Tadpole Resummations in String Theory
Noriaki Kitazawa
While R-R tadpoles should be canceled for consistency, string models with broken supersymmetry generally have uncanceled NS-NS tadpoles. Their presence signals that the background…
Physical auxiliary field in supersymmetric QCD with explicit supersymmetry breaking
Noriaki Kitazawa
It is shown that the auxiliary field in the low-energy effective theory of the supersymmetric QCD (SU(N_c) gauge symmetry with flavors N_f < N_c) can be understood as a physical de…
Towards exact results of QED from supersymmetry
Masato Arai, Noriaki Kitazawa
To obtain some exact results of U(1) gauge theory (QED), we construct the low energy effective action of N=2 supersymmetric QED with a massless matter and Fayet-Iliopoulos term, as…
Towards Deriving Higgs Lagrangian from Gauge Theories
Noriaki Kitazawa, Francesco Sannino
A new method of deriving the Higgs Lagrangian from vector-like gauge theories is explored. After performing a supersymmetric extension of gauge theories we identify the auxiliary f…
Higgs Lagrangian from Gauge Theories
N. Kitazawa, F. Sannino
We explore a novel way of deriving the effective Higgs Lagrangian from strongly interacting vector-like gauge theories. We consider the N=1 supersymmetric extension of gauge theori…
An Analysis on a Supersymmetric Chiral Gauge Theory with No Flat Direction
Noriaki Kitazawa
A guiding principle to determine the Kaehler potential in the low energy effective theory of the supersymmetric chiral gauge theory with no flat direction is proposed. The guiding…
