The search results for "hep-lat" primarily discuss debates and responses related to theoretical work in high energy physics, string theory, and quantum field theory within the hep-th (high-energy physics - theory) category. Key points include ongoing discussions about the validity of certain claims, such as the universality of the Polchinski-Strominger effective string model spectrum (hep-th/0411017, hep-th/0606265), and the existence of higher-order terms in effective string theories (hep-th/0608109). Additionally, there is mention of related works and critiques in quantum gravity and cosmology contexts, as well as incomplete manuscripts and book drafts based on extensive research (e.g., Æthereal Multiverse).

Reply to hep-th/0606265

In hep-th/0411017 the Polchinski-Strominger effective string model was examined and it was shown there that the spectrum of excitations is universal up to and including terms of order $R^{-3}$ in the long distance expansion. Subsequently the same result was claimed in hep-th/0606265 where certain cr…

Our response to the response hep-th/0608109 by Drummond

We have carefully examined all the points raised by Drummond in his response hep-th/0608109 to our paper hep-th/0606265 wherein we had made some criticisms of his earlier work hep-th/0411017. We concede that Drummond is correct in claiming the non-existence of R^{-4} and R^{-5} order effective strin…

Reply to arXiv:0711.4930[hep-th] by Ito and Seiler

In a recent note (arXiv:0711.4930[hep-th]) Ito and Seiler claim that there is a 'missing link' in the derivation in arXiv:0707.2179[hep-th] by the present author; namely, that no proof of a certain inequality used there is given at weak coupling. Here it is pointed out that in fact no such missing l…

This is a reply to the above comment (hep-th/9509028). We argue that QED displays a class of symmetries which may be used to select out the various velocity dependent superselection sectors.…

Comment on ``PT-Symmetric versus Hermitian Formulations of Quantum Mechanics [hep-th/0511229]''

We explain why the main conclusion of Bender et al, hep-th/0511229 [J. Phys. A 39 (2006) 1657] regarding the practical superiority of the non-Hermitian description of PT-symmetric quantum systems over their Hermitian description is not valid. Recalling the essential role played by the Hermitian desc…
