Would an Anti-apple Fall Up?
Tests of the Gravitational Interaction between Matter and Antimatter

Scott Menary

York University

The strength and sign of the gravitational interaction between matter and antimatter (so-called “antigravity”) is still an open experimental question. I will discuss some arguments and measurements which shed light on the issue. Finally I will describe planned antigravity experiments involving antihydrogen with an emphasis on the ALPHA experiment at CERN.
