(credit: CERN ) In Wednesday’s issue of Nature, a new paper describes a potentially useful way associated with measuring the interactions between normal matter and exotic particles, like anti-protons and unstable items such as kaons or elements […]
A mile below ground, a sign hangs over the door to the LUX dark matter experiment telling visitors how far to Wall Drug—in both dimensions. (credit: Matthew R. Francis) Update, Sept. 6, 2021: It’s Labor Day Weekend in the US, and even though most of us are continuing to call home ” the office , […]

(credit: CERN) The exotic family of particles known as tetraquarks has a surprising new member. Dubbed T cc + , it’s the first tetraquark to contain two heavy quarks and two light antiquarks, and […]

(credit: Paul Scherrer Institut) Physicists, who dedicate their lives to studying the topic, don’t actually seem to like physics very much, since they’re always hoping it’s broken. But we’ll have to forgive them; finding out that a bit of […]
