Two-component spinors are the basic ingredients for describing fermions in quantum field
theory in 3+ 1 spacetime dimensions. We develop and review the techniques of the two …

We review a geometrical approach to the description of the dynamics of superparticles,
superstrings and, in general, of super-p-branes, Dirichlet branes and the M5-brane, which is …

I provide a pedagogical introduction to supersymmetry. The level of discussion is aimed at
readers who are familiar with the Standard Model and quantum field theory, but who have …

I provide a pedagogical introduction to supersymmetry. The level of discussion is aimed at

An exact and general solution is presented for a previously open problem. We show that the
superconformal R-symmetry of any 4d SCFT is exactly and uniquely determined by a …

We argue that all scattering amplitudes in the maximally supersymmetric N= 4 super-Yang–
Mills theory possess a new, dual superconformal symmetry which extends the previously …

This is a pedagogical introduction to the harmonic superspace method in extended
supersymmetry. Inspired by exciting developments in superstring theory, it provides a …

A bstract We give a prescription for\(\mathcal {N}\)= 1 supersymmetrization of any (four-
dimensional) nonlinear electrodynamics theory with a Lagrangian density satisfying a …

For quantum field theories that flow between ultraviolet and infrared fixed points, central
functions, defined from two-point correlators of the stress tensor and conserved currents …

I present a pedagogical review of Heisenberg–Euler effective Lagrangians, beginning with
the original work of Heisenberg and Euler, and Weisskopf, for the one loop effective action of …
