Dark energy? No sign of symmetrons

One of the candidates for 'dark energy' is the symmetron field. Researchers have developed an experiment capable of measuring extremely small forces with the help of neutrons. The measurements could have provided pointers to the mysterious symmetrons, but the particles didn't show up. This excludes the possibility of symmetrons in a broad parameter range. 'Dark energy' is going to have to be explained differently.
