Particle physicists have a hard time identifying all the elementary particles created in their particle accelerators. But now researchers at
Chalmers researcher Philippe Tassin and his colleagues at the Free University of Brussels have designed a material that manipulates the so-called Cherenkov cone so that also particles with high momentum get a distinct light cone angle too.
“The result is that even particles with large momentum can be efficiently separated and identified,” says Philippe Tassin.
