The Balloon-borne Experiment with Superconducting Spectrometer (BESS) launched a cosmic-ray spectrometer from Antarctica on 13 December.
A new technique for cooling antiprotons has been tested at CERN's Antiproton Decelerator (AD), yielding 50 times more trapped antiprotons per cycle than ever before.
The new method consists of exciting caesium atoms from an oven with two lasers, and then introducing the caesium into a positron trap.
This is an important step towards the goal of producing antihydrogen atoms cold enough – that is, slow enough – for precision spectroscopy.
The antiproton may soon be better known than the proton, and an ion that is more hydrogen-like than hydrogen may become the subject of high-precision laser spectroscopy experiments. John Eades describ...
Given the apparent absence of antimatter at the cosmic scale, it might seem strange that a recent paper from the ASACUSA collaboration on quantum tunneling effects in collisions between antiprotonic h...
From providing a window on fundamental symmetries to probing the strong interaction, LEAP'03 covered the many parts played by low-energy antiprotons from accelerators, as John Eades reports.
The ASACUSA collaboration has reinforced its status as a paragon of precision physics by following up its impressive six parts in 108 measurement of the antiproton's charge and mass with new measureme...
Relying on ionization of the cold antiatoms when they pass through a strong electric field gradient, the ATRAP measurement provides the first glimpse inside an antiatom.
Physicists working at CERN's Antiproton Decelerator (AD) have announced the first controlled production of large numbers of antihydrogen atoms at low energies.
