Matrix string theory, contact terms, and superstring field theory

Click For Summary
A recent paper presents new insights into second quantized string field theory, suggesting promising implications for future models. The initial evaluation indicates the findings are robust, though further inquiries are anticipated. There is interest in obtaining clearer explanations for certain matrix theory concepts discussed in the paper, particularly regarding "irrelevant fields" and their scaling arguments. The discussion emphasizes the need for foundational understanding before delving deeper into complex topics. Overall, the paper is viewed positively, with expectations for ongoing exploration and clarification.

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" Oni and the scaling argument surrounding them.
 
The expression learn to crawl before attempting to sprint comes to mind.
 

Thread 'Questioning the timescape model'

"Supernovae evidence for foundational change to cosmological models" https://arxiv.org/pdf/2412.15143 The paper claims: We compare the standard homogeneous cosmological model, i.e., spatially flat ΛCDM, and the timescape cosmology which invokes backreaction of inhomogeneities. Timescape, while statistically homogeneous and isotropic, departs from average Friedmann-Lemaître-Robertson-Walker evolution, and replaces dark energy by kinetic gravitational energy and its gradients, in explaining...
