We know protons and neutrons are made of quarks, but are quarks made of something even smaller? UIC physicists working on the CMS detector at Fermilab appear in Fermilab Today (3/16/12)
for their recent work searching for substructure inside a quark. UIC physicists Professor Nikos Varelas
and Dr. Lenny Apanasevich
, together with UIC graduate student Inga Bucinskaite
, are highlighted for their key contributions to a new paper that sets the best lower limit on possible quark substructure to 10-20
meters. So far the quarks appear to be fundamental particles with no substructure.
