-Non-interference theorem in dimension 6 EFT beyond LO & 2->2 processes
+====== Non-interference in dimension 6 EFT: beyond LO & 2 to 2 processes ======
+People interested: Francesco Riva, Ken Mimasu, Benjamin Fuks
+Investigate the impact of higher order corrections or additional radiation on high energy 2->2 processes involving dimension 6 EFT operators that have been shown not to interfere at leading order.
+A simple test case may be $W^+ W^-$ production at a lepton collider. Here the EW corrections including dimension 6 operators have not been calculated but an extra photon emission would alter the helicity structure and is part of the higher order contribution.
