Macroscopic strings as heavy quarks in large N gauge theory and Antide Sitter supergravity
 PHYS. J. C22
"... Maldacena has put forward large N correspondence between superconformal field theories on the brane and antide Sitter supergravity in spacetime. We study some aspects of the correspondence between N = 4 superconformal gauge theory on D3brane and maximal supergravity on adS5 × S5 by introducing mac ..."

potential and again find agreements between the gauge theory and the supergravity results. By turning on RamondRamond zeroform potential, we also study θ vacuum angle dependence of the static potential. We finally discuss dynamical realization of loop equation via turning on local electric field
N=2 Sigma Models for RamondRamond Backgrounds
, 2002
"... manifestly N=(2,2) worldsheet supersymmetric sigma models are constructed for the Type IIB superstring in RamondRamond backgrounds. The Kahler potential in these N=2 sigma models depends on four chiral and antichiral bosonic superfields and two chiral and antichiral fermionic superfields. When the ..."

, 2001
"... Abstract: We propose the leading couplings, in an α ′ expansion, of Dbranes to RamondRamond (RR) potentials in a constant NSNS Bfield for an arbitrary choice of noncommutative parameter. The proposal is motivated by some string amplitude computations. The zero momentum couplings are topological i ..."

RamondRamond couplings of nonBPS Dbranes ∗
, 1999
"... We study how nonBPS type II Dbranes couple to RR potentials. Upon tachyon condensation the couplings we find give rise to the WessZumino action of BPS Dbranes. In a seminal series of papers, Sen has shown how to obtain an exact conformal field theory description of nonBPS Dbranes (see [1] for ..."

dimensional branes. For type IIB this was demonstrated by Witten in [2], where all branes are built from sufficiently many D9–antiD9 pairs. As to type IIA, Horava outlined the construction of lower branes from nonBPS D9branes [3]. As is wellknown, type II BPS Dbranes couple to RamondRamond gauge fields through

, 2008
"... We consider string theory in maximally supersymmetric type IIB plane wave background with constant five form RamondRamond flux (RR plane wave). It is argued that there exists a universal sector of string configurations independent of the null coordinate x − such that the spacetime action evaluated ..."

, 2004
"... Abstract: We study the physics of D–branes in the presence of constant Ramond–Ramond potentials. In the string field theory context, we first develop a general formalism to analyze open strings in gauge trivial closed string backgrounds, and then apply it both to the RNS string and within Berkovits ..."

"... Inspired by a work of Brace, Morariu and Zumino, we give a simple proof that the type IIA/IIB effective actions compactified on T d are generically invariant under the Tduality group SO(d, d;Z) when RR potentials are combined suitably with NSNS 2form and transform as a MajoranaWeyl spinor of SO ..."

RAMONDRAMOND FIELDS, FRACTIONAL BRANES AND ORBIFOLD DIFFERENTIAL KTHEORY
, 2007
"... We study Dbranes and RamondRamond fields on global orbifolds of Type II string theory with vanishing Hflux using methods of equivariant Ktheory and Khomology. We illustrate how Bredon equivariant cohomology naturally realizes stringy orbifold cohomology. We emphasize its role as the correct co ..."
