Murray Gell-Mann

1929–2019 · Theoretical physics, particle physics
American theoretical physicist who devised the quark model, which explained the organization of subatomic particles and became the basis of the Standard Model of particle physics. He also introduced many other concepts in particle physics.

Biography

Born in 1929 in New York City. A child prodigy, he entered Yale University at the age of 15 and received his doctorate from the Massachusetts Institute of Technology in 1951. He worked at Princeton, the University of Chicago, and then became a professor at the California Institute of Technology. He won the 1969 Nobel Prize in Physics for his contributions to the classification of elementary particles and their interactions. He founded the Santa Fe Institute for the study of complex systems.

Key discoveries

💡 The name 'quark' comes from Joyce's novel 'Finnegans Wake' ('Three quarks for Muster Mark!'). Gell-Mann was also known as a polymath, with interests in linguistics and ornithology.
"He expressed a wish to think that the particle called the 'quark' is the last step on the path to understanding matter, but acknowledged uncertainty about what will come next."

How to Peek Inside a Particle Without Breaking It
Accelerators sometimes produce particles that don't fit the usual two- or three-quark scheme. Two such particles, Zb(10610) and Zb(10650), have been puzzling physicists for over a decade. They look like heavy cousins of pions, but with a clear sign of a four-quark composition. The question is how those four quarks are packed.

Two-Charm Baryon Caught for the First Time
In proton collisions at the Large Hadron Collider, physicists have for the first time caught a particle with two charm quarks. It is called Ξcc+ (pronounced "ksi-ksi-plus") and resembles a bead with not one but two heavy nuclei.

Quark Bricks: Assembling Heavy Particles
Heavy particles, which physicists call baryons, are like tiny families of three quarks. The common baryons are protons and neutrons, which make up everything around us. But there are also exotic relatives: instead of light quarks, they harbor charm or bottom quarks — heavy and short-lived.

A Particle on the Brink: What Holds the Mysterious X(3872) Together
In the city of elementary particles, there is a house right on the edge — X(3872). It sits exactly on the line separating it from decaying into two lighter structures: a D meson and an anti-D meson. Give it a nudge, and it would fall apart. But the house stands. Physicists have long debated what holds it together.
