Type IIB 2-form Fields and Gauge Coupling Constant of 4D N=2 super QCD
Takuhiro Kitao
We study the relation between the Type IIB (NSNS and RR) 2-form fields and the (complex) gauge coupling constant of the 4D N=2 SU(Nc) super Yang-Mills theory with Nf fundamental ma…
Spectrum of Maxwell-Chern-Simons Theory Realized on Type IIB Brane
Takuhiro Kitao, Nobuyoshi Ohta
We study the 3D field theory on one D3-brane stretched between (r,s) and (p,q)5-branes. The boundary conditions are determined from the analysis of NS5 and D5 charges of the two 5-…
Three-Dimensional Gauge Dynamics from Brane Configurations with (p,q)-Fivebrane
Takuhiro Kitao, Kazutoshi Ohta, Nobuyoshi Ohta
We study three-dimensional gauge dynamics by using type IIB superstring brane configurations, which can be obtained from the M-theory configuration of M2-branes stretched between t…
Fermionic Zero Mode and String Creation between D4-Branes at Angles
Takuhiro Kitao, Nobuyoshi Ohta, Jian-Ge Zhou
We study the creation of a fundamental string between D4-branes at angles in string theory. It is shown that part of the one-loop potential of open string changes its s…
N=2 Curves and a Coulomb Phase in N=1 SUSY Gauge Theories with Adjoint and Fundamental Matters
T. Kitao, S. Terashima, S. -K. Yang
We study low-energy effective superpotentials for the phase with a confined photon in N=1 supersymmetric gauge theories with an adjoint matter and fundamental flavors $Q, \tild…
SUSY N=2 hyperelliptic curve from N=1 effective potential
Takuhiro Kitao
We derive the singularity conditions of the N=1 generalized (general yukawa couplings and quark masses) form of hyperelliptic curves of SU(N_c) with N_f flavors. The results reprod…
