Inflation on a Pair of D3-brane and D3bar-brane in Klebanov-Strassler Background
Yoonbai Kim, Hiroaki Nakajima, Kyungha Ryu +1
We explain how to obtain Klabanov-Strassler solution in the low-energy limit of type IIB superstring theory and describe slow-roll inflation on the system of parallely-separated D3…
Vortex-type Half-BPS Solitons in ABJM Theory
Chanju Kim, Yoonbai Kim, O-Kab Kwon +1
We study Aharony-Bergman-Jafferis-Maldacena (ABJM) theory without and with mass deformation. It is shown that maximally supersymmetry preserving, D-term, and F-term mass deformatio…
Instanton Calculus in R-R 3-form Background and Deformed N=2 Super Yang-Mills Theory
Katsushi Ito, Hiroaki Nakajima, Shin Sasaki
We study the ADHM construction of instantons in N=2 supersymmetric Yang-Mills theory deformed in constant Ramond-Ramond (R-R) 3-form field strength background in type IIB superstri…
Quantum SUSY Algebra of -lumps in the Massive Grassmannian Sigma Model
Hiroaki Nakajima, Phillial Oh, Sunyoung Shin
We compute the SUSY algebra of the massive Grassmannian sigma model in 2+1 dimensions. We first rederive the action of the model by using the Scherk-Schwarz dimensi…
Instantons in Deformed Super Yang-Mills Theories
Shin Sasaki, Katsushi Ito, Hiroaki Nakajima
We study the instanton effective action in deformed four-dimensional N=2 and N=4 super Yang-Mills (SYM) theories. These deformed gauge theories are defined on the D-brane world-vol…
1/N Expansion of the 2D CP^{N-1} Model on Non(anti)commutative Superspace
Kazutoshi Araki, Takeo Inami, Hiroaki Nakajima +1
We study UV properties of the two-dimensional supersymmetric CP^{N-1} model on non(anti)commutative superspace. We show that the deformed model has the same UV property as the ordi…
