Is there a third-order phase transition in quenched QCD?
L. Li, Y. Meurice
We discuss the connection between the contributions of large field configurations and the large order behavior of perturbation theory. For quenched QCD, the sensitivity of the aver…
Asymptotically Universal Crossover in Perturbation Theory with a Field Cutoff
L. Li, Y. Meurice
We discuss the crossover between the small and large field cutoff (denoted x_{max}) limits of the perturbative coefficients for a simple integral and the anharmonic oscillator. We…
About a possible 3rd order phase transition at T=0 in 4D gluodynamics
L. Li, Y. Meurice
We revisit the question of the convergence of lattice perturbation theory for a pure SU(3) lattice gauge theory in 4 dimensions. Using a series for the average plaquette up to orde…
Universal Crossover in Perturbation Theory with a Large Field Cutoff
L. Li, Y. Meurice
For lambda phi^4 models, the introduction of a large field cutoff improves significantly the accuracy that can be reached with perturbative series but the calculation of the modifi…
An example of optimal field cut in lattice gauge perturbation theory
L. Li, Y. Meurice
We discuss the weak coupling expansion of a one plaquette SU(2) lattice gauge theory. We show that the conventional perturbative series for the partition function has a zero radius…
