Nonanomalous DiscreteRSymmetry Decrees Three Generations

Nonanomalous discrete R symmetry decrees three generations.

We show that more than two generations of quarks and leptons are required to have an anomaly free discrete R symmetry larger than R parity, provided that the supersymmetric standard model can be minimally embedded into a grand unified theory. This connects an explanation for the number of generations with seemingly unrelated problems such as supersymmetry breaking, proton decay, the μ problem, ...

Three Generations

as my father and grandfather were also members of our great profession I thought I would try and look at life as it was since 1846 when my grandfather obtained his qualificationi of L.R.C.S. in Edinibuirgh, inci(denltally he was Presi(lent of this Society in 187576.

Buphthalmos over Three Generations.

Case Reports Case 1, a female child (IV, 3 in Pedigree) born on December 23, 1958, was noticed to have opaque corneae, of sufficient degree to prevent any estimate of the size of the pupils. There was corneal oedema but no appreciable abnormality of the corneal diameter. In the course of a few days the cornea of each eye had become obviously enlarged and a definite buphthalmos had become establ...
