A note about a pure spin-connection formulation of General Relativity and spin-2 duality in (A)dS
Thomas Basile, Xavier Bekaert, Nicolas Boulanger
We investigate the problem of finding a pure spin-connection formulation of General Relativity with non-vanishing cosmological constant. We first revisit the problem at the lineari…
Quartic AdS Interactions in Higher-Spin Gravity from Conformal Field Theory
Xavier Bekaert, Johanna Erdmenger, Dmitry Ponomarev +1
Clarifying the locality properties of higher-spin gravity is a pressing task, but notoriously difficult due to the absence of a weakly-coupled flat regime. The simplest non-trivial…
A gauge field theory of fermionic Continuous-Spin Particles
X. Bekaert, M. Najafizadeh, M. R. Setare
In this letter, we suggest a local covariant action for a gauge field theory of fermionic Continuous-Spin Particles (CSPs). The action is invariant under gauge transformations with…
Notes on conformal invariance of gauge fields
Glenn Barnich, Xavier Bekaert, Maxim Grigoriev
In Lagrangian gauge systems, the vector space of global reducibility parameters forms a module under the Lie algebra of symmetries of the action. Since the classification of global…
Connections and dynamical trajectories in generalised Newton-Cartan gravity II. An ambient perspective
Xavier Bekaert, Kevin Morand
Connections compatible with degenerate metric structures are known to possess peculiar features: on the one hand, the compatibility conditions involve restrictions on the torsion;…
Mixed-symmetry multiplets and higher-spin curvatures
Xavier Bekaert, Nicolas Boulanger, Dario Francia
We study the higher-derivative equations for gauge potentials of arbitrary mixed-symmetry type obtained by setting to zero the divergences of the corresponding curvature tensors. W…
