | arXiv, hep-ph/0510300 | | Services: | Forum | Review | PDF | Favorites | |
