  New developments in 2T-physics, that connect 2T-physics field theory directly
to the real world, are reported in this talk. An action is proposed in field
theory in 4+2 dimensions which correctly reproduces the Standard Model (SM) in
3+1 dimensions (and no junk). Everything that is known to work in the SM still
works in the emergent 3+1 theory, but some of the problems of the SM get
resolved. The resolution is due to new restrictions on interactions inherited
from 4+2 dimensions that lead to some interesting physics and new points of
view not discussed before in 3+1 dimensions. In particular the strong CP
violation problem is resolved without an axion, and the electro-weak symmetry
breakdown that generates masses requires the participation of the dilaton, thus
relating the electro-weak phase transition to other phase transitions (such as
evolution of the universe, vacuum selection in string theory, etc.) that also
require the participation of the dilaton. The underlying principle of
2T-physics is the local symmetry Sp(2,R) under which position and momentum
become indistinguishable at any instant. This principle inevitably leads to
deep consequences, one of which is the two-time structure of spacetime in which
ordinary 1-time spacetime is embedded. The proposed action for the Standard
Model in 4+2 dimensions follows from new gauge symmetries in field theory
related to the fundamental principles of Sp(2,R). These gauge symmetries thin
out the degrees of freedom from 4+2 to 3+1 dimensions without any Kaluza-Klein
modes.
