Nuclear Physics / Physique nucléaire (DNP-DPN)

Invited Speaker / Conférencier invité

ALPHA is an international project at CERN, with substantial Canadian involvement, whose ultimate goal is to test symmetry between matter and antimatter via comparisons of the properties of atomic hydrogen with its antimatter counter-part, antihydrogen. After several years of development, we have recently achieved significant milestones, including the first stable confinement of...

709. High Precision Weak Charge Measurements using Parity Violating Electron Scattering: Looking for Signatures of New Physics at the Precision Frontier

Nuclear Physics / Physique nucléaire (DNP-DPN)

Invited Speaker / Conférencier invité

Measurements of the parity violating electron-proton and electron-electron asymmetries in the number of scattered electrons can be extremely sensitive probes for signatures of new physics beyond the standard model up to mass scales as high as $\mathrm{\Lambda }/g\simeq 7.5TeV$. The basic reason for this is that the measured asymmetry has a simple and, within the Standard Model (SM), precisely...

The anomalous magnetic moment of the muon, a_mu = (g_mu - 2)/2, has been measured to 0.54 ppm, and when compared to the Standard Model (SM) calculation of similar precision, a discrepancy of 3.6 sigma remains unexplained. This is perhaps a hint of new interactions beyond the SM, stimulating much theoretical interest and speculation. The muon g-2 experiment responsible for...

720. Investigation of the E2 and E3 matrix elements in ${}^{200}$Hg using direct nuclear reactions

Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)

A nuclear-structure campaign has been initiated to investigate the isotopes of Hg around mass 199. To date, ${}^{199}$Hg provides the most stringent limit on an atomic electric dipole moment (EDM)$$[1]. The observation of a permanent EDM would represent a clear signal of CP violation from new physics beyond the Standard Model. Theoretical nuclear-structure calculations for ${}^{199}$Hg are...
