11. Theory of dark photons and dark sectors

David McKeen (TRIUMF)

7/18/18, 3:30 PM

I will review dark sectors—a generic name for new, light particles that couple weakly to the standard model—with a focus on dark photons. Dark sectors have received a large amount of attention in recent years as explanations of a number of experimental anomalies and as the source of the Universe's dark matter, required by astronomical and cosmological observations. I will discuss future...

12. Opportunities for Dark Sector Searches with ARIEL

Luca Doria (JGU Mainz)

7/18/18, 4:00 PM

The availability of a high-current electron accelerator at TRIUMF opens novel avenues for dark sector experiments. In particular, fixed-target experiments represent an excellent opportunity for testing dark sector scenarios with high sensitivity. After reviewing some existing experimental proposals, sensitivity calculations for an experiment at TRIUMF taking advantage of the ARIEL beam will...

13. TRIUMF e-linac production of weakly-coupled MeV-mass particles

John Behr (TRIUMF)

7/18/18, 4:30 PM

I will discuss backgrounds and possible scenarios using TRIUMF's existing e-linac to produce and detect MeV-mass particles, assuming the previous talks and somewhat dated PPAC submission (daqshare.triumf.ca/~trinat/darkPPAC.pdf). The recent improved measurement of the fine-structure constant predicts a different electron g-2 compared to experiment, motivating...

14. From Nano Materials to Giant Resonances - ARIEL Target Ion Source Opportunities

Dr Alexander Gottberg (TRIUMF)

7/18/18, 5:00 PM

ARIEL will dramatically increase the availability of radioactive ion beams by harvesting isotopes from three target stations simultaneously - a worldwide unprecedented technology - enhancing the scientific output of the laboratory. For the first time, high-power electrons (up to 500 kW) will be converted into gamma rays inducing photonuclear reactions in one target, while two others are being...
