Worldline Higher Spin Gravity
Minkyeu Cho, Euihun Joung, Taehwan Oh +1
We propose a worldline formulation of higher-spin gravity (HSG) in , based on a simple twistor action. Taken at face value, the model describes only the free propag…
Ab Initio Construction of Poincaré and AdS Particle
TaeHwan Oh
We study the construction of a manifestly covariant worldline action from a coadjoint orbit. A coadjoint orbit is a submanifold in the dual vector space of a Lie algebra, generated…
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…
Manifestly Covariant Worldline Actions from Coadjoint Orbits. Part II: Twistorial Descriptions
Euihun Joung, TaeHwan Oh
Worldline actions for various twistor particles in AdS spacetimes are constructed from the coadjoint orbits of , and as constrained Hamiltonian…
