Antimatter Decay Problem

  1. I wanted to know If we have a antimatter it decays ? Actually I am asking Is antimatter decay ?

    Are you asking if antimatter decays? If so, then yes, it decays similar to normal matter.

    Or doesn't decay, as the case may be. Electrons don't decay, so positrons don't decay. Neither do free protons or antiprotons.

    Of course. I was more referring to how different isotopes of normal matter decay. The antimatter versions of those isotopes would also decay. I probably should have worded my response better.
  6. How different is antimatter decay allowed to be from matter decay, if CPT is not violated but CP is?

    It's as different as the asymmetry caused by CP violation.

    The question "does it decay at all?" is independent of CP violation, just the lifetime can differ.
