Cosmic-ray Antiprotons in the Galaxy

In this talk I will discuss the origin and propagation of cosmic-ray antiprotons and their importance to dark matter research. I will examine the expected antiproton flux from cosmic-ray interactions in the interstellar medium in several simplified propagation models, and compare them with existing data to search for evident dark matter signature. I will also review and summarize the current status of relevant experiments.
