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.

Asymptotic Safety in a Dark Universe
17 talks-Collection Number C18012The asymptotic safety paradigm is currently emerging as a highly promising idea for Beyond-Standard-Model physics with key progress in asymptotically safe quantum gravity and asymptotically safe matter models. The last years have seen not only the development of asymptotically safe gravity-matter models but also the discovery of asymptotically safe beyond Standard Model matter models that are under control in perturbation theory. New exciting avenues in (astro) particle physics are now waiting to be explored. For example although the nature of dark matter is a long-standing riddle it is a fact that experimental searches have so far not provided any direct clues but have instead come up with ever more stringent constraints on theoretically preferred regions of parameter space for dark-matter-models. Thus the key to unraveling this riddle could be a new theoretical paradigm to guide model builders. This workshop aims at exploring whether asymptotic safety can be a candidate for this new paradigm. We aim to bring together experts on phenomenological models and quantum gravity to probe both the theoretical viability and empirical signatures of asymptotically safe extensions of the standard model that include gravity. To facilitate a highly productive meeting that can trigger new collaborations each talk will be followed up by 15-20 minutes discussion time. Further each day of the workshop will feature a dedicated discussion session. Participants will be encouraged to contribute questions for the discussion both before as well as during the workshop. The last day of the workshop will conclude with a roadmap discussion during which all participants will be given the opportunity to propose concrete suggestions for follow-up work that might lead into future joint projects.

Open EFT's and Gravity as a Medium
-Collection Number C18032This event is meant to study the connections between quantum fields in curved spacetimes with horizons and the effective field theory methods as applied to open systems (Open EFTs). In particular the hope is to exploit the existence of tools (from areas like optics) for dealing with hierarchies of scale in open systems and adapt the to see if they can inform our understanding of controlling late-time predictions in gravitational environments. Please note that this meeting is by invitation only.

Searching for New Particles with Black Hole Superradiance
11 talks-Collection Number C18010Black hole superradiance is a fascinating process in general relativity and a unique window on ultralight particles beyond the standard model. Bosons -- such as axions and dark photons -- with Compton wavelengths comparable to size of astrophysical black holes grow exponentially to form large clouds spinning down the black hole in the process and produce monochromatic continuous gravitational wave radiation. In the era of gravitational wave astronomy and increasingly sensitive observations of astrophysical black holes and their properties superradiance of new light particles is a promising avenue to search for new physics in regimes inaccessible to terrestrial experiments. This workshop will bring together theorists data analysts and observers in particle physics gravitational wave astronomy strong gravity and high energy astrophysics to explore the signatures of black hole superradiance and to study the current and future possibilities of searching for new particles with black holes.

Experimental techniques in table-top fundamental physics
24 talks-Collection Number C17030In the last few years there has been a resurgence of interest in small scale high sensitivity experiments that look for new forces and new particles beyond the Standard Model. They promise to expand our understanding of the Cosmos and possibly explain mysteries such as Dark matter in a way that is complementary to colliders and other large scale experiments. There is a number of different physics motivations and approaches currently being explored in many on-going and newly proposed experiments and they often share common experimental techniques.Many workshops in this field focus on the theory motivations behind these experiments without emphasis on the details of the experimental techniques that enable precision measurements. There is also substantial experimental expertise across many fields, often outside of fundamental physics community, that can be relevant to ongoing and proposed experiments.Thus, we decided to organize the workshop around some of the common experimental techniques. We hope it will be educational for both experimentalists and theorists and lead to discussions on the best way forward. We would like to bring together experimentalists with different expertise in the hope that it will lead to new ideas through interdisciplinary interactions. For theorists, we expect it to provide better appreciation of the challenges and opportunities in improving the sensitivity of precision measurement experiments.

New Directions in Dark Matter and Neutrino Physics
28 talks-Collection Number C17026Continuing investment in fundamental weakly-coupled science, primarily through neutrino experiments and dark matter searches, prompts the question: is the maximum possible scientific information going to be extracted from these experiments? Are there new creative uses of the existing and planned facilities that would advance our knowledge of fundamental physics? Are there physics targets that have been overlooked by the current approach? This workshop will attempt to advance discussion of these topics, and concentrate on non-traditional ideas and alternative methods of probing new physics, both at underground laboratories and at high-intensity accelerators. The workshop aims to complement the large international conference, Topics in Astroparticle and Underground Physics 2017, to be held in Sudbury ON July 24-28, by directly preceding that meeting.

CMB birefringence from axion strings
Andrew Long Rice University
A cosmological network of axion strings in our Universe today may leave its imprint on the polarization pattern of the cosmic microwave background radiation through the phenomenon of axion-string-induced birefringence. I will explain how this signal arises, discuss how it depends on the properties of the string network and the axion-photon coupling, describe how existing measurements of anisotropic birefringence place constraints on axion strings, and discuss how the non-Gaussian nature of this signal could be leveraged in searches with future data.
