Measurements of αs in e+e- Interactions

  • R. Marshall
Conference paper

Abstract

Determinations of α s in e + e - processes have shown a tendency in the past to fall into two categories: the method is clean and the statistical accuracy is poor, or the statistical accuracy is good but the method is beset with (e.g. fragmentation) uncertainties. In this short review, we consider methods of measuring α s which depend as little as possible on fragmentation models.
