The effective action of a BPS Alice string
Abstract Recently a BPS Alice string has been found in a $$U(1)\times SO(3)$$ U ( 1 ) × S O ( 3 ) gauge theory coupled with three charged complex scalar fields in the triplet representation (in JHEP 1709:046 arXiv:1703.08971 [hep-th], 2017). It is a half BPS state preserving a half of the supercharg...

| Summary: | Abstract Recently a BPS Alice string has been found in a $$U(1)\times SO(3)$$ U ( 1 ) × S O ( 3 ) gauge theory coupled with three charged complex scalar fields in the triplet representation (in JHEP 1709:046 arXiv:1703.08971 [hep-th], 2017). It is a half BPS state preserving a half of the supercharges when embedded into a supersymmetric gauge theory. In this paper, we study zero modes of a BPS Alice string. After presenting U(1) and translational zero modes, we construct the effective action of these modes. In contrast to a previous analysis of the conventional Alice string for which only large distance behaviors are known, we can exactly perform a calculation in the full space thanks to the BPS properties. |
