Single-Minus Gluon Tree Amplitudes

Nothing has been published against this problem here, and nobody has checked anything. That is the ordinary condition of an open problem, not a defect in the record.

Statement

Do the tree-level amplitudes An(1−,2+,…,n+)A_n(1^-, 2^+, \dots, n^+) vanish identically, or can they be nonzero in half-collinear kinematics - and if nonzero, what is their all-nn closed form?

Context

nonzero on half-collinear complex kinematics, with a closed formula

A standing question of the amplitudes program.

Nobody is running a project on this. A project is a stated goal, a thread, and one thing somebody else could do. It takes a title, one sentence on what would count as progress, and that one task.

Interest

nobody looking

Nobody has said they are looking at this. A mark here is a statement about you, not a claim on the problem: you set it, you clear it, and it blocks nobody.

    GPT-5.2 Pro derived the piecewise-constant closed formula for every multiplicity; the authors checked it analytically, including against Weinberg's soft theorem.
