Particle physics is the science which identifies nature's constituents and interactions at the most fundamental level, with an emphasis on comparing theoretical ideas with both terrestrial experiments and astrophysical observations. This mandate gives it a strong overlap with string theory, quantum gravity and cosmology. Particle physicists at Perimeter Institute are currently involved in identifying how cosmological observations and terrestrial accelerator and underground experiments constrain the theoretical possibilities for physics beyond the Standard Model.

TRISEP 2023
39 talksCollection NumberC23020Talks are recorded and posted on PIRSA (within approx 24 hours).
The 2023 TriInstitute Summer School on Elementary Particles (TRISEP) will be held June 1930, 2023 in Perimeter Institute for Theoretical Physics, Waterloo, ON, Canada.
TRISEP is an international summer school organized jointly by the Perimeter Institute for Theoretical Physics, SNOLAB, and TRIUMF Canada's laboratory for particle and nuclear physics. TRISEP will feature lectures by leading experts in the field of particle physics in its broadest sense and is designed to be very interactive with ample time for questions, discussions and interaction with the speakers. The school is intended for graduate students of all levels who were already exposed to quantum field theory.Registration for in person attendance to TRISEP is now open. Anyone requiring financial assistance to attend must apply by May 19. Requests for financial assistance are vetted on a casebycase basis and application for funding is not guaranteed.
Previous TRISEP Schools:
2022, 2021, 2019, 2018, 2017, 2016, 2015, 2014 and 2013.
Territorial Land AcknowledgementPerimeter Institute acknowledges that it is situated on the traditional territory of the Anishinaabe, Haudenosaunee, and Neutral peoples.
Perimeter Institute is located on the Haldimand Tract. After the American Revolution, the tract was granted by the British to the Six Nations of the Grand River and the Mississaugas of the Credit First Nation as compensation for their role in the war and for the loss of their traditional lands in upstate New York. Of the 950,000 acres granted to the Haudenosaunee, less than 5 percent remains Six Nations land. Only 6,100 acres remain Mississaugas of the Credit land.
We thank the Anishinaabe, Haudenosaunee, and Neutral peoples for hosting us on their land.

Quantum Simulators of Fundamental Physics
23 talksCollection NumberC23019This meeting will bring together researchers from the quantum technology, atomic physics, and fundamental physics communities to discuss how quantum simulation can be used to gain new insight into the physics of black holes and the early Universe. The core program of the workshop is intended to deepen collaboration between the UKbased Quantum Simulators for Fundamental Physics (QSimFP; https://www.qsimfp.org) consortium and researchers at Perimeter Institute and neighbouring institutions. The weeklong conference will consist of broadlyaccessible talks on work within the consortium and work within the broader community of researchers interested in quantum simulation, as well as a poster session and ample time for discussion and collaboration

School on TableTop Experiments for Fundamental Physics
27 talksCollection NumberC22030This School aims at bringing together graduate students and junior postdocs, both theorists and experimentalists, who are interested in proposing and realizing new tabletop experiments to test fundamental physics. The goal is to allow them to interact and learn from each other, forming a community.
The School will consist of some theoretical lectures for experimentalists, and experimental lectures for theorists. The scope is to offer basic and relevant notions of each field to physicists with a different background, in order to fill some of the gaps of the respective academic curricula.
The theoretical lectures will cover a review of the Standard Model with emphasis on precision tests, such as the search of new longrange forces and of electrical dipole moments. Another main topic will be a focused introduction on Dark Matter, looking at its cosmological production mechanisms, its impact on astrophysics and cosmology, and its laboratory detection.
On the experimental side, the School will cover a range of techniques for probing weak electromagnetic fields, short distance forces, single photons, fundamental electric dipole moments, as well as atom interferometers and optomechanical sensors.Territorial Land Acknowledgement

Octonions and the Standard Model
16 talksCollection NumberC21001Over the years, various researchers have suggested connections between the octonions and the standard model of particle physics. The past few years, in particular, have been marked by an upsurge of activity on this subject, stimulated by the recent observation that the standard model gauge group and fermion representation can be elegantly characterized in terms of the octonions. This workshop, which will be the first ever on this topic, is intended to bring this new community together in an attempt to better understand these ideas, establish a common language, and stimulate further progress.
The workshop will consist of an hourlong talk every Monday at noon (EST), with the first talk on Monday February 8, and the final talk on Monday May 17.

17 talksCollection NumberC19044This crossdisciplinary workshop gathers theorists who have been working on novel approaches to understanding the structure of the Standard Model and its link to cosmology and gravity. It follows the previous Simplicity I and II workshops at Princeton University (2014) and Fermilab (2016) and will be a small informal meeting with plenty of room for discussions.
