In high-energy collisions, luminosity, or beam brightness, isn't the only thing to consider; low background noise at the detectors is also important. When wayward particles bounce around inside detectors, they can mimic real collisions, muddy results, and even damage parts of the collider.
It looks like a simple silver trailer, but it's more like a shoe store on wheels. Mike Sitarz pulls his metal trailer, better known among Fermilab employees as the "shoemobile," behind the Technical Division industrial buildings at 8 a.m. every Tuesday.
Students around the world are familiar with the periodic table of elements, a chart that outlines how protons, neutrons, and electrons form more than 100 different types of atoms.
Few periods in history were shaped by science as much as the 1950s. The Cold War was in full swing. The space race was finishing its first lap with Sputnik's launch. The Manhattan Project remained fresh in everyone's minds.
The weak force is responsible for the decay of matter: unstable particles made of heavy quarks and antiquarks decay into particles made of their lighter cousins.
