Subatomic particles such as quarks can pair up when linked by ‘strings’ of force fields — and release energy when the strings are pulled to the point of breaking. Two teams of physicists have now used ...

Exotic spin-dependent interactions represent a promising avenue for probing physics beyond the Standard Model. These interactions, hypothesised to be mediated by new light bosons, couple to the ...

Scientists have taken a major step toward solving a long-standing mystery in particle physics, by finding no sign of the particle many hoped would explain it. Subscribe to our newsletter for the ...

A committee-supported project or activity that has been completed and for which output dissemination has begun. Its committee has been disbanded and closeout procedures are underway. Elementary ...
