[net.physics] Z0 & W Bosons

The Z0 and the W intermediate vector bosons have been discovered at
CERN.  (There were something like 128 collaborators from many
countries -- everyone was looking for these particles!)  It is thought
that they act as the intermediary in weak (radioactive decay)
interactions as photons do for electromagnetics interactions.  The
mass of each of the two particles is greater than 80 times that of the
proton.
The New York Times(May 29, 1983) in an article by Heinz Pagels says,
"By the late 1960's, Dr. Steven Weinberg... and Dr. Salam at Imperial
College, London, devised a field theory that unified the weak and
electromagnetic forces.  At the heart of their theory, which was based
on the earlier work of scientists including Dr. Sheldon Glashow, also
at Harvard, was the idea that the weak and electromagnetic fields were
unified by a symmetry transformation... The weak and electromagnetic
fields could be interchanged because of the mathematical symmetry of
the Weinberg-Salam theory."
	Even tho the math is symmetric the solutions to the
equations, which describes the forces and particles, needn't be.
Hope this tells you a little of what's going on.  I also find it
fascinating, but reliable news isn't always so easy to get.  It's not
clear that the New York Times writers understand the significance of
scientific events all that well...
