DESCRIPTION:Models of brane inflation generate a cosmic superstring networ
 k of\nlong\, horizon-crossing strings and small\, sub-horizon loops. The\n
 tension of superstrings differ from that of field theory strings of\nthe G
 UT variety because modern compactifications lower characteristic\nenergy s
 cales at the bottom of warped throats. A network of these low\ntension str
 ings exhibits new and interesting cosmological properties.\nBelow a critic
 al string tension\, the string loops are long lived and\nthey accumulate a
 nd dominate the string network's total $\\Omega$. In\naddition\, the loops
 ' center of mass motion decays with the universe's\nexpansion and slow-mov
 ing loops will accrete along with the dark\nmatter as perturbations grow a
 nd galaxies form. The fortuitous\nconcentration of loops within our own Ga
 laxy facilitates practical\nexperimental searches for superstring loops. M
 icrolensing is a very\nsensitive means of detection.\n
