A team of researchers that includes Perimeter Faculty member Freddy Cachazo has invented a new system for calculating what happens when particles interact – a result likely to have wide implications for physics and mathematics.

 
 
 
 

A Deeper Dive: On-Shell and Off-Shell

To better understand the implications of a recent paper by Perimeter Faculty member Freddy Cachazo et al., we delve deeper into the meaning of on- and off-shell particles.
