University of Michigan lecture archiving and related activities of the U-M ATLAS Collaboratory Project
Large scientific collaborations as well as universities have a growing need for multimedia archiving of meetings and courses. Collaborations need to disseminate training and news to their wide-ranging members, and universities seek to provide their students with more useful studying tools. The University of Michigan ATLAS Collaboratory Project has been involved in the recording and archiving of multimedia lectures since 1999. Our software and hardware architecture has been used to record events for CERN, ATLAS, many units inside the University of Michigan, Fermilab, the American Physical Society and the International Conference on Systems Biology at Harvard. Until 2006 our group functioned primarily as a tiny research/development team with special commitments to the archiving of certain ATLAS events. In 2006 we formed the MScribe project, using a larger scale, and highly automated recording system to record and archive eight University courses in a wide array of subjects. Several robotic carts are wheeled around campus by unskilled student helpers to automatically capture and post to the Web audio, video, slides and chalkboard images. The advances the MScribe project has made in automation of these processes, including a robotic camera operator and automated video processing, are now being used to record ATLAS Collaboration events, making them available more quickly than before and enabling the recording of more events.

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.

Hyperon Polarization in a Quark‐Quark Scattering Model
A continuing mystery in particle physics is the large polarization observed in inclusive hyperon production in high energy proton‐proton collisions. A model in which quarks become polarized in a direct quark‐quark scattering process is proposed to explain the observed pattern of the polarization in the hyperon system. We find that in this picture hyperon and elastic p‐p polarizations, which previously seemed unrelated, may have a simple and common origin.

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.

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.

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.

Monolithic CMOS pixel detector for international linear collider vertex detection
A monolithic CMS pixel detector is under development for an ILC experiment. This chronopixel array provides a time stamp resolution of one bunch crossing, a critical feature for background suppression. The status of this effort is summarized.

Status of the Compact Muon Solenoid Detector at the Large Hadron Collider
The Compact Muon Solenoid (CMS) detector is being constructed at the Large Hadron Collider (LHC) at CERN for the purpose of exploring new physics in proton‐proton collisions at 14 TeV. The detector is to be designed, constructed and commissioned in time for the start of the LHC in April 2007. This article summarizes the current status of the detector and foreseen program for completion.
