The Hosotani Mechanism in Bulk Gauge Theories with an Orbifold Extra Space S^1/Z_2
Masahiro Kubo, C. S. Lim, Hiroyuki Yamashita
We pursue the possibility of the scenario in which the Higgs field is identified with the extra-space component of a bulk gauge field. The space-time we take is M S…

Constraints on Non-Holomorphic correction in N=2 superspace
Hiroyuki Yamashita
We study quantum corrections on four derivative term of vector multiplets in supersymmetric Yang-Mills theory. We first show splitting of quantum correction on gauge…

A Simple Proof of the Non-Renormalization of the Chern-Simons Coupling
Makoto Sakamoto, Hiroyuki Yamashita
We give a very simple proof that the renormalization of the Chern-Simons coupling in the Wilsonian effective action is exhausted at one-loop. Our proof can apply to arbitrary 2+1-d…
