Kinematic Fits in the Presence of Photon Radiation
Kinematic fits are an important tool to improve jet energy
resolutions. A special technique to take into account the unprecedented
amounts of collinear photon radiation expected at future e+e- Linear
Colliders has been developped. As a next step, it's impact on
typical measurements, for instance in the Higgs sector, should be
studied, including the dependence on the different beam parameter sets
under discussion for ILC and/or CLIC.

Chargino / Neutralino Mass Determination
One task of a future e+e- Linear Collider will be the precise
characterisation of new particles. Using Supersymmetry as a test case,
different techniques to extract the mass of exotic particles which
shall be compared, especially in the situation where two new particles
are mass degenerate and the decay products have a finite decay width
themselves. Besides the reachable precision, the influences of detector
resolutions and the e+e- beam properties should be studied.

Simulation of a Complete ILC Bunch Train
At the ILC, a novel read-out concept is forseen, where all data will
be stored in the detector components' electronics during a complete
train of 3000 collisions within 1 ms, and everything will be
read-out, reconstructed and pre-selected in the following break of 199 ms.
As additional complication, the various subdetectors differ in
measurement duration and time stamping capabilities. Besides the desired
e+e- events, also beam backgrounds and two-photon processes will create
detector activity.
In order to study the impact of different beam parameter, detector
technology and read-out choices, a full bunch train needs to be
simulated.
