Twistor string as tensionless superstring
Igor A. Bandos, Jose A. de Azcarraga, Cesar Miquel-Espanya
We give a brief review of the twistor string approach to supersymmetric Yang-Mills theories with an emphasis on the different formulations of (super)string models in supertwistor s…
Massive Particle Model with Spin from a Hybrid (spacetime-twistorial) Phase Space Geometry and Its Quantization
Sergey Fedoruk, Andrzej Frydryszak, Jerzy Lukierski +1
We extend the Shirafuji model for massless particles with primary spacetime coordinates and composite four-momenta to a model for massive particles with spin and electric charge. T…
Superspace formulations of the (super)twistor string
Igor A. Bandos, Jose A. de Azcarraga, Cesar Miquel-Espanya
The superspace formulation of the worldvolume action of twistor string models is considered. It is shown that for the Berkovits-Siegel closed twistor string such a formulation is p…
Extension of the Shirafuji model for Massive Particles with Spin
S. Fedoruk, A. Frydryszak, J. Lukierski +1
We extend the Shirafuji model for massless particles with primary spacetime coordinates and composite four-momenta to a model for massive particles with spin and electric charge. T…
Massive relativistic particle model with spin from free two-twistor dynamics and its quantization
Jose A. de Azcarraga, Andrzej Frydryszak, Jerzy Lukierski +1
We consider a relativistic particle model in an enlarged relativistic phase space M^{18} = (X_μ, P_μ, η_α, \oeta_\dalpha, σ_α, \osigma_\dalpha, e, ϕ), which is derived from the fre…
Two-Twistor Space, Commuting Composite Minkowski Coordinates and Particle Dynamics
A. Bette, J. Lukierski, C. Miquel-Espanya
We employ the modification of the basic Penrose formula in twistor theory, which allows to introduce commuting composite space-time coordinates. It appears that in the course of su…
