  Can pure-bosonic string theories exist in curved spacetime?

+ 4 like - 0 dislike
1364 views

Question: Can there be a consistent non-supersymmetric pure-bosonic string theory in some curved spacetimes?

Reason: Since fields with certain amount of negative mass can exist in curved spacetime (cf. the Breitenlohner-Freedman bound in AdS) and since avoiding ground-state tachyons of pure-bosonic strings in flat spacetime seems to be the main motivation (besides phenomenological reasons) for superstrings in flat spacetime.

Extending this, are there examples of consistent AdS/CFT dualities involving pure-bosonic fields in the bulk?

Interesting question. For some examples of non-SUSY AdS/CFT examples that rely on the validity of the BF bound, try e.g. arxiv.org/abs/hep-th/0105047 - a problem is that the paper is in "SUGRA" only. The critical dimensions aren't imposed in general and the CFTs are only described rather vaguely by some operators and properties.

@LubošMotl That paper seems to be squarely on this. Thanks!! Will look into that.
