"Eckhard D. Falkenberg, who found evidence of an annual oscillation in the beta-decay rate of tritium, was either the first or one of the first to propose that some beta-decay rates may be variable. He suggested that the beta-decay process may be influenced by neutrinos, and attributed the annual variation to the varying Earth-Sun distance that leads to a corresponding variation in the flux of solar neutrinos as detected on Earth. Supporting evidence for the variability of beta-decay rates could be found in the results of an experiment carried out at the Brookhaven National Laboratory."

High Energy Physics: 5 Needed Breakthroughs
-- Pierre Ramond

[ Prof. Pierre Ramond, Distinguished Professor of Physics at University of Florida in Gainesville, is today's guest in our ongoing feature '5-Breakthroughs'.

During his long career starting with the PhD work at Syracuse University in 1969, Prof. Ramond contributed in some significant developments in the study of elementary particles and fields. Notable among those is the crucial role he played in the early development of superstring theory.

Early string theory proposed by Yoichiro Nambu and others in 1970 was based on bosonic string. At that point, Pierre Ramond took the crucial step of generalizing the Virasoro algebra, the symmetry algebra of the bosonic string, to a superconformal algebra including anticommuting operators. The inclusion of a fermionic string to accompany the bosonic ones completed the theory of strings. In 1971, he generalized Dirac's equation for point-like particles to string-like ones, which laid a solid foundation for the superstring theory. A comprehensive list of the variety of work he did can be found in Google Scholar link.

Prof. Ramond is a Fellow of American Physical Society and American Academy of Arts & Sciences. In August 2004, he was awarded Oskar Klein Medal by Swedish Royal Academy of Sciences and Stockholm University.

Many of us grew up with his celebrated book "Field Theory: A Modern Primer" (Addison / Wesley, 1981) and also experienced the pleasure of "Journeys Beyond the Standard Model"(Perseus, 1999), his other book. It's thus our pleasure to present the 5 most important breakthroughs that Prof. Ramond would like to see in High Energy Physics.

Here is my list of five:

Finding Supersymmetry with the Large Hadronic Collider, and if found, understanding Supersymmetry breaking.

Understanding why there are three chiral families of Elementary Particles (closely related to finding the organizing principle behind chiral symmetry breaking, e.g. Yukawa interactions).

Observation of Proton Decay in the Laboratory.

Determining the Character (Majorana or Dirac) of Neutrino masses.

Identifying Dark Matter.
