The / e π ν π μν → → branching ratio provides unique access to physics beyond the Standard Model due to the extraordinary precision of its SM prediction and the potential for highly accurate measurements. The motivation and prospects for new measurements presently underway at PSI and TRIUMF will be discussed.

poly(vinyl acetate) is synthesized via solution polymerization, and then it is converted to poly(vinyl alcohol) by alkaline alcoholysis. the aim of the work study was to investigate statistically the  influence of reaction variables in vinyl acetate polymerization, the conversion of this monomer to polymer, degree of branching of acetyl group in poly(vinyl acetate), as well as the molecular wei...
