The OSp(1|4) Superparticle and Exotic BPS States
Igor Bandos, Jerzy Lukierski, Dmitri Sorokin
We discuss the dynamics of a superparticle in a superspace whose isometry is generated by the superalgebra OSp(1|4) or its central-charge contraction. Extra coordinates of the supe…
Generalized Superconformal Symmetries and Supertwistor Dynamics
Igor Bandos, Jerzy Lukierski, Dmitri Sorokin
We show that in the supersymmetry framework described by a Poincaré superalgebra with tensorial central charges the role of generalized superconformal symmetry which contains all t…
OSp supergroup manifolds, superparticles and supertwistors
Igor Bandos, Jerzy Lukierski, Christian Preitschopf +1
We construct simple twistor-like actions describing superparticles propagating on a coset superspace OSp(1|4)/SO(1,3) (containing the D=4 anti-de-Sitter space as a bosonic subspace…
Superparticle Models with Tensorial Central Charges
Igor Bandos, Jerzy Lukierski, Dmitri Sorokin
A generalization of the Ferber-Shirafuji formulation of superparticle mechanics is considered. The generalized model describes the dynamics of a superparticle in a superspace exten…
Distance Measurement and -Deformed Propagation of Light and Heavy Probes
Giovanni Amelino-Camelia, Jerzy Lukierski, Anatol Nowicki
We investigate the implications for the measurability of distances of a covariant dimensionful ``'' deformation of D=4 relativistic symmetries, with quantum time coordinate and…
