Particles vs. New Probes (P vs. NP)
Over the past several decades, the search for physics beyond the Standard Model has transformed into an expansive and collaborative effort. In particular, astrophysical and cosmological probes have seen significant advancements in observational capabilities and theoretical precision, greatly refining our understanding and narrowing our search space. The upcoming two decades promise similar order-of-magnitude gains in sensitivity, and it is essential that we prepare now by strengthening interdisciplinary connections and aligning our efforts to meet the challenges and opportunities that lie ahead.
This workshop is designed to catalyze interdisciplinary initiatives between particle theorists and astrophysicists, focusing on areas well-represented by the domain knowledge at the Center for Computational Astrophysics (CCA). We will convene experts working on new physics that modify standard paradigms in cosmology, galaxy formation, gravitational waves, plasma physics, stellar physics, and compact objects, alongside specialists in these fields.
Through a series of focused talks and extended discussions, this workshop aims to foster new, long-term collaborations between these two communities, driving forward our understanding of the universe and opening up new avenues for discovery.

Title: Testing Gravity at Ever Shorter Scale: A Trip into Exotic Experimental Physics
Abstract: Since the times of Henry Cavendish and John Mitchell, the strength of gravity has been measured by comparing it to the reaction of a calibrated mechanical spring. While in the last 60 years planetary measurements (with natural and artificial bodies) have provided remarkable accuracy at large distance, measurements in the lab have continued to rely various incarnations of the good old mechanical springs, in many cases resulting in superb experiments and results. In this talk, I will explore a number of drastically different techniques recently developed specifically to tackle the short distance regime, where many theories suggest something exotic may be happening. This will be a trip into AMO and high resolution nuclear spectroscopy. While science results are gradually appearing, I hope to convince the audience that, as is often the case with new techniques, a new and exciting array of questions and applications are also emerging! -

- We are located at 160/162 5th Avenue. The entrance to our buildings are on 21st Street.
- All attendees must check-in with security in the lobby each day before proceeding to the event location. You will need a government issued photo ID to gain entry into all buildings. Please allot extra time to check-in with security.
- An event badge will be given to you on day one which should reduce the amount of time needed to check-in. If you lose your badge, you can request a new one through event admin.
- All participants must clear the event floor at the end of each day to allow for a cleaning crew and facilities team to come in and reset the space.
- Anyone who wishes to stay at Flatiron Institute may do so if accompanied by a Flatiron Institute employee. If you remain onsite, you must move the 5th, 6th floors (CCA), or the 11th floor dining area of 162 Fifth Ave.

COVID Protocols
-
- Individuals are welcome to continue masking in any setting at any time if they so choose. Please respect your colleagues’ choices as to where and when they wish to mask.
- Anyone experiencing symptoms consistent with COVID-19 should remain away from the offices and test (rapid or PCR) at the earliest opportunity.
- Consistent with current CDC guidance, anyone testing positive will be required to isolate away from the offices for at least 5 full days, returning once symptoms (if any) have fully resolved and the person is testing negative via rapid test.
- All positive cases should be reported to the event host and/or administrative staff.
