First evidence for string theory at the Large Hadron Collider

•, By Jon Butterworth
  bug in the software used to model the detectors at the Large Hadron Collider could have been covering up evidence for extra space time dimensions.

Complex software models are used to understand the results from the Large Hadron Collider. These include simulations of the particle physics in the proton-proton collisions, as well as of the material and geometry of the detectors and the strength of the various magnetic fields. As more data are accumulated, the required precision of this software increases.

A recent review recommended that the number of decimal places used to represent numbers in the software should be increased. This means all mathematical constants such as e and pi, as well as physical constants and the measured dimensions of the detectors. So far, so routine.
