Particle Data News Today

“What might we learn from lines of research that are off the beaten track? They check accepted ideas, always a Good Thing, and there is the chance Nature has prepared yet another surprise for us.” -Jim Peebles It's been a huge week here at Starts With A Bang, and one of our busiest on record. If you thought that Pluto's demotion was the biggest news about the outer Solar System, just wait until you get to the highlight of this week:

Today Quanta published an explainer I wrote on the subject of resonance. Regular readers of this irregularly maintained blog will know that resonance is among my favorite topics in physics.

Cats may or may not be liquid, but researchers are more certain about other states of matter: namely, plasma.

"It is no good to try to stop knowledge from going forward. Ignorance is never better than knowledge." -Enrico Fermi As you probably know, the Large Hadron Collider -- site of discovery of the last fundamental particle in the Standard Model, the Higgs Boson -- is the most energetic particle accelerator in the history of humankind. When the upgrades it's currently undergoing are complete, it will reach collision energies of 14 TeV.

Credit: KOU Wei Researchers have recently extracted the proton mass radius from the experimental data. A research group at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) presented an analysis of the proton mass radius in Physical Review D on May 11. The proton mass radius is determined to be 0.67 ± 0.03 femtometers, which is obviously smaller than the charge radius of the proton. In the Standard Model, the proton is a composite particle made of quarks and gluon...
