Anti-Hydrogen Production Under Laser Control

`Anti-hydrogen production under laser control has been achieved in an experiment conducted at the CERN lab in Geneva. Cold anti-hydrogen (Hbar) atoms are the antimatter counterparts of hydrogen atoms. Previously antihydrogen was formed when positrons cooled antiprotons within the carefully designed electric and magnetic fields of a nested Penning trap. That the anti-atoms had formed at all was verified, but they’re not yet cold enough to be held in place.’
