From Science News, August 17, 2022: Emily Conover explains the “intrinsic” charm of protons. A new analysis of experimental results and theoretical calculations in Nature hopes to unveil a better understanding of one of the most important particles in the universe.
From Science News, August 15, 2022: W bosons are particles that transmit the weak force, which is responsible for certain types of radioactive decay. Last April, Fermilab researchers reported the W boson was more massive than predicted, hinting that something may be amiss with the standard model. Now a team of scientists with ATLAS at the LHC are reporting rare boson triplets which continues to test the standard model for any cracks.
From Big Think, August 13, 2022: After decades of research, astronomers cannot explain how and why galaxies exist. Fermilab’s Don Lincoln discusses the hypothesis of dark matter as the undiscovered form of matter to explain this galactic mystery.
From Techfragments, August 12, 2022: Jonathan Jarvis led a team of researchers who used the Integrable Optics Test Accelerator at Fermilab to demonstrate and explore a new kind of beam cooling technology. “Cooling” a beam reduces the random motion of the particles making the beam narrower and denser. Physicists could potentially use this new method to explore rare physics phenomena that help us understand our universe.
From Nature, Aug. 10, 2022: Scientists have successfully used a new technique at Fermilab’s Integrable Optics Test Accelerator
to cool a particle beam and make it denser. The new method may enable future experiments to create more particle collisions.
From Nature, Aug. 8, 2022: The accelerator would smash together this heavier version of the electron and, researchers hope, discover new particles.
It’s around you, it’s a part of you, and scientists are still trying to figure it out.
From Science News, August 4, 2022: A proposed experiment called Windchime, will try something new: It will search for dark matter using the only force it is guaranteed to feel — gravity. Fermilab physicist Dan Hooper chimes in on what this experiment can mean to the study of dark matter.
From Phys.org, August 3, 2022: Fermilab’s NOvA experiment reports analysis on oscillation data delivering some of the most accurate estimates to date describing neutrino oscillations and providing important hints on two important aspects of neutrino physics—the ordering of neutrino masses and the degree of charge-parity (CP) violation. These results set the stage for the next generation of “long-baseline” experiments, like Hyper-K and DUNE, which will dramatically boost our ability to probe elusive aspects of neutrino physics.
Physicists take on the mystery of the missing (and extra) neutrinos.
