 Description Lecture 4: Physics with Antimatter at the Antiproton Decelerator The Antiproton Decelerator (AD) is a unique facility - the world's only source of low energy antiprotons for fundamental studies of the physics of antimatter. I will discuss the physics at the AD, with an emphasis on studies of antihydrogen, the only antimatter atom that we can produce in the laboratory. Recently we have been able to capture antihydrogen, store it for more than 15 minutes, and make the first measurements of its structure. The idea is to compare it to hydrogen, to see if atom and anti-atom behave identically, as required by the Standard Model. The AD was the inspiration for Dan Brown's 'Angels and Demons'; we can also take a look at the science fiction in the book.  Material: Other occasions
