Matrix string theory, contact terms, and superstring field theory

[ranyart]

A recent paper details some new insights for the second quantized
string field theory.

This has some implications for future models, it appears to be quite sound, but this is based on a confined early viewpoint of a first once over reading, no doubt there will be more questions to follow.

Very nice paper. I wonder if we could get some "Baez type" explanations of some of the matrix theory statements in the paper. They don't seem impossibly deep, but I for one could use some context with them. For starters, how about the "irrelevant fields" O^n_i and the scaling argument surrounding them.
