ALPHA is an experiment at CERN, whose ultimate goal is to perform a precise test of CPT symmetry with trapped antihydrogen atoms. After reviewing the motivations, we discuss our recent progress toward the initial goal of stable trapping of antihydrogen, with some emphasis on particle detection ...

“This is by far the most difficult experiment we have ever done,” he says. “We’re over the moon. About a decade ago, laser cooling of antimatter was in the realm of science fiction.” The ALPHA collaboration synthesises antihydrogen from cryogenic plasmas of antiprotons and positrons ...

For the present analysis, measurements of jet cross sections and inclusive DIS cross sections in lepton-proton collisions performed by the H1 experiment at HERA are exploited. Jet cross sections Cross sections for jet production in lepton-proton collisions have been measured by H1 at two different ...
