Second order theory of single high spins as Lorentz tensors
E. G. Delgado-Acosta, M. Kirchbach
We show that higher order differential equations and matrix spinor calculus are completely avoidable in the description of pure high spin- Weinberg-Joos states, $(j,0)\oplus (0,…
Status of the lower spins in the Rarita-Schwinger four-vector spinor within the method of the combined Lorentz- and Poincaré invariant projectors
E. G. Delgado-Acosta, V. M. Banda-Guzmán, M. Kirchbach
We investigate the status of the lower spin-1/2 companions to spin-3/2 within the four-vector spinor, . According to its reducibility, $ψ_μ\longrightarrow \left[(1/2,1)\oplus…
Electromagnetic multipole moments of elementary spin-1/2, 1, and 3/2 particles
E. G. Delgado-Acosta, M. Kirchbach, M. Napsuciale +1
We study multipole decompositions of the electromagnetic currents of spin-1/2, 1, and 3/2 particles described in terms of Lagrangians designed to reproduce representation specific…
Second order formalism for spin 1/2 fermions and Compton scattering
E. G. Delgado-Acosta, Mauro Napsuciale, Simon Rodriguez
We develop a second order formalism for spin 1/2 fermions based on the projection over Poincaré invariant subspaces in the representation of the homogeneous…
Electromagnetic couplings of elementary vector particles
M. Napsuciale, S. Rodriguez, E. G. Delgado-Acosta +1
On the basis of the three fundamental principles of (i) Poincaré symmetry of space time, (ii) electromagnetic gauge symmetry, and (iii) unitarity, we construct an universal Lagrang…
