Topic：THE LOW-ENERGY FRONTIER OF THE STANDARD MODEL
Speaker: Prof. Achim Denig (Johannes Gutenberg-Universität Mainz )
Date：12月7日(周四)上午10:00
Place： 物理楼南408会议室
Abstract:
We discuss various low-energy precision tests of the Standard Model
presently carried out by scientists of the Johannes Gutenberg University
of Mainz. This includes
measurements of the proton radius, meson form factor
measurements relevant for the hadronic contributions to the anomalous
magnetic moment of the muon, $(g-2)_\mu$, and searches for Dark Photons.
The work is carried out at the local high-intensity electron accelerator
MAMI (Mainz Microtron) as well as at the BES III experiment in Beijing.
Moreover, we also present future opportunities for precision physics at
the high-intensity electron accelerator MESA (Mainz Energy-recovering
Superconducting Accelerator),  which is currently under construction in
Mainz.
