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…

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…

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…
