Physics @ ILC: Higgs
The precise determination of the properties of the Higgs boson isone of the main goals of the ILC. Of particular importance are itsmass, mH, the total production cross section, (e
+e HZ), andthe Higgs branching ratios.

Physics @ ILC: Top
At the ILC, the top mass, mt, and top width, t, can bedetermined with high precision. The measurement of these fromthe direct reconstruction ofe+e tt events is studied. Also, thetop quark forward-backward asymmetry provides a potentiallyinteresting test of the SM.

Conclusions
Physics @ ILC: Strong EWSB
If Strong Electroweak Symmetry Breaking is realised in nature, thestudy ofWW-scattering processes is particularly important. At theILC, the W+W W+W and W+W ZZ vertices can beprobed via the processes e+e eeqqqq where the final statedi-jet masses are from the decays of two W-bosons or two
Z-bosons.

Conclusions
Jet-Energy Resolution
One of the most direct measures of detector performance at theILC is the jet-energy resolution. Precise di-jet mass reconstructionand separation of hadronically decaying W and Z bosons areessential for many physics channels. The ultimate jet energyresolution is achieved when every particle in an event, charged andneutral, is measured with the best possible precision and accuracy.

Analysis and ResultsConclusions
Particle Flow
Particle Flow is a calorimetric method for reconstructing jet energies.
Traditionally, jet energies have been
measured by taking the sum of the
energies deposited in the hadronic and
electromagnetic calorimeters.
The particle flow approach takes a
highly granular calorimetry system
and combines it with the trackingdevices to measure the energy and
momentum of every visible particle.

Analysis and ResultsConclusions
Particle Flow
The energy of charged particles is
measured by the tracking detectors;
that of photons by the electromagneticcalorimeter. The hadronic calorimeter
is then used only to measure the
energy of neutral hadrons.
The reduced dependence on thehadronic calorimeter will lead to an
unprecedented jet energy resolution.

CALICECAlorimeter for LInear Collider Experiment
A high granularity calorimeter system optimised for the particleflow measurement of multi-jet final states at the ILC running, with
centre-of-mass energy between 90 GeV and 1 TeV.
The unprecedented granularity of the CALICE calorimeterprototype provides an opportunity to test the Particle Flow
concept. Work is in progress to check the output quality of thePFA programs. Due to large amount of test beam data, itbecomes possible to use real events instead of simulated ones asinput information for these programs.

The stdhep files were then run through a Mokka Simulation
of the ILD detector in the barrel region (/4), generating slcio files.
These in turn were run through Marlin Reconstruction, creatingnew slcio files to be analized with the tools we have developed.

Analysis and ResultsConclusions
Conclusions
We find that the energies of photons and pi0s arereconstructed robustly with a rather Gaussian response
function.Charged particles are reconstructed with better precision, butexhibit long non-Gaussian tails particularly at low pT where itis quite probable to double-count track-based and calorimeterenergy due to curling tracks.
The neutral hadron response functions are broad as expectedand show substantial particle-type dependent differences.
