What is the Correct pi- p -> omega n Cross Section at Threshold?
G. Penner, U. Mosel
Abstract
The pi- p -> omega n threshold cross section measured in the seventies resisted up to now a consistent theoretical description in line with experiment, mainly caused by too large Born contributions. This led to a discussion in the literature about the correctness of the extraction of these data points. We show that the extraction method used in these references is indeed correct and that there is no reason to doubt the correctness of these data.
