Muon

• It neither describes gravity nor the unknown components that make up most of the energy density in the universe: dark matter and dark energy.
• Particle physicists are therefore on a treasure hunt looking for any possible deviation from “expected” behaviour that could hint at new physics.
• One fundamental building block in the Standard Model is the muon, a particle similar to an electron but 200 times more massive.
• The muon has a long history of revolutionising particle physics – even its discovery was a shock.
• Any missing pieces in the Standard Model would modify the rate by an amount slightly higher or lower than predicted, making this a powerful search tool for new physics.

Boosting accuracy

• While the statistical uncertainty has been reduced, other improvements were needed to make the measurement even more precise.
• The magnetic field direction determines the axis of the wobble, so keeping the temperature fluctuations of the magnet under control was crucial.
• Differences in temperature also cause the magnet pieces to expand and contract, which changes the magnetic field slightly.
• At our level of accuracy, even a change one thousandth of a millimetre could have a huge effect on the wobble.
• For this reason, a thermal coat was installed around the ring and a cooling system in the experimental hall.

• IDEX Corporation (NYSE:IEX) today announced that it has entered into a definitive agreement to acquire micro-precision technology manufacturing company Muon B.V. and its subsidiaries (Muon Group) for cash consideration of 700 million.
• Muon Group is an IDEX-like business, producing highly engineered products used in mission-critical applications where customers demand exacting quality standards.
• Their companies are leaders in their fields, and we are excited to welcome them and their outstanding management team to the IDEX family.
• Muon Group is privately held by Rivean Capital, a European mid-market private equity firm, which acquired the company in 2018.

• VANCOUVER, British Columbia, May 27, 2021 (GLOBE NEWSWIRE) -- FIREWEED ZINC LTD. (Fireweed) (TSXV: FWZ) is pleased to announce that it has partnered with Ideon Technologies (Ideon) to undertake a muon tomography survey this summer at the Macmillan Pass project, Yukon, Canada.
• This is potentially game-changing technology that we are leveraging to become a first mover in using borehole muon tomography surveys for zinc exploration.
• The borehole muon tomography technology has been developed by Ideon Technologies ( www.ideon.ai ), a spin-off from TRIUMF (Canadas national particle accelerator laboratory) and a world pioneer in the application of cosmic-ray muon tomography.
• Typically, a borehole muon survey will take on the order of weeks to months to complete, depending on geology, depth of borehole, and imaging target.

• Combined, the two results show strong evidence that our best theoretical model of the subatomic world is incomplete.
• The strong evidence that muons deviate from the Standard Model calculation might hint at exciting new physics.
• "Today is an extraordinary day, long awaited not only by us but by the whole international physics community," said Graziano Venanzoni, co-spokesperson of the Muon g-2 experiment and physicist at the Italian National Institute for Nuclear Physics.
• In its first year of operation, in 2018, the Fermilab experiment collected more data than all prior muon g-factor experiments combined.
