Uncharted Logarithmic Structures in QCD Transverse-Energy Flow.
We investigate the QCD transverse-energy (E_{T}) flow distribution within an azimuthal region of phase space, defined by an angular interval Δϕ on the plane transverse to a chosen reference axis. Vetoes on the resulting E_{T} are widely employed at the LHC to isolate missing transverse momentum in final states with inv...
