Can the mirror world explain the ortho-positronium lifetime puzzle?
Abstract
Description
We suggest that the discrepant lifetime measurements of ortho-positronium can be explained by ortho-positronium oscillations into mirror ortho-positronium. This explanation can be tested in future vacuum experiments.
