'Glueballs' are hypothetical nuclear
particles that have eluded
researchers for decades. If at all they
exist, they are too short-lived to be
observed directly. Now, after
solving one million trillion arithmetic problems by running many
computers for over two years,
scientists at IBM claim to have
demonstrated the existence of these
elusive particles.
IBM scientists say that the
numbers produced by their computers match the numbers derived
from certain nuclear collisions in
particle accelerators over the years.
Researchers say their discovery is
expected to bolster a widely
accepted theory called quantum
chromodynamics or QCD -part of
a theory in particle physics known
as Standard Model, that accounts
for the strong nuclear force.
