摘要:

We point out that in the particle collider, the existence of Glauber gluons can account for the violation of the anomalous lepton angular distribution, observed in pion-induced Drell-Yan processes. It is argued that the Glauber effect is significant in the pion due to its unique role of being a Nambu-Goldstone boson and a q-qbar bound state simultaneously. We propose to discriminate the above resolutions by measuring the p-pbar Drell-Yan process.
