(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: Brookhaven National Lab) On Wednesday, scientists reported successfully cooling atoms made of antimatter using an ultraviolet laser. The cooling process deployed here works on normal matter, so it was also expected to work just fine with the antihydrogen used for these experiments. Rather […]
