We are pleased to announce that abstracts are now being accepted (oral and poster) for the 2021 CAP Virtual Congress which will be held from June 6-10, 2021 using the browser-based underline.io platform (no software installation required).

This Congress is an opportunity to showcase and celebrate the achievements of physicists in Canada and abroad.

Oral presentation abstracts submitted by the deadline of February 28th, 2021 are given priority consideration for programming.

Instructions for Creating Indico CERN Account:

We are again using the Indico abstract submission system hosted by CERN, which does not link with the existing CAP membership system nor the abstract submission system used before the 2014 Congress. Therefore, if you don’t already have an Indico CERN account, or didn’t set one up for last year’s Congress, you must create one before you can submit an abstract for the Congress.

To create a new account, follow these steps:

  1. Fill out the form on this page: https://account.cern.ch/account/Externals/RegisterAccount.aspx
  2. You will receive a verification e-mail. Click on the link in the e-mail to complete the process.
  3. Go to the Indico CAP2021 site (http://indico.cern.ch/e/CAP2021) and Click Login in the top right corner to access the CERN single sign-on page”.  Enter your account credentials and you will then be able to submit an abstract.
