Submission + - Fermilab prepares for a future of muons (

ananyo writes: At Fermi National Accelerator Laboratory, protons were always the primary particles, coursing through the circular tracks of the the Tevatron, which until 2009 was the highest energy collider in the world. But there's a new particle making the rounds at the Batavia, Illinois campus: the muon, a heavy but short-lived cousin of the electron — interesting both for its usefulness in testing the Standard Model, as well as potentially being used someday in a powerful colliderLink text.
On 19 September, the lab announced that the US Energy Department (DOE) had granted the $40 million experiment “mission need” approval, a first step towards eventual funding. Last month, a second muon experiment, called Mu2e and priced at $200 million, received a second stage blessing from the DOE.
The g-2 experiment will focus on an anomaly in the spin rate of a muon within a magnetic field, which some theorists believe is evidence that supersymmetry could resolve problems in the Standard Model. Meanwhile, the Mu2e experiment, which aims to begin taking data in 2019, will sift through many trillions of muons to see if any happen to spontaneously morph into their cousins, the electron — something that is almost entirely forbidden under the Standard Model.
