‘Milestone’ Evidence for Anyons, a Third Kingdom of Particles

May 12, 2020

Anyons don’t fit into either of the two known particle kingdoms. To find them, physicists had to erase the third dimension.

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.

A Call for Courage as Physicists Confront Collider Dilemma

August 7, 2019

Carlo Rubbia, leader of the bold collider experiment that in 1983 discovered the W and Z bosons, thinks particle physicists should now smash muons together in an innovative “Higgs factory.”
