This episode features an edition of Particle/Counter Particle. In this science debate show, two physicists discuss the possible existence of “sterile neutrinos,” a theorized fourth kind of neutrino. If sterile neutrinos exist, it would be a radical discovery, adding a new building block to the Standard Model of Particle Physics.

From PBS, October 6, 9:00 pm CT: Tune in to the PBS premiere of Particles Unknown-the hunt for the universe’s most common yet elusive particle, this Wednesday on your local PBS channel. Starting with Ray Davis’ quest for neutrinos that began in 1965, Nova explores Fermilab’s search for sterile neutrinos and interviews Sam Zeller and Angela Fava from the Neutrino Division. Check your local PBS station programming to confirm the date and time of Particles Unknown.

Neutrinos are weird. Scientists didn’t expect them to change type as they travel, but they do! So how do we study this weird phenomenon of neutrino oscillation? On this episode, neutrino physicist Kirsty Duffy and special guest Anne Norrick will explore how to build a long-distance neutrino experiment.

From Scientific American, September 14, 2021: Fermilab theorist Marcela Carena writes about the ever changing behavior of muons and the first result of the Muon g-2 experiment that suggested muons were not acting as current theory prescribes in an article titled, “Weird muons may point to new particles and forces of nature,” posted in Scientific American.

From the Black Hills Pioneer, Sept. 2, 2021: Fermilab design manager for DUNE Joshua Willhet takes readers 4,850 feet underground to view and describe the excavation of the tunnels that will make way to the caverns of the LBNF for DUNE.

CERN deepens its collaboration with the US-based neutrino experiment with the provision of two enormous stainless-steel vessels for DUNE’s cutting-edge liquid-argon detectors.
