Recent determinations of the proton electric to magnetic elastic form factor ratio from polarization transfer measurements at Jefferson Lab indicate an unexpected and dramatic discrepancy with the elastic form factor ratio obtained using the Rosenblu

New measurement of charge asymmetry $x{F}_3$ from HERA

Autor: L. Schoeffel, Latifa Elouadrhiri, Jospeh Grames, Wally Melnitchouk, Eric Voutier, Tony A. Forest

After presenting the recent measurements of neutral current cross section in DIS at HERA, we explain the effect of the $\gamma-Z_0$ interference at the electro-weak scale, visible on these data. Then, the beam charge difference $x{F}_3$ is measured a

We are installing at CEA-Saclay a demonstration setup for an intense positron source. It is based on a compact 5.5 MeV electron linac used to produce positrons via pair production on a tungsten target. A relatively high current of 0.15 mA compensates

Publikováno v: AIP Conference Proceedings.

We discuss the basics of polarized positron production by low energy polarized electrons. Efficiency of conversion ∼0.1–1% might be interesting for the Continuous Electron Beam Accelerator Facility (CEBAF) and the International Linear Collider (I

Physics with Cold Polarized Positronium

Autor: David B. Cassidy, Latifa Elouadrhiri, Jospeh Grames, Wally Melnitchouk, Eric Voutier, Tony A. Forest

Publikováno v: AIP Conference Proceedings.

Positronium (Ps) atoms exist in different spin configurations that determine their fundamental properties, such as energy level structure, decay rate and response to a magnetic field. The nature of interactions between Ps atoms is also strongly influ
