A proposal for a manifestly gauge invariant and universal calculus in Yang-Mills theory
Stefano Arnone, Antonio Gatti, Tim R. Morris
We uncover a method of calculation that proceeds at every step without fixing the gauge or specifying details of the regularisation scheme. Results are obtained by iterated use of…
Towards a manifestly gauge invariant and universal calculus for Yang-Mills theory
Stefano Arnone, Antonio Gatti, Tim R. Morris
A manifestly gauge invariant exact renormalization group for pure SU(N) Yang-Mills theory is proposed, along with the necessary gauge invariant regularisation which implements the…
Manifestly gauge invariant computations
Stefano Arnone, Antonio Gatti, Tim R. Morris
Using a gauge invariant exact renormalization group, we show how to compute the effective action, and extract the physics, whilst manifestly preserving gauge invariance at each and…
A manifestly gauge invariant exact renormalization group
Stefano Arnone, Antonio Gatti, Tim R. Morris
A manifestly gauge invariant exact renormalization group for pure SU(N) Yang-Mills theory is proposed, allowing gauge invariant calculations, without any gauge fixing or ghosts. Th…
A demonstration of scheme independence in scalar ERGs
Stefano Arnone, Antonio Gatti, Tim R. Morris
The standard demand for the quantum partition function to be invariant under the renormalization group transformation results in a general class of exact renormalization group equa…
Exact scheme independence at one loop
Stefano Arnone, Antonio Gatti, Tim R. Morris
The requirement that the quantum partition function be invariant under a renormalization group transformation results in a wide class of exact renormalization group equations, diff…
