Master Higher-Spin Particle
Sergey Fedoruk, Evgeny Ivanov
We propose a "master" higher-spin (HS) particle system. The particle model relevant to the unfolded formulation of HS theory, as well as the HS particle model with a bosonic counte…
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…
Uniform Twistor-Like Formulation of Massive and Massless Superparticles with Tensorial Central Charges
S. Fedoruk, V. G. Zima
We construct the manifestly Lorentz-invariant twistorial formulation of N=1 D=4 superparticle with tensorial central charges which describes massive and massless cases in a uniform…
Massive Superparticle with Tensorial Central Charges
S. Fedoruk, V. G. Zima
We construct the manifestly Lorenz-invariant formulation of the N=1 D=4 massive superparticle with tensorial central charges. The model contains a real parameter k and at …
Weinberg propagator of a free massive particle with an arbitrary spin from the BFV-BRST path integral
V. G. Zima, S. O. Fedoruk
The transition amplitude is obtained for a free massive particle of arbitrary spin by calculating the path integral in the index-spinor formulation within the BFV-BRST approach. No…
