Testing fundamental symmetries in Nature is one of the important subjects in
physics. The ATHENA experiment, located at CERN's Antiproton Decelerator
(AD) facility, aims to make precision tests of CPT and other symmetries by
comparing the properties of hydrogen with its antimatter counter part,
antihydrogen. After several years of development since the start of the AD
facility in 1999, we have recently achieved our first goal; production of
cold antihydrogen atoms in large quantity. In this seminar, based on a
plenary talk at LEAP-2003, I will describe our first production of cold
antihydrogen, together with the latest progress and the future prospects of
physics with cold antihydrogen. |
