Persistent Challenges of Quantum Chromodynamics

M. Shifman

Unlike some models whose relevance to Nature is still a big question mark, Quantum Chromodynamics will stay with us forever. Quantum Chromodynamics (QCD), born in 1973, is a very r…

Central Charge Anomalies in 2D Sigma Models with Twisted Mass

M. Shifman, A. Vainshtein, R. Zwicky

We discuss the central charge in supersymmetric $N = 2$ sigma models in two dimensions. The target space is a symmetric Kähler manifold, CP $(N - 1)$ is an example. The U(1) isom…
