Using the techniques of finite-temperature field theory we renormalize the electromagnetic and gravitational couplings of an electron which is immersed in a heat bath with T

Possibilities For Finite Grand Unification With N = 2 Supersymmetry, Asim Gangopadhyaya Dec 1983

Possibilities For Finite Grand Unification With N = 2 Supersymmetry, Asim Gangopadhyaya

Asim Gangopadhyaya

We study the prospects for constructing finite grand unified theories using softly broken N = 2 global supersymmetry. The requirement that the supersymmetry breaking scale be of order 103−104 GeV and that the mixing between the observed light fermions and the mirror fermions present in N = 2 theories be small («mW), make it difficult to construct finite grand unified theories based on a large class of simple groups with a realistic symmetry breaking pattern.

Predicting The Proton Mass From Pi-Pi-Scattering Data, Jf Donoghue, E Golowich, Br Holstein

Barry R Holstein

We relate experimental information on ππ scattering to tree-level effective chiral Lagrangians. The result is of a form similar to that used in Skyrme-type models of the proton, where the nucleons are described as topologically stable solitons of the chiral fields. In such models, one can express the proton mass in terms of measured scattering data, with the result Mp=880±300 MeV. We interpret this as a consistency test for the Skyrme models.
