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

Electroweak neutral weak couplings are important parameters of the Standard Model of particle physics. The product of lepton and quark couplings, C1q, C2q and C3q, can be accessed from lepton scatterings via either parity violation or charge conjugat

Positron Production at JLab Simulated Using Geant4

Autor: W. J. Kossler, S. S. Long, Latifa Elouadrhiri, Jospeh Grames, Wally Melnitchouk, Eric Voutier, Tony A. Forest

Publikováno v: AIP Conference Proceedings.

The results of a Geant4 Monte-Carlo study of the production of slow positrons using a 140 MeV electron beam which might be available at Jefferson Lab are presented. Positrons are produced by pair production for the gamma-rays produced by bremsstrahlu
