High Energy Physics Seminar

A major goal of modern particle physics is to search for phenomena
that are in conflict with our best theoretical understanding of
nature, the Standard Model (SM). The Magnetic Dipole Moment of an
electron and positron (so-called g-factor) is the most precise
prediction of the SM and has been measured with a relative precision
of 10^{-13}. Beyond the recent g-factor measurement, quantum control
and entanglement of trapped electrons and positrons, as well as their
contribution to the precision measurements, will be discussed.

The nuclear Schiff Moment (NSM) serves as a sensitive probe of
CP-violating physics Beyond the SM, similar to the electron electric
dipole moment (eEDM). The signal is enhanced in octupole-deformed
nuclei, such as Francium-223, Radium-225, and Thorium-227. Quantum
control of molecules containing these nuclei allows a sensitive search
for beyond-SM physics. I will present our plan to search for new
physics using 227ThF+.

The talk is in 469 Lauritsen.
