Nonperturbative Effects and the Large–Order Behavior of Matrix Models and Topological Strings
This work addresses nonperturbative effects in both matrix models and topological strings, and their relation with the large–order behavior of the 1/N expansion. We study instanton configurations in generic one–cut matrix models, obtaining explicit results for the one–instanton amplitude at both one and two loops. The holographic description of topological strings in terms of matrix models impl...
متن کاملLarge–order behavior of non–decoupling effects and triviality
We compute some non–decoupling effects in the standard model, such as the ρ parameter, to all orders in the coupling constant expansion. We analyze their large order behavior and explicitly show how it is related to the non–perturbative cutoff dependence of these non–decoupling effects due to the triviality of the theory. 9/93 † email: [email protected]
متن کاملNormalization Constants of Large Order Behavior
A perturbation scheme is discussed for the computation of the normalization constant of the large order behavior arising from an ultraviolet renormalon. In this scheme the normalization constant is expressed in a convergent series that can be calculated using the ordinary perturbative expansion and the nature of the renormalon singularity.

متن کاملNonperturbative effects on nucleation.
A nonperturbative correction to the thermal nucleation rate of critical bubbles in a first-order phase transition is estimated. Using a simple model of a scalar field in a double-well potential, we obtain a corrected potential which incorporates the free-energy density available from large-amplitude fluctuations, which is not included in the usual perturbative calculation. As an application of ...
متن کاملNonperturbative QCD Effects in Weak
QCD-based analysis of nonfactorizable parts of weak nonleptonic amplitudes is reported. Nonperturbative effects due to soft gluon exchange play a key role leading to the emergence of a dynamical rule of discarding 1/N c corrections.
