Study of stop and sbottom at LHC

In supersymmetric models a gluino can decay into $tb\tilde{\chi}^{\pm}_1$ through a stop or a sbottom. The decay chain produces an edge structure in the $m_{tb}$ distribution. Monte Carlo simulation studies show that the end point and the edge height would be measured at the CERN LHC by using a sideband subtraction technique. The stop and sbottom masses as well as their decay branching ratios are constrained by the measurement. We study interpretations of the measurement.Comment: 3 pages, 2 eps files, style files are included, talk at PASCOS'03, Mumbai, India, January 3-8, 200

Lepton Flavor Violation at the LHC

Recent results from Super Kamiokande suggest $\nu_\mu-\nu_\tau$ mixing and hence lepton flavor violation. In supersymmetric models, this flavor violation may have implications for the pattern of slepton masses and mixings. Possible signals for this mixing in the decays of sleptons produced at the LHC are discussed. The sensitivity expected is compared to that of rare decays such as $\tau\to \mu\gamma$.Comment: 14 pages, 9 figure

Library Faculty and Instructional Assessment: Creating a Culture of Assessment through the High Performance Programming Model of Organizational Transformation

In an environment in which libraries increasingly need to demonstrate their value to faculty and administrators, providing evidence of the library’s contribution to student learning through its instruction program is critical. However, building a culture of assessment can be a challenge, even if librarians recognize its importance. In order to lead change, coordinators of library instruction at institutions where librarians are also tenure-track faculty must build trust and collaboration, lead through influence, and garner support from administration for assessment initiatives. The purpose of this paper is to explore what it takes to build a culture of assessment in academic libraries where librarians are faculty through the High Performance Programming model of organizational change. The guidelines for building a culture of assessment will be exemplified by case studies at the authors’ libraries where instruction coordinators are using collaboration to build a culture of assessment with their colleagues

Assessment in Action: Academic Libraries and Student Success

Academic librarians are connecting with campus partners in novel ways to question and discover how they bring value to their institutions. To foster these partnerships, the Association of College and Research Libraries (ACRL), with funding from the U.S. Institute of Museum and Library Services, launched “Assessment in Action: Academic Libraries and Student Success” (AiA). This three-year program will to aid 300 postsecondary institutions of all types as they create engaged libraries of the future. Each selected institution has a team with a librarian and at least two people from other campus units. The librarians will participate in a formal 14-month professional development program and lead their campus teams in developing and implementing action-learning projects. The projects investigate library impact and consider different aspects of the academic library (e.g., collections, space, instruction, reference, etc.). They must ultimately be tied to student learning (e.g., course, program, or degree learning outcomes) and/or success (e.g., student retention, completion, or persistence). This session will report on the assessment work of the first 75 institutions. Learn about the questions they are exploring as they develop and implement action-learning projects on campus and how ACRL is developing this assessment community of practice

Chemotactic Collapse and Mesenchymal Morphogenesis

We study the effect of chemotactic signaling among mesenchymal cells. We show that the particular physiology of the mesenchymal cells allows one-dimensional collapse in contrast to the case of bacteria, and that the mesenchymal morphogenesis represents thus a more complex type of pattern formation than those found in bacterial colonies. We finally compare our theoretical predictions with recent in vitro experiments

Measurements in SUGRA Models with Large tan beta at LHC

We present an example of a scenario of particle production and decay in supersymmetry models in which the supersymmetry breaking is transmitted to the observable world via gravitational interactions. The case is chosen so that there is a large production of tau leptons in the final state. It is characteristic of large tan beta in that decays into muons and electrons may be suppressed. It is shown that hadronic tau decays can be used to reconstruct final states.Comment: 15 pages, 12 figure
