Contribution

It presents a new four-dimensional superstring formulation with specific symmetry properties and anomaly-free behavior, extending string theory frameworks.

Findings

Model is anomaly-free and ghost-free

Partition function exhibits modular invariance

Achieves effective 4D string description from higher dimensions

Abstract

A bosonic string in twenty six dimensions is effectively reduced to four dimensions by eleven Majorana fermions which are vectors in the bosonic represetation SO(d-1,1). By dividing the fermions in two groups, actions can be written down which are world sheet supersymmetric, 2-d local and local 4-d supersymmetric. The novel string is anomally free, free of ghosts and the partition function is modular invariant.
