The simulation tools session was divided into three main areas of concentration: physics event simulation and event generators, full detector simulation and event reconstruction frameworks, and fast simulation and physics analysis frameworks. Although the primary purpose of the plenary session talk was to summarize the contents of the parallel session presentations for those unable to attend, the intent of this write-up is to attempt to point out features in common among the ongoing efforts and present a personal view of some goals for the future. The reader is directed to the individual write-ups for details on the specific topics discussed during the workshop. A brief summary and synthesis of topics presented during the tools parallel sessions.

A new generation of semi-conducting pixel sensors for detecting minimum ionising particles (m.i.p.) was designed and first prototypes were fabricated in a standard CMOS technology, guided by the very high vertex detector performances demanded in future collider experiments. The device architecture resembles CMOS cameras, a recent alternative to CCD sensors for visible light imaging. The performances of the first prototype of Monolithic Active Pixel Sensors (MAPS), called MIMOSA, were evaluated with high energy π− beams at CERN. Preliminary test results demonstrate that the sensors detect m.i.p.s with very high efficiency and signal-to-noise ratio and provide excellent spatial resolution.

Progress is reported on research and development into the technologies and techniques for the construction of a beam profile monitor for a linear collider interaction region. Based upon measuring in detail the copious production of electron-positron pairs through beam-beam interaction, such a pair monitor has been proposed previously. Studies and simulation results are based on the JLC parameter set, but it is believed that this method can be exploited for other linear colliders.

In this talk, the search results on Standard Model Higgs boson using LEP data collected at energies up to 209 GeV are reported. An excess of 2.9 σ beyond the background expectation is found, consistent with the production of the Hoggs boson with a mass near 115 GeV/c2.

The ability to distinguish the flavor of jets formed in an event is a very important parameter to evaluate, when designing a high performance vertex detector to use in a future e+e− linear collider. In this work we concentrate on a CCD (Charged Coupled Device) pixel vertex detector. We first evaluate the basic tracking performance. We then estimate the flavor tagging performance of the present detector layout, using a neural network approach. We conclude by studying the energy dependence of the performance.

The physics potential is summarized for e+e− linear colliders operating at center-of-mass energies up to s=1 TeV in the first phase, and at multi-TeV energies in the second phase. These machines will be ideal instruments to investigate the mechanisms for the breaking of the electroweak symmetries, the fundamental Higgs mechanism or dynamical alternatives. In supersymmetric theories, the spectrum of new particles and their interactions can be explored comprehensively and with high precision. The mechanism of supersymmetry breaking can be studied experimentally and the underlying fundamental theory can be reconstructed, eventually at scales near the Planck scale where particle physics and gravity are linked. The structure of space and time will be probed at distances down to 10−18 cm in scattering experiments. Precision studies of the electroweak gauge bosons, the top quark and QCD supplement the physics program of these machines.

We briefly describe the principles of operation of the program package SIMDET, a parametric Monte Carlo program to simulate the response of a detector for the TESLA linear collider. Main detector components are implemented according to the TESLA Conceptual Design report, with a tracking system, an electromagnetic and a hadronic calorimeter, a vertex and a luminosity detector. Using the results from the ab initio Monte Carlo program BRAHMS, track parameters and calorimetric deposits are treated in a realistic way. Pattern recognition is emulated using cross references between generated particles and detector response. An energy flow algorithm defines the output of the program. Further improvements and completions of SIMDET are also discussed.

Prospects for the study of B physics with a sample of 109 hadronic Z0 decays, produced with a highly polarized electron beam, are discussed. The discussion is based on extrapolations made from current experience at LEP and the SLC, and includes both electroweak coupling measurements as well as the study of CKM parameters via exclusively reconstructed B hadron decays.
