In physics terms the difference between tardyon and superbradyon

is that tardyon is any particle with non-zero mass (i.e. one that travels more slowly than the speed of light) while superbradyon is a particle with positive mass and positive energy and a superluminal critical speed in vacuum, possibly an ultimate constituent of matter similar to preons.
