From New Scientist, April 15, 2020: Differences between matter and antimatter, called CP violation, have been measured in some particles, called quarks, but the level isn’t nearly enough to explain the observed imbalance between matter and antimatter. The T2K collaboration has observed hints that CP violation in neutrinos may be able to make up the difference. DUNE spokesperson Ed Blucher of the University of Chicago comments on the result.

New results from the T2K experiment in Japan rule out with 99.7% confidence nearly half of the possible range of values that could indicate how neutrinos behave compared to their antimatter counterparts.

From Nature, April 15, 2020: In a mirror world, antiparticles should behave in the same way as particles. But it emerges that neutrinos, electrons and their more exotic cousins might not obey this expected pattern. Fermilab scientist Jessica Turner and Durham University scientist Silvia Pascoli provide a commentary on T2K’s recent neutrino result, CP violation, and how other neutrino experiments, including the international Deep Underground Neutrino Experiment, hosted by Fermilab, will make more precise measurements of the mysterious neutrino’s behavior.

From The New York Times, April 15, 2020: An international team of 500 physicists from 12 countries, known as the T2K collaboration, reported that they had measured a slight but telling difference between neutrinos and their opposites, antineutrinos. Fermilab Deputy Director Joe Lykken comments on the result and how the international Deep Underground Neutrino Experiment, hosted by Fermilab, may be able to make a definitive discovery of CP violation.

In this imaginative film, Symmetry writer Sarah Charley depicts a short story in which a physicist is unable to cook what he wants with the ingredients he has. It’s not easy to get the grocery while sheltering in place, so he decides to use the physics at work in the Large Hadron Collider to get what he needs.

From Nature Physics, April 6, 2020: The Physics Beyond Colliders study was launched three years ago to explore the future physics projects below the high-energy frontier, including explorations of the dark sector and precision measurements of strongly interacting processes. The methodology employed to compare the reach of those projects has raised interest in the collider, neutrino and nonaccelerator communities.

The ADMX experiment trains scientists to deal with real signals—by creating fake ones.

From Quanta Magazine, March 30, 2020: Three progressively heavier copies of each type of matter particle exist, and no one knows why. A new paper by Steven Weinberg takes a stab at explaining the pattern, and summarizes a paper by Fermilab scientists Bogdan Dobrescu and Patrick Fox on the spread of the particles’ masses.

From Nature Physics, April 2020: Fermilab scientist Pushpa Bhat and her University of Melbourne scientist Geoffrey Taylor discuss particle physics experiments in the United States and Asia and how interest in the development of next-generation colliders has been rekindled.

From Semiconductor Engineering, April 6, 2020: Fermilab, Brookhaven National Laboratory and Lawrence Berkeley National Laboratory have built an enormous superconducting magnet — one of 16 — that will be used in the High-Luminosity Large Hadron Collider particle accelerator project at CERN in Europe.
