Field Current Identities and Algebra of Fields / Lee, T D (Columbia U.) ; Zumino, B (New York U. ; CERN)
It is shown that the possible identity between the various hadronic current operators and the corresponding spin-1 meson field operators determines the general structure of the hadronic part of the total Lagrangian. In particular, the identity between the isovector electromagnetic current and the neutral ρ-meson field implies that the ρ dependence of the strong interaction must be the same as that in the Yang-Mills theory, except for the mass term of the ρ meson.

Three lectures on electric-magnetic duality / Aschieri, Paolo (Enrico Fermi Ctr., Rome ; Piemonte Orientale U., Alessandria ; INFN, Turin) ; Ferrara, Sergio (CERN ; Frascati ; UCLA) ; Zumino, Bruno (UCLA ; LBL, Berkeley)
Duality rotations in nonlinear electromagnetism are presented and basic examples reviewed. We then describe the nontrivi al example of Born-Infeld theory with n abelian gauge fields and with Sp (2 n, R ) self-duality [...]

Jordan Pairs, E6 and U-Duality in Five Dimensions / Ferrara, Sergio (CERN ; Frascati) ; Marrani, Alessio (CERN) ; Zumino, Bruno (UC, Berkeley ; LBL, Berkeley)
By exploiting the Jordan pair structure of U-duality Lie algebras in D = 3 and the relation to the super-Ehlers symmetry in D = 5, we elucidate the massless multiplet structure of the spectrum of a broad class of D = 5 supergravity theories. Both simple and semi-simple, Euclidean rank-3 Jordan algebras are considered. [...]

Freudenthal Gauge Theory / Marrani, Alessio (CERN) ; Qiu, Cong-Xin (Minnesota U.) ; Shih, Sheng-Yu Darren (UC, Berkeley) ; Tagliaferro, Anthony (UC, Berkeley) ; Zumino, Bruno (UC, Berkeley ; LBL, Berkeley)
We present a novel gauge field theory, based on the Freudenthal Triple System (FTS), a ternary algebra with mixed symmetry (not completely symmetric) structure constants. The theory, named Freudenthal Gauge Theory (FGT), is invariant under two (off-shell) symmetries: the gauge Lie algebra constructed from the FTS triple product and a novel global non-polynomial symmetry, the so-called Freudenthal duality. [...]

Charge Orbits of Extremal Black Holes in Five Dimensional Supergravity / Cerchiai, Bianca L (Milan U.) ; Ferrara, Sergio (CERN) ; Marrani, Alessio (Stanford U.) ; Zumino, Bruno (LBL, Berkeley ; UC, Berkeley)
We derive the U-duality charge orbits, as well as the related moduli spaces, of "large" and "small" extremal black holes in non-maximal ungauged Maxwell-Einstein supergravities with symmetric scalar manifolds in d=5 space-time dimensions. The stabilizer groups of the various classes of orbits are obtained by determining and solving suitable U-invariant sets of constraints, both in "bare" and "dressed" charges bases, with various methods.

Duality, Entropy and ADM Mass in Supergravity / Cerchiai, Bianca L. (LBL, Berkeley ; UC, Berkeley) ; Ferrara, Sergio (CERN ; Frascati) ; Marrani, Alessio (Stanford U., ITP ; UC, Berkeley) ; Zumino, Bruno (LBL, Berkeley ; UC, Berkeley)
We consider the Bekenstein-Hawking entropy-area formula in four dimensional extended ungauged supergravity and its electric-magnetic duality property. Symmetries of both "large" and "small" extremal black holes are considered, as well as the ADM mass formula for N=4 and N=8 supergravity, preserving different fraction of supersymmetry. [...]

We review the general theory of duality rotations which, in four dimensions, exchange electric with magnetic fields. Necessary and sufficient conditions in order for a theory to have duality symmetry are established. [...]
