Z/gamma* plus Multiple Hard Jets in High Energy Collisions

Understand

We present a description of the production of a di-lepton pair (through Z boson and virtual photon) in association with at least two jets.

• This calculation adds to the fixed-order accuracy the dominant logarithms in the limit of large partonic centre-of-mass energy to all orders in the strong coupling.
• This is achieved within the framework of High Energy Jets.
• This calculation is made possible by extending the high energy treatment to take into account the multiple t-channel exchanges arising from Z and gamma*-emissions off several quark lines.
