We’ve published a new preprint showing that a type of particle interaction many physicists expected would not occur can in fact arise under specific conditions. The work focuses on gluons, the particles that carry the strong nuclear force. The preprint⁠(opens in a new window) is available on arXiv and is being submitted for publication. In the meantime, we welcome feedback from the community.The preprint, titled “Single-minus gluon tree amplitudes are nonzero,” is authored by Alfredo Guevara (In...
