# Colliders and ghosts: Constraining inflation with the parity-odd galaxy four-point function

@article{Cabass2022CollidersAG, title={Colliders and ghosts: Constraining inflation with the parity-odd galaxy four-point function}, author={Giovanni Cabass and Mikhail M. Ivanov and Oliver H. E. Philcox}, journal={Physical Review D}, year={2022} }

Could new physics break the mirror symmetry of the Universe? Utilizing recent measurements of the parity-odd four-point correlation function of BOSS galaxies, we probe the physics of inflation by placing constraints on the amplitude of a number of parity-violating models. Within canonical models of (single-field, slow-roll) inflation, no parity-asymmetry can occur; however, it has recently been shown that breaking of the standard assumptions can lead to parity violation within the Effective…
