Cooling particle beams to study the hottest topics in physics
From Advanced Science News, August 19, 2022: A team of researchers led by Fermilab’s Jonathan Jarvis have successfully demonstrated optical stochastic cooling. This improved technique will increase the achievable cooling rate by up to four orders of magnitude and ultimately allowing physicists to spend more time collecting experimental data.
Protons contain intrinsic charm quarks, a new study suggests
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.
Physicists spotted rare W boson trios at the Large Hadron Collider
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.
Is dark matter real? Astronomy’s multi-decade mystery
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.
Optical stochastic cooling improves particle accelerator beams
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.
Experimental demonstration of optical stochastic cooling
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.
Particle physicists want to build the world’s first muon collider
From Nature, Aug. 8, 2022: The accelerator would smash together this heavier version of the electron and, researchers hope, discover new particles.
Four (more) things you might not know about antimatter
It’s around you, it’s a part of you, and scientists are still trying to figure it out.
‘Windchime’ detector could use gravity to hunt for dark matter ‘wind’
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.
