Towards non-Archimedean superstrings

An action for a prospect of a p-adic open superstring on a target Minkowski space is proposed. The action is constructed for ‘worldsheet’ fields taking values in the p-adic field Qp, but it is assumed to be obtained from a discrete action on the Bruhat-Tits tree.

Description
Summary:An action for a prospect of a p-adic open superstring on a target Minkowski space is proposed. The action is constructed for ‘worldsheet’ fields taking values in the p-adic field Qp, but it is assumed to be obtained from a discrete action on the Bruhat-Tits tree. This action is proven to have an analogue of worldsheet supersymmetry and the superspace action is also constructed in terms of superfields. The action does not have conformal symmetry, however it is implemented in the definition of the amplitudes. The tree-level amplitudes for this theory are obtained for N vertex operators corresponding to tachyon superfields and a Koba-Nielsen formula is obtained. Finally, four-point amplitudes are computed explicitly and they are compared to previous work on p-adic superstring amplitudes.
