The 2027-2034 Vision for Nuclear Physics in Canada, with an outlook to 2041

The Canadian subatomic physics community establishes its scientific, and thus funding, priorities through periodic Long-Range Plans (LRP). The community is now putting together a new LRP, which will be in effect from 2027 through 2034, with its scope extending through 2041. As part of this process, the Canadian Institute of Nuclear Physics (CINP) has put together a strategic report, following an extensive consultation process. The report describes the broad and ambitious research program undertaken by the Canadian nuclear physics research community, both onshore and abroad, touching on key questions regarding the origin, evolution, and structure of visible matter in the universe. This document provides a grid of different Canadian nuclear physics projects undertaken now and in the future, and their associated timelines. It concludes with specific recommendations for maximizing Canadian scientific output in nuclear physics.

How to Do STEM Outreach Evaluation -- Recommendations Based on a Review of Self Evaluation Tools in Canadian STEM Outreach Programs

STEM (Science, Technology, Engineering, and Mathematics) outreach programs in Canada, especially those oriented towards youth, play a critical role in supporting the nation's future workforce, innovation capacity, and equity across social groups in STEM fields. They constitute a large, multi-layered ecosystem connecting universities, national laboratories, non profit organizations, and grassroots community groups. Despite the growing importance of these programs, and the frequency that they undergo self-evaluation, little systematic information exists on best practices or common approaches to evaluating the effectiveness of STEM outreach initiatives. To address this gap, we integrated literature review with email inquiries about self evaluation tools sent to Canadian STEM outreach programs funded by NSERC (Natural Sciences and Engineering Research Council of Canada) PromoScience grants. We contacted 200 programs and heard back from about 100 of them, for a response rate of 50%. Of those respondents, 68 shared information about a formal self-evaluation tool appropriate for general STEM outreach. The results led us to develop a toolbox of self-evaluation methods, master question banks and starting-point templates for student/participant and teacher/chaperone surveys, and a synthesized list of recommendations for evaluation process, design, and implementation. Our approach provides a broad treatment of how to do STEM outreach evaluation, supplementing the relevant literature, where large-N studies and Canadian studies are relatively rare. We acknowledge that some of the most effective practices in STEM outreach evaluation require resources or capacity (e.g. longitudinal approaches), which may be limited for many outreach practitioners, but others seem to have a high ratio of benefit to cost (e.g. adding qualitative questions to an otherwise quantitative survey).

Striving for Equity in Canadian Physics

We discuss a number of new initiatives and events since 2020 which we hope will contribute to advancement of equity issues within the physics community in Canada. A recent analysis of high-school data shows that men are still over-represented in high-school physics courses, and the fraction has not changed in over a decade. Results from a national survey show that despite improvements over the years, the percentage of women and gender diverse physicists drops by around 35% between undergraduate students to those in a physics career. This decline is even more notable among Black, Indigenous, and people of colour (BIPOC) women and gender diverse physicists, whose representation drops by almost 60%. Several programs from the National Sciences and Engineering Research Council (NSERC) have been implemented in order to improve equity, diversity, and accessibility in STEM on a national level, most notably the Chairs for Women in Sciences and Engineering (CSWE) and Chairs for Inclusion in Sciences and Engineering (CISE) initiatives. It is crucial to maintain data collection and support existing as well as new EDI projects in future years as we work to build a more inclusive community of physicists in Canada.

Higher order electroweak radiative corrections in lepton-proton scattering using covariant approach

We perform detailed calculations of electroweak radiative corrections to parity violating lepton scattering with a proton target up to quadratic and reducible two-loop level using a covariant approach. Our numerical results are presented at energies relevant for a variety of existing and proposed experimental programs such as Qweak, P2, MOLLER, MUSE, and experiments at the EIC. Analysis shows that such corrections at the Next-to-Next-to-Leading Order (NNLO) are quite significant and have to be included in searches of physics beyond the standard model, matching the increasing precision of the future experimental programs at low-energy scales.

Electroweak radiative corrections for polarized Moller scattering at future 11 GeV JLab experiment

We perform updated and detailed calculations of the complete NLO set of electroweak radiative corrections to parity violating e- e- --> e- e- (gamma) scattering asymmetries at energies relevant for the ultra-precise Moller experiment coming soon at JLab. Our numerical results are presented for a range of experimental cuts and relative importance of various contributions is analyzed. We also provide very compact expressions analytically free from non-physical parameters and show them to be valid for fast yet accurate estimations.
