Growing Anomalies at the Large Hadron Collider Raise Hopes

May 26, 2020

Collider physicists report that several measurements of particles called B mesons deviate from predictions. Alone, each oddity looks like a fluke, but their collective drift is more suggestive.

Neutrino Asymmetry Passes Critical Threshold

April 15, 2020

The first official evidence of a key imbalance between neutrinos and antineutrinos provides one of the best clues for why the universe contains something rather than nothing.

Why Do Matter Particles Come in Threes? A Physics Titan Weighs In.

March 30, 2020

Three progressively heavier copies of each type of matter particle exist, and no one knows why. A new paper by Steven Weinberg takes a stab at explaining the pattern.

Top Dark Matter Candidate Loses Ground to Tiniest Competitor

November 27, 2019

Physicists have long searched for hypothesized dark matter particles called WIMPs. Now, focus may be shifting to the axion — an ultra-lightweight particle whose existence would solve two mysteries at once.
