A theory for multiple partially massless spin-2 fields
Nicolas Boulanger, Cédric Deffayet, Sebastian Garcia-Saenz +1
We revisit the problem of building consistent interactions for a multiplet of partially massless spin-2 fields in (anti-)de Sitter space. After rederiving and strengthening the exi…
Consistent deformations of free massive field theories in the Stueckelberg formulation
Nicolas Boulanger, Cédric Deffayet, Sebastian Garcia-Saenz +1
Cohomological techniques within the Batalin-Vilkovisky (BV) extension of the Becchi-Rouet-Stora-Tyutin (BRST) formalism have proved invaluable for classifying consistent deformatio…
Spin-2 twisted duality in (A)dS
Nicolas Boulanger, Andrea Campoleoni, Ignacio Cortese +1
Starting from the dual Lagrangians recently obtained for (partially) massless spin-2 fields in the Stueckelberg formulation, we write the equations of motion for (partially) massle…
Uniqueness of and pure supergravities in 4D
Nicolas Boulanger, Bernard Julia, Lucas Traina
After proving the impossibility of consistent non-minimal coupling of a real Rarita-Schwinger gauge field to electromagnetism, we re-derive the necessity of introducing the gravito…
