Next-to-next-to-leading electroweak logarithms for W-pair production at LHC

We derive the high energy asymptotic of one-and two-loop corrections in the next-to-next-to-leading logarithmic approximation to the differential cross section of W -pair production at the LHC. For large invariant mass of the W-pair the (negative) one-loop terms can reach more than 40%, which are pa...

Zusammenfassung:We derive the high energy asymptotic of one-and two-loop corrections in the next-to-next-to-leading logarithmic approximation to the differential cross section of W -pair production at the LHC. For large invariant mass of the W-pair the (negative) one-loop terms can reach more than 40%, which are partially compensated by the (positive) two-loop terms of up to 10%.
