Proton polarization in inclusive processes at 100, 200, 300, and 400 GeV
We have measured the polarization of the out going proton in the following high energy interactions: p+C..-->..p/sup arrow-up/+x and p+p..-->..pup-arrow+x. Our measurements span the P/sub T/ range .5..-->..1.5 GeV/c energies of 100, 200, 300, 400 GeV at the internal target area at Fermi National Accelerator Laboratory.

A Study of Inclusive Proton Polarization
The authors propose to measure the polarization of the outgoing proton in the inclusive reaction p + p {yields} p {up_arrow} + X in the region .98 > x{sub R} > .6. The measurements would include beam momenta from p{sub LAB} = 50 GeV/c to p{sub LAB} = 400 GeV/c at t = -.3 (GeV/c){sup 2}, -.8 (GeV/c){sup 2}, -1.4 (GeV/c){sup 2}, and -3.0 (GeV/c){sup 2} over the range .6 < x{sub F} < .95. The experiment would use the existing E313 polarimeter and internal target spectrometer.

Advances in the Study of Spin Effects in Nucleon-Nucleon Scattering at Small and Intermediate Momentum Transfers
There has been remarkable progress made in the field of high energy physics in the past five years. We have recently witnessed the discovery of new quantum numbers, the spectra of particles associated with these quantum numbers, and a much improved understanding of the role that all quantum numbers play in high energy interactions. With the wide assortment of experiments and studies being conducted in high energy physics at any one time, it is very easy for one to get the impression that, the activity in the field is highly unfocused. On the one hand, it is precisely this apparent unfocused nature that has given rise to much of the excitement and richness of the field. On the other hand, as one examines the situation more closely, one finds that much of the effort in the field is indeed directed toward the solution of a few central problems. One of these problems which I will continually refer to today is that of understanding the details of the structure of the elementary particles. This problem—one of the most fascinating and most difficult problems ever tackled by man-can be approached from several different angles.

Lecture archiving on a larger scale at the University of Michigan and CERN
The ATLAS Collaboratory Project at the University of Michigan has been a leader in the area of collaborative tools since 1999. Its activities include the development of standards, software and hardware tools for lecture archiving, and making recommendations for videoconferencing and remote teaching facilities. Starting in 2006 our group became involved in classroom recordings, and in early 2008 we spawned CARMA, a University-wide recording service. This service uses a new portable recording system that we developed. Capture, archiving and dissemination of rich multimedia content from lectures, tutorials and classes are increasingly widespread activities among universities and research institutes. A growing array of related commercial and open source technologies is becoming available, with several new products introduced in the last couple years. As the result of a new close partnership between U-M and CERN IT, a market survey of these products was conducted and a summary of the results are presented here. It is informing an ambitious effort in 2009 to equip many CERN rooms with automated lecture archiving systems, on a much larger scale than before. This new technology is being integrated with CERN's existing webcast, CDS, and Indico applications.

Improved Constraints on the Neutralino Cold Dark Matter Candidate from the Search for Chargino and Neutralino Production Using the OPAL Detector at 170 ÷ 172 Gev at LEP
New limits on the cold dark matter candidate, the lightest neutralino \(\left( {\tilde x_1^0} \right)\), are obtained from a search for charginos and neutralinos using a data sample of 10.3 pb−1 at the center-of-mass energies of √s =170 and 172 GeV with the OPAL detector at LEP.

Monolithic CMOS Pixel Detectors for ILC Vertex Detection
A CMOS pixel vertex detector suited for use at the International Linear Collider (ILC) is proposed. The proposed detector consists of 50µm ◊ 50µm macropixels, each with integrated bunch clock memory, on top of 5µm ◊ 5µm micropixels that record amplitude information. The micropixels integrate over all bunch crossing in a train. Using the time recorded by the macropixels, the fine position measurements made in the micropixels can be associated to only a few of the 3000 bunch crossings in a bunch train.

SLD results on B physics
Results on B-lifetimes, Bdo and Bso mixing, and B decay charm counting studies from the SLD experiment at the Stanford Linear Accelerator Center are presented. These results which exploit the small stable beam spots and high precision detector and the polarized electron beam are among the most precise measurements to date.

Ideas on DC-DC Converters for Delivery of Low Voltage and High Currents for the SLHC / ILC Detector Electronics in Magnetic field and Radiation environments
For more efficient power transport to the electronics embedded inside large colliding beam detectors, we explore the feasibility of supplying 48 Volts DC and using local DCDC conversion to 2 V (or lower, depending upon on the lithography of the embedded electronics) using switch mode regulators located very close to the front end electronics. These devices will be exposed to high radiation and high magnetic fields, 10 – 100 Mrads and 2 4 Tesla at the SLHC, and 20 Krads and 6 Tesla at the ILC.

RECENT RESULTS ON CP-VIOLATION AT THE BABAR AND BELLE B-FACTORIES
New results on CP violation measurements performed on events collected at the Υ(4S) in upto 432 fb-1 of data at the BABAR experiment and upto 770 fb-1 of data collected at the Belle experiment. The measurements provide new constraints on the unitarity triangle angles γ and β. The measurements presented include: results from BABAR and Belle on CPV using Dalitz plot analyses, measurements of the CKM angle γ using a GLW analysis of B → DK± decays and from using B → D*°K- decays and results on yCP using D° mixing.
