The charge asymmetry from Pomeron-Odderon interference in hard diffractive pi+pi- -electroproduction

The interference of Pomeron and Odderon amplitudes gives rise to a charge asymmetry in the diffractive electroproduction of a pi+pi- -pair. We calculate this charge asymmetry in perturbative QCD in the Born approximation and on the leading Q^2-level. The numerical evaluation shows a sizeable asymmetry in an experimentally accessible kinematical region. We find a characteristic m_{pi+pi} -dependence mainly dictated by the relevant Breit-Wigner-amplitudes and the corresponding phase-shifts.Comment: 4 pages, 3 .eps-figures; Talk given by Ph.H. at the QCD-N'02 workshop in Ferrara; Typos corrected, one reference adde

Striking A Balance: An Exploration of Staff-Camper Relationship Formation

Previous research highlights a range of positive developmental outcomes associated with attending summer camp. Close staff-camper relationships likely contribute to positive development, but little is known about how these bonds are formed. The current study utilized constructivist thematic analysis of interviews with campers (n = 8) and staff members (n = 7) at an overnight summer camp to examine the factors and processes that promote or inhibit close staff-camper relationship formation. The main themes identified were striking a balance, level of experience, and relationship-promoting behaviors. Staff members experience apparent paradoxes in their roles (e.g., relating to campers while also exerting authority), but navigate these tensions by using relationship-promoting behaviors and through increased experience. These findings suggest that staff training and supervision should emphasize relationship-promoting behaviors, continue throughout the summer, and be informed by campers’ perspectives. Additionally, camp administrators should capitalize on accrued experience by prioritizing staff retention

Quark Soup al dente: Applied Superstring Theory

We discuss the application of the AdS/CFT correspondence to possibly gain new physical insights for the strongly coupled quark-gluon plasma.
