Mass splitting in spin-unitary spin higher symmetry schemes

Nuclear Physics, 1966
Abstract A method of allowing mass splitting in U (12) or U (8) multiplets is suggested. Instead of breaking these groups by requiring the invariance of generalized Bargmann-Wigner equations, we break the symmetry by first decomposing the representations with respect to the U (3) × S p (4) or U (2) × S p (4 ...

Consequences ofU-spin for several higher symmetries

Il Nuovo Cimento, 1964
TheU-spin is defined for the higher-symmetry models based on theG2 andC2 algebras. Some relations concerning the masses and electromagnetic properties of the particles are derived and compared with the experimental situation. TheG2 model is found to be in contradiction with experiment especially for electromagnetic processes.

Matrix representation of higher integer conformal spin symmetries

Journal of Mathematical Physics, 1995
Using infinite matrices, we construct the generating functional of higher integer conformal spin extensions of the Virasoro algebra and the SU(2) spin 1/2 representation loop algebra. Higher conformal spin symmetries are realized on the set F1/2 of the configurations of the homogeneous Ising chain. This is an infinite-dimensional vector space reducible

Higher-spin symmetries of the massless (super)particle

Classical and Quantum Gravity, 1991
The full symmetry group of the free massless (super)particle is studied, for spacetime dimensions \(d=2\), 3, 4 and 6, using (super)twistor methods. The corresponding infinite-rank algebra contains an infinite sum of irreducible representations of the conformal group.

Aspects of higher spin symmetry in flat space

La Rivista del Nuovo Cimento
International audience ; We review some aspects of higher spin symmetry, in (Anti-)de Sitter and flat space–times, aiming at closing the gap between the constantly curved and flat cases. On (Anti-)de Sitter space, non-Abelian higher spin algebras are at the core of the construction of interacting theories of higher spin gravity.
