We present an analysis of the c and b fragmentation functions which includes in a consistent fashion leading and next-to-leading perturbative contributions, effects due to soft gluon emission and a parametrization of effects of non-perturbative origin. We show that the data on D meson production at intermediate energy constrain the parametrization of the effects of non-perturbative nature. We can therefore make a prediction for the B fragmentation function. Results for the B, D and D * fragmentation functions at LEP energy are given, and compared with existing data. © 1992.

Abstract
We present an analysis of the c and b fragmentation functions which includes in a consistent fashion leading and next-to-leading perturbative contributions, effects due to soft gluon emission and a parametrization of effects of non-perturbative origin. We show that the data on D meson production at intermediate energy constrain the parametrization of the effects of non-perturbative nature. We can therefore make a prediction for the B fragmentation function. Results for the B, D and D * fragmentation functions at LEP energy are given, and compared with existing data. © 1992.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
