Title: LongN= 2, 4 multiplets in supersymmetric mechanics
Abstract:We define SU(2|1) supermultiplets described by chiral superfields having non-zero external spins with respect to SU(2) ⊂ SU(2|1) and show that their splitting into N = 2, d = 1 multiplets contains the...We define SU(2|1) supermultiplets described by chiral superfields having non-zero external spins with respect to SU(2) ⊂ SU(2|1) and show that their splitting into N = 2, d = 1 multiplets contains the so called "long" indecomposable N = 2, d = 1 multiplets (2, 4, 2)l. We give superfield formulation for this type of N = 2 long multiplets and construct their most general superfield action. A simple example of long N = 4, d = 1 multiplet is also considered, both in the superfield and the component formulations.Read More
