Positivity bounds for Sivers functions
arXiv:1003.4913 · doi:10.1016/j.physletb.2010.11.045
Abstract
We generalize a positivity constraint derived initially for parity-conserving processes to the parity-violating ones, and use it to derive non-trivial bounds on several Sivers functions, entering in the theoretical description of single spin asymmetry for various processes.
