Query: Twisted Moduli and Supersymmetry Breaking   We consider twisted moduli contributions to supersymmetry breaking in
effective type I string constructions involving intersecting D5_i and D9-branes
using Goldstino angles to parametrise the supersymmetry breaking. It is well
known that twisted moduli enter at tree-level into the gauge kinetic functions,
and can provide new sources of gaugino mass if they develop F-term vacuum
expectation values. It is generally assumed that string states which are
sequestered from the twisted moduli receive a zero soft mass in the twisted
modulus domination limit, however the standard form of Kahler potential does
not reproduce this expectation. We therefore propose a new form of the Kahler
potential which is consistent at leading order with the sequestered form
proposed by Randall and Sundrum, and show that it leads to exponentially
suppressed sequestered soft masses. Including the effects of Green-Schwarz
mixing, we write down the soft scalar masses and trilinears arising from a type
I string construction involving intersecting D5_i and D9-branes in the presence
of untwisted and twisted moduli. If the squarks and sleptons are identified
with sequestered states then in the twisted moduli dominated limit this
corresponds to gaugino mediated supersymmetry breaking, and we discuss two
different scenarios for this. The general results will be useful for
phenomenological studies involving a combination of gravity and gaugino
mediated SUSY breaking due to the dilaton, untwisted and twisted moduli
contributions, and enable the soft masses to be studied as a function of the
different compactification radii.
