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.

TriInstitute Summer School on Elementary Particles 2018
39 talksCollection Number C18015The 2018 TriInstitute Summer School on Elementary Particles (TRISEP) will be held July 920 2018 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. For further information, please visit http:///.trisep.ca

Asymptotic Safety in a Dark Universe
17 talksCollection Number C18012The asymptotic safety paradigm is currently emerging as a highly promising idea for BeyondStandardModel 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 gravitymatter 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 longstanding 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 darkmattermodels. 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 1520 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 followup 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 latetime predictions in gravitational environments. Please note that this meeting is by invitation only.

Searching for New Particles with Black Hole Superradiance
11 talksCollection 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 tabletop fundamental physics
24 talksCollection 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 ongoing 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.
