(A)dS exchanges and partially-massless higher spins
D. Francia, J. Mourad, A. Sagnotti
We determine the current exchange amplitudes for free totally symmetric tensor fields $\vf_{μ_1 ... μ_s}$ of mass in a -dimensional space, extending the results previou…
On Higher Spins with a Strong Sp(2,R) Condition
A. Sagnotti, E. Sezgin, P. Sundell
We report on an analysis of the Vasiliev construction for minimal bosonic higher-spin master fields with oscillators that are vectors of SO(D-1,2) and doublets of Sp(2,R). We show…
An Introduction to Free Higher-Spin Fields
N. Bouatta, G. Compere, A. Sagnotti
In this article we begin by reviewing the (Fang-)Fronsdal construction and the non-local geometric equations with unconstrained gauge fields and parameters built by Francia and the…
Open strings and their symmetry groups
Augusto Sagnotti
Much of the recent progress in String Theory can be traced to a precise strategy: a careful study of the few models known since the beginnings of the subject, and the abstraction f…
Type-I vacua and brane transmutation
C. Angelantonj, A. Sagnotti
In a classic paper, Fradkin and Tseytlin showed how magnetic deformations can be introduced in open strings. In this contribution we review some recent work on type-I vacua with ma…
Self-dual Tensors in Six-Dimensional Supergravity
Fabio Riccioni, Augusto Sagnotti
We review some properties of the field equations of six-dimensional (1,0) supergravity coupled to tensor and vector multiplets, and in particular their relation to covariant and co…
