Professor Clavelli is currently interested in supersymmetry (susy),
a theory proposing that, for each particle that exists
in nature, there is a partner particle that differs only by an angular
momentum 1/2 unit of Planck's constant above or below that of the original
particle.
Many theorists believe that, due to supersymmetry, at some super-high
energy (near 1016 GeV) the nuclear, electromagnetic, and weak
forces have the same strength and fit together in a simple group-theoretic
structure. Dr. Clavelli's work explores indications from current experiments
that this is in fact the case and attempts to elicit predictions from the
theory for experiments at high energy accelerators around the world
and for observations in astroparticle physics. Most recently he has
proposed that a susy bubble
could form in dense stars which would then
expand to convert the entire star to a supersymmetric state
before cooling and collapsing into a susy black hole. Ultimately
the entire
universe would be expected to convert to a
supersymmetric state . If the
higgs structure is favorable ,
susy atoms and molecules may form.
Professor Clavelli received his bachelor degree from Georgetown University
and his doctoral degree from the University of Chicago. Since then he
has been employed in teaching and research at a number of universities and
national laboratories including Yale, Rutgers, Bordeaux, Bonn, and
Fermilab. The co-editor of two books on string theory and author of some
130 articles and conference reports in elementary particle theory,
Dr. Clavelli joined the faculty at The University of Alabama in 1985.
