Standard Model

From Oak Ridge National Laboratory, Jan. 26, 2021: The COHERENT particle physics experiment at Oak Ridge National Laboratory has firmly established the existence of a new kind of neutrino interaction. To observe this interaction, scientists used CENNS-10, a liquid argon detector built at and on loan from Fermilab.

Matter and antimatter particles can behave differently, but where these differences show up is still a puzzle. Scientists on the LHCb experiment at the Large Hadron Collider study much more subtle differences between matter particles and their antimatter equivalents. A recent analysis allowed them to revisit an old mystery — an asymmetry between asymmetries.

From Quanta Magazine, Oct. 22, 2020: Quanta Magazine creates a new visual representation of the Standard Model, building on a scheme developed by Fermilab scientist Chris Quigg.

With this six-minute video, Fermilab scientist Don Lincoln launches a special series called Subatomic Stories. You will learn a little bit about both the exciting subatomic world and the entire cosmos — and see how the two are inextricably linked. Each episode will focus on a specific topic, but the series will tell a much broader story.

From Exascale Computing Project, May 28, 2019: Fermilab scientist Andreas Kronfeld is featured in this piece on the Excascale Computing Project, quantum chromodynamics and lattice QCD. Kronfeld, the principal investigator of ECP’s LatticeQCD project, explains how exascale computing will be essential to extending the work of precision calculations in particle physics to nuclear physics. The calculations are central for interpreting all experiments in particle physics and nuclear physics.

Scientists think that a Higgs force does exist. But it’s the Higgs boson’s relationship to that force that makes it a bit of a black sheep. It’s the reason that, when the Higgs is added to the Standard Model of particle physics, it’s often pictured apart from the rest of the boson family.
