The particle spectra of parity-violating theories: A less radical approach and an upgrade of PSALTer
Will Barker, Georgios K. Karananas, Haochen Tu
Due to computational barriers, the effects of parity violation have so far been grossly neglected in gravitational model-building, leading to a serious gap in the space of prior mo…
