Heterotic Action in SUGRA-SYM Background
Jaemo Park, Cheol Ryou, Woojoo Sim
We consider the generalization of the heterotic action considered by Cherkis and Schwarz where the chiral bosons are introduced in a manifestly covariant way using an auxiliary fie…
D-instanton derivation of multi-fermion F-terms in supersymmetric QCD
Yoshinori Matsuo, Jaemo Park, Cheol Ryou +1
We investigate effects of field theory instantons by considering D-instantons in a suitable D3-brane background. In supersymmetric QCD with SU(N_c) gauge group with N_f=N_c flavors…
Chiral primary cubic interactions from pp-wave supergravity
Youngjai Kiem, Yoonbai Kim, Jaemo Park +1
We explicitly construct cubic interaction light-cone Hamiltonian for the chiral primary system involving the metric fields and the self-dual four-form fields in the IIB pp-wave sup…
One-loop Noncommutative U(1) Gauge Theory from Bosonic Worldline Approach
Youngjai Kiem, Yeonjung Kim, Cheol Ryou +1
We develop a method to compute the one-loop effective action of noncommutative U(1) gauge theory based on the bosonic worldline formalism, and derive compact expressions for N-poin…
Duality and Enhanced Gauge Symmetry in 2+1 Dimensions
Taichi Itoh, Phillial Oh, Cheol Ryou
We investigate the enlarged CP(N) model in 2+1 dimensions. This is a hybrid of two CP(N) models coupled with each other in a dual symmetric fashion, and it exhibits the gauge symme…
Gauge Symmetry Enhancement and Radiatively Induced Mass in the Large N Nonlinear Sigma Model
Taichi Itoh, Phillial Oh, Cheol Ryou
We consider a hybrid of nonlinear sigma models in which two complex projective spaces are coupled with each other under a duality. We study the large N effective action in 1+1 dime…
