\[Sec:Intro\]Introduction
=========================

It is rightly beyond doubt that the laws of physics violate parity. The elegant experiments of the 1950s [@Wu:1957my; @Garwin:1957hc; @PhysRev.109.1015] unambiguously showed that the weak interaction of the Standard Model can tell the difference between our universe and its mirror image. However, no attempts have yet been made to identify whether there are non-standard parity violation mechanisms which operate only at high energies probed by the Large Hadron Collider (LHC).

The absence of tests of parity is largely a pragmatic response to the obstacles presented by the LHC: its beams are not polarised, its detectors are not sensitive to polarizations, and it is mathematically impossible to construct a parity violating spin-averaged matrix element within any $CP$-conserving Locally Lorentz-Invariant quantum field theory (LLIQFT), effective or otherwise.[^1] Given that the only route to probing parity-violation in the Standard Model at the LHC would be from within the $C$-even part of its (very small) $CP$-violating sector,[^2] it is not surprising that no such analyses have yet been performed.[^3]
