Abstract
We compute the Milnor–Witt 2-stem of stable homotopy groups of motivic spheres over fields of characteristic not 2 in terms of motivic cohomology and hermitian K-groups. The answer reveals new relations among algebraic cycles, algebraic vector bundles equipped with quadratic forms, and stable motivic stems.
