Antibaryon matter.

  1. Aug 31, 2009 #1
    I have a question about the nature of matter on earth, the most stable form of hadrons which exist on earth are made from protons and neutrons, which are made up of quarks. Now, i know antiquarks exist and so too antibaryons, but is any solid object on earth made up of antibaryons?

    Also, has the antibaryon been observed in lattice structures or has it been observed only as an individual fragment of an accelerator collision, or is it just a 'deduced' particle(that is to say, was it indirectly observed)?

    No. Such an object would react violently in conatct with matter.

    No. One needs to make a lot of them and then handle them, all without contact with matter.

    The two aren't mutually exclusive. They've been seen in accelerator experiments and in cosmic rays.
