چکیده
The physics programme for an electron-positron linear collider with center of mass energy ranging from 90 GeV to 800/1000 GeV, is largely dominated by events with final state containing many jets [1] (essentially di-boson events with W,Z or Higgs decaying into jets). For an experiment on such an accelerator, the goal of the calorimeter can be either to measure well the total flow of energy (in jets) or to measure the photons, the neutral hadrons and to identify the leptons e, μ or τ . The second option seems more difficult, but our contention is that its three items can be optimised together and that, by that time, the energy flow measurement is optimised far beyond the first solution capability. This is done through a so-called energy flow algorithm which employs not only the calorimeter but also the tracker. The studies described below use a full full simulation of the calorimeter named Mokka [2] based on GEANT4.

The experimental potential of e+e− Linear Colliders to explore the properties of supersymmetric particles is reviewed. High precision measurements of masses, spin-parity, gauge quantum numbers, couplings and mixings, production and decay properties will be possible in a clean environment. These achievements will allow the underlying supersymmetry breaking scheme to be revealed, the parameters o...

whereHmn are numerical coefficients and we have introduced the shorthand L ≡ ln 1/v. The double logarithms are associated with non-cancellation between soft and collinear divergences in real and virtual graph, since limiting v suppresses real radiation but not the corresponding virtual terms. When v is small (ln v ∼ α s ) all terms αs L 2m become of the same magnitude (∼ 1) and reliable calcula...
