CF7 covers cosmic probes of fundamental physics topics beyond Dark Matter and Dark Energy. This includes measurements of neutrino properties from cosmology (overlap with NF 5), tests of general relativity, emergent spacetime (overlap with CF2,3,5), black hole information with gravitational waves, the tension between local distance ladder measurements and cosmic microwave background estimates of the Hubble constant, equation of state of dense nuclear matter and hadron-quark gluon phase transitions, gamma-ray and cosmic-ray physics, e.g. particle acceleration in astrophysical environments, bread-and-butter perturbative QCD and hadronic physics of extensive air showers, Lorentz Invariance Violation, search for evaporating primordial black holes and exotic particles such as SUSY q-balls and axions, and multi-messenger astrophysics.

We will have two initial town hall meetings:

1. Tuesday 21 July, 12:30-1:30 pm EDT (slides, notes, video recording)
2. Thursday 30 July, 2:00-3:00 pm EDT (slides, notes, video recording)
