Pseudoclassical mechanics for the spin-0 and -1 particles
Sifuentes, Rodolfo Alvan Casana; Pazetti, Márcio; Escobar, Bruto Max Pimentel; Salvador, Juan Segundo Valverde (2009)We give an action for the massless spinning particle in pseudoclassical mechanics by using grassmann variables. The constructed action is invariant under _-reparametrizations, local SUSY and O(N) transformations. After ... -
Relativstic particle dynamics in D=2+1
Valverde, Juan Segundo; Pazetti, Márcio (2006)We propose a SUSY variant of the action for a massless spinning particles via the inclusion of twistor variables. The action is constructed to be invariant under SUSY transformations and -reparametrizations even when an ...
