D-branes in the NS5 Near-horizon pp-Wave Background
S. F. Hassan, Rashmi R. Nayak, Kamal L. Panigrahi
A class of Dp and Dp-D(p+4)-brane solutions are constructed in the Penrose limit of the linear-dilaton geometry. The classical solutions are shown to break all space-time supersymm…
N=1 Worldsheet Boundary Couplings and Covariance of non-Abelian Worldvolume Theory
S. F. Hassan
A systematic construction is given for N=1 open string boundary coupling to Abelian and non-Abelian Dp-brane worldvolume fields, in general curved backgrounds. The basic ingredient…
D-brane Couplings, RR Fields and Clifford Multiplication
S. F. Hassan, R. Minasian
Non-trivial configurations of Yang-Mills fields and gravitational backgrounds induce charges on Dp-branes that couple them to lower and higher RR potentials. We show that these cou…
T-Duality and Non-Local Realizations of Supersymmetry in String Theory
S. F. Hassan
We study non-local realizations of extended worldsheet supersymmetries and the associated space-time supersymmetries which arise under a T-duality transformation. These non-local e…
