Academic Synthesis
The collection of scholarly papers highlights ongoing debates and refinements in theoretical physics, particularly in string theory and quantum field theory. Drummond's work, scrutinized by Hari Dass and Matlock, centers on the universality of the Polchinski-Strominger effective string model and the emergence of higher-order terms, with both sides agreeing on the absence of certain terms in the parity-conserving sector but diverging on their existence in the parity-violating sector. Glinka's draft further expands on quantum cosmology and quantum gravity, indicating a broad exploration of Lorentz symmetry violation across various theoretical frameworks. Meanwhile, Tomboulis addresses accusations of a missing link in a derivation concerning inequalities at weak coupling, reinforcing the robustness of his original arguments. Collectively, these discussions underscore the dynamic nature of theoretical physics, where iterative critique and clarification refine understanding and advance the field.
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 criticisms of the earlier work were made. In this note we demonstrate that the criticisms are wrong and the methods and results of the earlier work are perfectly correct. In particular we address the issue of higher order corrections to the action and show that they were correctly given already in hep-th/0411017.
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 string actions in the parity conserving sector, though only insofar as equivalence of field theories is considered at the classical level; the situation in unclear when quantum equivalence is taken into consideration. We still maintain the existence of such terms in the parity violating sector. Nevertheless we point out that all this has no consequence for our original proof of the nonexistence of order-R^{-3} terms. Apart from this we refute Drummond's claims about our alleged use of field redefinitions as well as his criticism of our dropping R^{-4} terms in our analysis. We reject his contention that our work is merely a partial reconstruction of his original results and that our work contains technical and conceptual errors. We do acknowledge the importance of the absence of terms pointed out by Drummond.

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 link is present. The argument in 0707.2179 is, among other things, specifically constructed so that the inequality in question is invoked {\it only} at strong coupling, where it is easily proven. Underlying the mangling of the argument in 0707.2179 by Ito and Seiler are their incorrect statements concerning the dependence of the potential-moving decimation procedures used in 0707.2179 on space-time dimensionality and other decimation parameters.
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.

Researchers working in lattice field theory constitute an established community since the early 1990s, and around the same time the online open-access e-print repository arXiv was created. The fact that this field has a specific arXiv section, hep-lat, which is comprehensively used, provides a unique opportunity for a statistical study of its evolution over the last three decades. We present data for the number of entries, $E$, published papers, $P$, and citations, $C$, in total and separated by nations. We compare them to six other arXiv sections (hep-ph, hep-th, gr-qc, nucl-th, quant-ph, cond-mat) and to two socio-economic indices of the nations involved: the Gross Domestic Product (GDP) and the Education Index (EI). We present rankings, which are based either on the Hirsch Index H, or on the linear combination $Ξ£= E + P + 0.05 C$. We consider both extensive and intensive national statistics, i.e. absolute and relative to the population or to the GDP.
