Circumventing the No-Go Theorem in Noncommutative Gauge Field Theory
Masato Arai, Sami Saxell, Anca Tureanu +1
Stringent restrictions for model building are imposed by a no-go theorem in noncommutative gauge field theory. Circumventing this theorem is crucial for the construction of realist…
Projective superspace and hyperkahler sigma models on cotangent bundles of Hermitian symmetric spaces
Masato Arai, Sergei M. Kuzenko, Ulf Lindstrom
We review the projective-superspace construction of four-dimensional N=2 supersymmetric sigma models on (co)tangent bundles of the classical Hermitian symmetric spaces.
Meta-stable Vacuum in Spontaneously Broken N=2 Supersymmetric Gauge Theory
Masato Arai, Claus Montonen, Nobuchika Okada +1
We consider an N=2 supersymmetric SU(2) \times U(1) gauge theory with N_f=2 massless flavors and a Fayet-Iliopoulos (FI) term. In the presence of the FI term, supersymmetry is spon…
Top quark spin correlations in the Randall-Sundrum model at the CERN Large Hadron Collider
Masato Arai, Nobuchika Okada, Karel Smolek +1
In the Randall-Sundrum model, we study top-antitop pair production and top spin correlations at the Large Hadron Collider. In addition to the Standard Model processes, there is a n…
