Antiquark Flavor Asymmetry with New Accelerator Facilities

Flavor asymmetry in light antiquark distributions is discussed. In particular, recent progress on the u-bar/d-bar asymmetry is explained. Then, we discuss possible future experimental studies.

1. Introduction
2. Present situation
3. Future u-bar/d-bar asymmetry studies 3.1 Drell-Yan process 3.2 Charged-hadron production 3.3 W charge asymmetry 3.4 Deuteron acceleration at HERA
