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…
Compton scattering off massive fundamental bosons of pure spin 1
E. G. Delgado-Acosta, M. Kirchbach, M. Napsuciale +1
Relativistic particles with spins are described by means of multicomponent wave functions which transform covariantly according to Lorentz-group representations that contain…
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…
Compton scattering off elementary spin 3/2 particles
E. G. Delgado-Acosta, M. Napsuciale
We calculate Compton scattering off an elementary spin 3/2 particle in a recently proposed framework for the description of elementary high spin fields based on the projection onto…
