Gravity Cutoff in Theories with Large Discrete Symmetries
Gia Dvali, Michele Redi, Sergey Sibiryakov +1
We set an upper bound on the gravitational cutoff in theories with exact quantum numbers of large N periodicity, such as Z_N discrete symmetries. The bound stems from black hole ph…

Central Charge Anomalies in 2D Sigma Models with Twisted Mass
M. Shifman, A. Vainshtein, R. Zwicky
We discuss the central charge in supersymmetric sigma models in two dimensions. The target space is a symmetric Kähler manifold, CP is an example. The U(1) isom…

Instantons Versus Supersymmetry: Fifteen Years Later
Mikhail Shifman, Arkady Vainshtein
An introduction to the instanton formalism in supersymmetric gauge theories is given. We explain how the instanton calculations, in conjunction with analyticity in chiral parameter…
