  We construct N=1 supersymmetry in 4+2 dimensions compatible with the
theoretical framework of 2T physics field theory and its gauge symmetries. The
fields are arranged into 4+2 dimensional chiral and vector supermultiplets, and
their interactions are uniquely fixed by SUSY and 2T-physics gauge symmetries.
Many 3+1 spacetimes emerge from 4+2 by gauge fixing. Gauge degrees of freedom
are eliminated as one comes down from 4+2 to 3+1 dimensions without any
remnants of Kaluza-Klein modes. In a special gauge, the remaining physical
degrees of freedom, and their interactions, coincide with ordinary N=1
supersymmetric field theory in 3+1 dimensions. In this gauge, SUSY in 4+2 is
interpreted as superconformal symmetry SU(2,2|1) in 3+1 dimensions.
Furthermore, the underlying 4+2 structure imposes some interesting restrictions
on the emergent 3+1 SUSY field theory, which could be considered as part of the
predictions of 2T-physics. One of these is the absence of the troublesome
renormalizable CP violating F*F terms. This is good for curing the strong CP
violation problem of QCD. An additional feature is that the superpotential is
required to have no dimensionful parameters. To induce phase transitions, such
as SUSY or electro-weak symmetry breaking, a coupling to the dilaton is needed.
This suggests a common origin of phase transitions that is driven by the vacuum
value of the dilaton, and need to be understood in a cosmological scenario as
part of a unified theory that includes the coupling of supergravity to matter.
Another interesting aspect is the possibility to utilize the inherent 2T gauge
symmetry to explore dual versions of the N=1 theory in 3+1 dimensions. This is
expected to reveal non-perturbative aspects of ordinary 1T field theory.
