High Energy Physics - Theory 2014-07-02 v2

Abstract

We construct yet another N=(4,4){\mathcal N}=(4,4) gauged linear sigma model for the ANA_N-type ALE space. In our construction the toric data of the ALE space are manifest. Due to the SU(2)RSU(2)_R symmetry, the F-term is automatically determined. The toric data, which govern the K\"{a}hler structures of the ALE space, are embedded into U(1)U(1) charges of charged hypermultiplets. The F-term is also inevitable to determine the complex structures of the ALE space. In the IR limit, we obtain the K\"{a}hler potential of the ANA_N-type ALE space. We also find the origin of the ZN+1{\mathbb Z}_{N+1} orbifold symmetry in the singular limit of the ANA_N-type ALE space. In a special case, we reproduce an explicit form of the K\"{a}hler potential of the A1A_1-type ALE space, i.e., the Eguchi-Hanson space.
