High twist contribution to the longitudinal structure function FL at high x
Abstract
We performed NLO QCD fit of combined SLAC/BCDMS/NMC DIS data at high x. Model independent x-shape of high twist contribution to structure function FL is extracted. Twist-4 contribution is found to be in fair agreement with the predictions of infrared renormalon model. Twist-6 contribution exhibits weak tendency to negative values, although in the whole is compatible with zero within errors.
