Spinor-helicity formalism for continuous-spin particles
Thomas Basile, Xavier Bekaert, Felipe Figueroa +1
We propose a new formulation of continuous-spin particles (CSP) with the help of a single two-component spinor to build asymptotic states. This formulation allows to write down amp…
Multisymplectic AKSZ sigma models
Thomas Basile, Maxim Grigoriev, Evgeny Skvortsov
The Alexandrov-Kontsevich-Schwarz-Zaboronsky (AKSZ) construction encodes all the data of a topological sigma-model in the finite-dimensional symplectic -manifold. Relaxing the n…
Spinor-helicity representations of (A)dS particles of any mass
Thomas Basile, Euihun Joung, Karapet Mkrtchyan +1
The spinor-helicity representations of massive and (partially-)massless particles in four dimensional (Anti-) de Sitter spacetime are studied within the framework of the dual pair…
Manifestly Covariant Worldline Actions from Coadjoint Orbits. Part I: Generalities and Vectorial Descriptions
Thomas Basile, Euihun Joung, TaeHwan Oh
We derive manifestly covariant actions of spinning particles starting from coadjoint orbits of isometry groups, by using Hamiltonian reductions. We show that the defining condition…
Chiral approach to partially-massless fields
Thomas Basile, Shailesh Dhasmana, Evgeny Skvortsov
We propose a new (chiral) description of partially-massless fields in , including the partially-massless graviton, that is similar to the pure connection formulation for gravit…
Covariant action for conformal higher spin gravity
Thomas Basile, Maxim Grigoriev, Evgeny Skvortsov
Conformal Higher Spin Gravity is a higher spin extension of Weyl gravity and is a family of local higher spin theories, which was put forward by Segal and Tseytlin. We propose a ma…
