Abstract
| We compute the total cross section for t¯tt¯t production at next-to-leading logarithmic (NLL′) accuracy. This is the first time resummation is performed for a hadron-collider process with four colored particles in the final state. The calculation is matched to the next-to-leading order strong and electroweak corrections. The NLL′ corrections enhance the total production rate by 15%. The size of the theoretical error due to scale variation is reduced by more than a factor of two, bringing the theoretical error significantly below the current experimental uncertainty of the measurement. |
