Summary:
Professor
Taylor's main research areas are superstring theory and
in general, supersymmetric theories of fundamental interactions.
In supersymmetric theories, half-integer spin particles,
like quarks and leptons, are accompanied by spin zero
particles with identical masses and charges. The advantage
of supersymmetry is that it provides a natural framework
for the existence of the Higgs particle which is responsible
for electroweak symmetry breaking in the standard model
of elementary particles. Moreover, quantum field theories
based on local supersymmetry automatically incorporate
gravity together with electroweak and strong forces. These
supergravity theories suffer, though, from some internal
inconsistencies related to their peculiar short-distance
behaviour.
Superstring theory provides us with the only known consistent
framework for unifying all forces. Elementary particles
appear as quantized oscillations of very small strings.
The short-distance behaviour is different here from standard
field theories because fundamental objects are not point-like
particles but extended strings. At large distances, elementary
particle interactions are described by an effective supergravity
theory. Supersymmetry must be broken, however, in order
to explain why spin zero quarks and leptons have not been
observed yet in high energy laboratories.
The most exciting thing about superstring theory is that
all physical parameters, like the electron and proton
masses, fine structure constant, etc., can be determined
from first principles. Professor Taylor's research is
focussed on the computations of physical quantities like
couplings and masses and in general, on the large-distance,
macroscopic behaviour of superstring theory. He has also
a long research record on the problem of supersymmetry
breaking.
