Query: Long N=2, 4 multiplets in supersymmetric mechanics   We define SU(2|1) supermultiplets described by chiral superfields having
non-zero external spins with respect to SU(2) \subset 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.
