Discovery of Supersymmetry in Nuclei
There is now experimental evidence
supersymmetry in nuclei (see citations below).
Its existence (in broken form)
was first proposed
by Hagen Kleinert (FU-Berlin) during a discussion session
after a lecture of Sergio Ferrara on
Supersymmetric Theories of Fundamental Interactions
held at the 1978 Erice School. It is
The New Aspects of Subnuclear Physics
Plenum Press, N.Y., 1980 (ed. by A. Zichichi), pp. 1--37.
The discussion sessions are reprinted on pp. 39--58.
The reprint of the first session can be downloaded below .
It documents that upon a question posed by the
Yale student Yuan K. HA (now professor at Temple University),
whether there could be supersymmetry in nuclei,
was answered affirmatively by Kleinert
who pointed out that a simple model of even and odd nuclei
exhibits broken supersymmetry.
Kleinert had previously presented auch a
model at the 1977 Erice Summer School
on Low Temperature Physics for a different purpose
[lecture is published under the title
Collective Quantum Fields,
Fortschr. Physik 26, 565-671
