Collaboration Meeting May 31 - June 2, 2023

This will be the fourth meeting of the DarkLight @ ARIEL Collaboration.  It will be held May 31 - June 2, 2023 at TRIUMF in Vancouver, Canada.

The purpose of this meeting is to bring as many people as possible together to review:

• developments in dark matter searches,

• production of the DarkLight detector components,

• status and plans for the ARIEL accelerator,

• schedule for installing and commissioning the experiment, and

• plans for the first period of operation in the fall of 2023.

The search for a dark photon holds considerable interest in the physics community. Such a force carrier would begin to illuminate the dark sector. Many experiments have searched for such a particle, but so far it has proven elusive. In recent years the concept of a low mass dark photon has gained popularity in the physics community. Of particular recent interest is the ^8Be and ^4He anomaly, which could be explained by a 17 MeV mass dark photon. The proposed Darklight experiment would search for this potential low mass force carrier at ARIEL in the 10-20 MeV e^+e^- invariant mass range.
