Massimo Taronna - Scuola Normale Superiore - Higher-Spin Interactions: three-point functions and beyond

Tue, Nov 1, 2011, 1:00 pm to 2:30 pm
PCTS Seminar Room
Taking String Theory as a ``theoretical laboratory'', I will present handy expressions for bosonic and fermionic (SUSY) higher-spin Noether currents. I will also describe a class of non-local higher-spin Lagrangian couplings that are generically required by the Noether procedure starting from four-points. The construction clarifies the origin of old problems for these systems and links String Theory to some aspects of Field Theory that go beyond its conventional low energy limit. I will finally discuss how the extension of these results to (A)dS brings about the emergence of minimal-like couplings from higher-derivative ones.
