Research Interests
My current interests include String Field Theory
(SFT), and Two-Time
Physics (2T-Physics). My long term goal is the construction of the unified
M-theory at the fundamental level. In 2006 I have established that all the
physics we know today, as embodied in principle in the Standard Model of
Particles and Forces, is described by a gauge fixed version of 2T-physics in 4
space and 2 time dimensions.
My research is driven by some
of the current questions in Cosmology, the Standard Model of elementary
particles, and unification of forces including quantum gravity. The mysteries
that are hoped to be resolved include the physics of the very early universe
and how it determined the gauge symmetries (forces) and the families of quarks
and leptons (matter) that we observe today. Once the fundamental theory is
constructed it is likely that it will suggest the best approach to answer our
current questions.
I emphasize symmetries and supersymmetries in much of my research on particle
physics, field theory and string theory. From time to time the symmetry
structures in physics have led me to discover new physical concepts, such as
Two-Time Physics (2T-Physics), as well as a few new structures
in Mathematics or Mathematical Physics, in particular in supergroups,
non-compact groups, and noncommutative geometry. This activity also took me on
side trips into applications of symmetries in other fields of physics.
Consequently, supersymmetry
in nuclear physics was experimentally confirmed as an approximate symmetry
of bosonic and fermionic nuclei.
Some of the theoretical computations I did in the past on the Standard Model,
gauge theories, and grand unification, are currently of experimental interest.
In particular the first computation of the weak interaction contribution to the
anomalous
magnetic moment of the muon has recently been confirmed by measurments
performed more than 30 years later. I suspect that some of my past work on
"phenomenology" would be relevant for the next round of exciting
experiments at the Large Hadron Collider at CERN starting in 2008.
