Dynamics of $E_6$ Chiral Gauge Theories

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Andrew Goh, Hitoshi Murayama, Gup Singh, Bethany Suter, Jason Wong | Summary: We present exact non-perturbative solutions to chiral gauge theories based on the $E_6$ gauge group and several matter fermions in the fundamental $bf{27}$-dimensional representation. They are obtained when supersymmetric versions are perturbed by small supersymmetry […]

Dark Matter Velocity Distributions for Direct Detection: Astrophysical Uncertainties are Smaller Than They Appear

Kavli Affiliate: Lina Necib | First 5 Authors: Dylan Folsom, Carlos Blanco, Mariangela Lisanti, Lina Necib, Mark Vogelsberger | Summary: The sensitivity of direct detection experiments depends on the phase-space distribution of dark matter near the Sun, which can be modeled theoretically using cosmological hydrodynamical simulations of Milky Way-like galaxies. However, capturing the halo-to-halo variation […]
