Abstract
We show how the Wess-Zumino terms of the different branes in string theory
can be embedded within double field theory. Crucial ingredients in our
construction are the identification of the correct brane charge tensors {and
the use of the} double field theory potentials that arise from dualizing the
standard double field theory fields. This leads to a picture where under
T-duality the brane does not change its worldvolume directions but where,
instead, it shows different faces depending on whether some of the worldvolume
and/or transverse directions invade the winding space. As a non-trivial
by-product we show how the different Wess-Zumino terms are modified when the
brane propagates in a background with a non-zero Romans mass parameter.
Furthermore, we show that for non-zero mass parameter the brane creation
process, when one brane passes through another brane, gets generalized to brane
configurations that involve exotic branes as well.
