STRING theoryMODEL theoryGRAVITYQUANTUM groupsIn a previous article we proposed a new model for quantum gravity (QGR) and cosmology, dubbed S U (∞) -QGR. One of the axioms of this model is that Hilbert spaces of the Universe and its subsystems represent the S U (∞) sym...

In any case, even if one regards the measure as an extra divergence in the 4d theory compared to the 2d one, the link between the 4d and 2d RG flows is only minimally modified and statements such as renormalisability unaffected. We believe this to be the first quantum check of the 4d...

The latter are quantum field theories formulated in a string-like manner, and they inherit with some modifications the structures of ordinary string theory that so naturally express the double copy; refs. [72–76] study the precise connection to string theory. Crucially, ambitwistor strings ...
1. Introduction The approaches to one of the most important problems in physics, namely the quantum gravity (QG) conundrum, have evolved a lot since the last two decades. The most known contender having some undeniable results is certainly String Theory [1] whereas alternative approaches1 like ...
It has been known for a long time that there are no virtual collinear divergences in any quantum theory of gravitation [88]. Furthermore, it can be shown that the structure of the soft divergences in gravity is completely controlled by the one-loop result, which contains a 1/ pole. ...
The low-energy expansion of string amplitudes exposed by such recursions at tree and loop level contains a wealth of information on relations between gauge theories and gravity, string dualities and counterterms including their non- renormalization theorems. For the moduli-space integrals in open-...
