Quiz time: This week we’re spotlighting news about NOvA results.
But first, join Fermilab News at Work in congratulating Paul Olderr for winning last week’s quiz. The Mu2e production target team has simulated and studied at least 35 target designs over the years.
Now, show off your knowledge of the news coming out of Fermilab in this week’s quiz. A winner will be randomly selected from all lab employees and users who submit the correct answer to today’s question by noon CT today, Nov. 14.
This week’s question: NOvA scientists are studying how antineutrinos may oscillate into different flavors (for example, muon antineutrino into electron antineutrino) to find evidence of a type of symmetry violation called charge parity. What level of statistical significance do their most recent results show (in sigma), and what does that level of sigma indicate? (Hint: See “Gotta catch ’em all: new NOvA results with neutrinos and antineutrinos.”)
Good luck! We will announce the winner and answer next week.
Past winners are welcome to participate in the quiz each week. However, only one win per person will be recognized in any 30-day period. The winner is recognized in the following week’s quiz and rewarded with a small token.
Four events observed in the NOvA far detector, classified as muon (left) or electron (right) neutrino interactions, with the beam in neutrino (top) or antineutrino (bottom) mode. Each panel shows two views of the same event, and the color represents the energy deposited by particles that emerged from the interaction. The latest NOvA results comprise four data samples with 113 muon neutrino to muon neutrino, 58 muon neutrino to electron neutrino, 102 muon antineutrino to muon antineutrino and 27 muon antineutrino to electron antineutrino candidates.
