  • December 18, 2012
    feature: A model partnership
    Bucking the “ivory tower” stereotype, particle theorists dive into Large Hadron Collider experimental searches and come up with a new way to look at the data.
  • December 11, 2012
    explain it in 60 seconds: Decay channel
    When particles decay, they transform into lighter particles. Physicists can predict how often a particle will decay into certain end products.
