Resolving naked singularities in $$\alpha ^{\prime }$$-corrected string theory

Abstract

AbstractLow energy effective action of bosonic string theory possesses a kind of singular static solution which can be interpreted as a naked singularity. Based on the Hohm–Zwiebach action, the naked singularities could be smoothed out by introducing the complete $$\alpha ^{\prime }$$ α ′ corrections of string theory. In this paper, we present two sets of non-singular solutions, which are also regular everywhere in the Einstein frame. In the perturbative region $$\alpha ^{\prime }\rightarrow 0$$ α ′ → 0 , the solutions reduce to the perturbative results. Our result provides extra evidence for weak cosmic censorship conjecture (WCCC) from a viewpoint of string theory.
