"The 4th Concept detector for the International Linear Collider"
A small group is now designing a new detector for e+e- physics at a future
linear collider, involving new ideas in TPCs, calorimetry, muon systems,
and machine-detector interface.. Our goal is to design, at least at this
conceptual stage, the "best detector in high energy physics".

"What heavy flavor decays can teach us about light meson physics
and what you need to know about light quark dynamics to extract
useful information from heavy flavor decays"
Abstract:
A key window on physics beyond the Standard Model is provided
by heavy flavor decays and the precision measurement of the CKM
matrix elements. However, the underlying weak interaction is
largely obscured by strong final state interactions. Consequently,
we have to understand the light quark dynamics involved if we are
to extract precise information from heavy flavor decays. How to do
this will be reviewed.

"Searching for New Physics in leptonic and radiative decays with BABAR"
Rare decay processes, which are suppressed or forbidden within the
Standard Model, can have rates or other observables which are
significantly modified by contributions from "New Physics". Thus,
these processes are sensitive probes of a variety of scenarios of
New Physics at energy scales well beyond the electroweak scale. In this
talk I will present recent results of searches for rare leptonic and
electroweak flavour-changing neutral-current decays of B mesons, as well
as lepton flavour violating tau decays, from the BABAR experiment at SLAC.
I will also discuss some of the implications for possible physics beyond
the Standard Model which result from these measurements and the
prospects for future measurements from B factories.

"The birth of a future light source in Wilson basement"
With decades of successful CESR running for high energy physics coming to an end, LEPP physicists have begun looking beyond Ithaca by getting involved in experiments and machine design of large international projects such as LHC and ILC. In the meantime, the Wilson lab is bracing towards the transition to a dedicated light source facility in the course of several years. The landscape of existing and envisioned light sources worldwide, which I will paint, reflects a vibrant and competitive environment of synchrotron radiation science community: the new low emittance storage rings continue to push the envelope of x-ray brightness, while the free electron lasers seek to realize the long-awaited goal of achieving lasing at Angstrom wavelength. Cornell seeks to enter this arena as a leader by developing and operating the next generation light source on campus. The key part to this bet is a construction of a very high brightness & intensity electron photoinjector that is now being commissioned in the basement of Wilson building. I will seek to communicate the inspiration behind the project, summarize the aspirations from R&D now in progress, and convey some of the perspiration that occurs in the process of pushing the state-of-the-art in several dimensions as the lab develops a new class of particle accelerators. |

"The Search for New Physics in B Decays at LHCb"
The speaker will give an introduction to the CKM mechanism for CP Violation and
give an overview of what has been learned by the B factories. The speaker will then discuss
LHCb, an experiment designed to search for new physics in decays of B mesons.

"New D-mixing results from BaBar "
There have been several exciting new results in charm physics
recently. The main focus of the talk will be a preliminary study
of 384 fb-1 of BABAR data in which we see evidence for mixing in D0
decays to K+ pi-. I will touch on other new results in charm mixing
and spectroscopy as time allows.

"DREAM Calorimeter"
High-precision jet spectroscopy will be increasingly important in future high-energy
accelerator experiments, particularly at a Linear e+e. Collider. In this talk, I will
present recent results of the DREAM (Dual REAdout Method) project, in which we
have built and tested a novel type of calorimeter that seems to be well suited for this
task. The key aspect of this detector is the simultaneous measurement of the scintillation
light and the .Cerenkov light generated in the shower development process. By
comparing these two signals (which are provided by different types of optical fibers),
the electromagnetic shower fraction can be measured event by event, both for single
hadrons and for jets. Fluctuations in this fraction are the dominant contribution to the
hadronic energy resolution. They are also responsible for the signal non-linearity and
the non-Gaussian response function typical for hadron calorimeters. The dual-readout
technique makes it possible to eliminate the effects of these fluctuations. As a result,
the DREAM calorimeter has impressive performance characteristics. A comparison of
the two signals also reveals interesting details about the shower development process.
I will also discuss application of the DREAM principles in homogeneous calorimeters,
which has the potential of providing ultimate calorimeter performance. Recent results
of beam tests of a crystal electromagnetic calorimeter backed up by the fiber detector
mentioned above will be presented.

"The LHC/ILC Connection"
The LHC will start data taking next year. The planned International
Linear Collider (ILC) could start operations in the second half of
this decade. In all investigated physics scenarios the ILC can
contribute substantially. Besides the complementarity of both machines,
several physics questions can only be answered in a combined analysis
of the data of the LHC and the ILC. Important examples, including results
from the LHC/ILC workshop taking place at Fermilab, are discussed.
