Late D-term Inflation and the Cosmological Moduli Problem in TeV Scale Strings
We show that a short period of late D-term inflation can solve the
cosmological moduli (radion) problem of (asymmetric) inflation at the TeV
scale. Late inflation happens after the large compact dimensions are stabilized
which is crucial for obtaining the extremely small Hubble constant and inflaton
mass required.Comment: 12 pages in phyzzx.tex, one reference adde
M(atrix) Black Holes in Five Dimensions
We examine five dimensional extreme black holes with three charges in the
matrix model. We build configurations of the 5+1 super Yang-Mills theory which
correspond to black holes with transverse momentum charge. We calculate their
mass and entropy from the super Yang-Mills theory and find that they match the
semi-classical black hole results. We extend our results to nonextreme black
holes in the dilute gas approximation.Comment: 20 pages in phyzzx.tex, three references adde
Supergravity on and M Branes
We calculate the dimensions of operators in three and six dimensional
superconformal field theories by using the duality between these theories at
large N and D=11 supergravity on . We find that for
the duality relations to work the Kaluza--Klein masses given in the
supergravity literature must be rescaled and/or shifted.Comment: 10 pages on phyzzx.tex, typo (in eq. (20)) and TeX corrections, some
