Software plays an important role in the optimisation and design of detectors for the
ILC. Over the past years, a first version of a coherent software system has been
developed within the ILC community. It is based on a common data format, LCIO, and on
the definition of interfaces between different parts of the simulation and
reconstruction chain. Particular emphasis is put on a highly...

We present the status of DigiSim, a package designed for parametric simulation of the
conversion of (GEANT4) energy deposits into digitally stored "hits", specifically for
the ILC detector(s). DigiSim is well integrated to two of the most widely used
reconstruction frameworks for the ILC, namely org.lcsim/java and Marlin/C++. Simple
implementations exist for the most common processes,...

The code to fit parameters of reconstructed tracks using weight matrix of
measurements and solving system of equations to minimize chi square of the track
residuals was ported from hep.lcd package to org.lcsim package. The performance of
the fitter is reported.

Marlin is a Modular Analysis and Reconstruction framework for detector simulation
studies at the ILC. It is based on C++ and consists of software modules, called
processors, which can be accessed and parametrised easily via a simple XML-based
steering file. The native transient data format used for Marlin is LCIO.
Marlin itself provides the framework only. All more specialised modules,...

"We present the software package for the simulation and reconstruction of the IV
Concept detector: IVCroot. It is based on the architecture of Aliroot, the Offline
system of Alice experiment. The architecture is discussed along with some preliminary
results"

The study uses a quick simulation of the GLD named QuickSim. For a better performance
of physics event study, we have checked several parameters for that purpose. The
physics event, say, e+ e- -> Z h, has been studied.

A calorimeter energy calibration method has been developed for ILC detectors. The
method uses the center mass energy of the accelerator as a constraint. It was shown
that using the energy conservation law it is possible to do an ECAL and HCAL cross
calibration in a way to reach a good energy resolution for the simple calorimeter hit
energy sum.
The Application of this method in LDC...

I will describe a new particle flow algorithm running in the Marlin framework.
The algorithm is designed with the goal of comparing the perfomance of different
detector parameters. First results using the Mokka simulation of variants of the
LDC detector will be presented.

We present the status of particle-flow algorithm development at Northern Illinois
University. A key element in our approach is the calorimeter-based "Directed Tree"
clustering algorithm. We have attempted to identify and tackle the essential
challenges and analyze the effect of several different approaches to the
reconstruction of jet energies and the Z-boson mass. A number of...

After the Large Hadron Collider (LHC), the next step for making progress in Particle
Physics is the International Linear Collider project which will make precision
measurements, often complimentary to those from the LHC, and provide detailed insight
into the anticipated discoveries. In order to achieve the physics goals, the
detectors at the Intenational Linear Collider must have fine...

Particle Flow Calorimetry promises an excellent jet energy resolution by
combining the momentum measurement, electromagnetic calorimeter and using
the hadron calorimeter for neutral hadron only. This technique depends on the
ability of separation of energy deposits of separate particles and thus on the
spatial density of particles in the calorimeter. We investigate the variation of
the...
