Prospects for a Measurement of ${\alpha }_s$ via Scaling Violations of Fragmentation Functions in Deeply Inelastic Scattering

Abstract

The prospects for a determination of the strong coupling constant ${\alpha }_s$ via scaling violations of fragmentation functions in deeply inelastic scattering are studied. The statistical error in the case of an integrated luminosity of $250p{b}^{-1}$, and the theoretical errors due to the various parton density parametrizations and to the factorization scale dependence are estimated.
