Light ions at the LHC: first results from oxygen–oxygen and neon–neon collisions
This summer, the Large Hadron Collider (LHC) delivered its first-ever collisions between light ions, opening a new chapter in the study of nuclear structure and the quark–gluon plasma (QGP) – the extreme state of matter that existed in the first…

The Asymmetry of the Universe: First Observation of CP Violation in Baryons
“What is that which always is and has no becoming, and what is that which becomes and never is?” — Plato, Timaeus 27d–28a It may sound like pure philosophy, yet for physicists it speaks to one of the most profound mysteries in physics: the matter–…

SMOG(2) at LHCb: a space experiment and a bowling alley
A famous aphorism, sometimes attributed to Max Planck, goes “When you change the way you look at things, the things you look at change". Since 2011, the LHCb experiment at the LHC has employed a System for Measuring Overlap with Gas (SMOG) to inject…

Tracing the Path to Precision: The Historical Evolution of Electroweak Physics at the LHC
The unification of the electromagnetic and weak-nuclear forces into an electroweak theory was one of the major breakthroughs of 20th century particle physics. In the 1960s, Steven Weinberg, Sheldon Glashow, and Abdus Salam proposed that these two…
