Paul Frampton
From Wikipedia, the free encyclopedia
Paul Frampton (born October 31, 1943 in England) is a theoretical physicist, active in the field of phenomenological model building in cosmology and high energy physics. He is the Louis D. Rubin, Jr. [1] Professor of Physics at the University of North Carolina at Chapel Hill. He received a BA (1965, double first), MA DPhil (1968) and DSc (1984) from the University of Oxford where he is a former student of Brasenose College.

[edit] Research
His cosmology papers include a cyclic model (2007) [2] for the universe which uses phantom energy to solve its entropy problem and requires an equation of state for dark energy which could be verified by the Planck Surveyor satellite to be launched in 2008. He was the author of the first ever book on string theory in 1974 [3] when it was still known by the name dual resonance models and followed that with a 1986 monograph [4] on gauge field theories. In quantum field theory he provided in 1976 the first correct calculation for vacuum decay [5] then in 1983 participated in the earliest calculation [6] of a chiral anomaly pertinent to ten dimensional string theory.
He studies model building in particle theory to find testable extensions of the Standard Model. Two examples are the Chiral Color model (1987, with Sheldon Glashow) [7] [8] and the 331 model (1992) [9]. Chiral color predicts a color octet of spin one electrically neutral axigluons coupled to quarks and the 331 model, which requires three fermion families, predicts a spin one bilepton which can have electric charge -2e and couple to two electrons. One of these particles could be discovered at the Large Hadron Collider expected to start collecting data in 2008. Since the experimental establishment of neutrino oscillations in 1998 he has contributed (1999, 2002 with Sheldon Glashow) [10] [11] [12] papers about neutrino masses and mixings.
