Second test for chiral vacuum background (static) and Equivalence Principle parity violation (dynamic): Two differential scanning calorimeters (DSCs) are abutted and positioned so their sample pans are located along a north-south line. Each holds a ~3 mm diameter ~17 mg solid single crystal sphere of benzil, one in space group P3(1)21 (right-handed) and one in P3(2)21 (left-handed), mp = 95°C. In space groups P3(1)/P3(2) there are 1,2,4-thiadiazole-3,5-dicarbonitrile (mp = 67°C) or 2,2-bis(hydroxymethyl)propionic acid (mp = 190 °C). In all cases the paired crystals' atomic mass distributions are maximally parity divergent but their melts are achiral (not racemic!).
/_H(fusion) for both are simultaneously run. The procedure is run with new single crystals at half-hour intervals for 24 hours. If all /_/_H(fusion) are not zero, the experiment is repeated the next day with the calorimeters aligned east-west to confirm. Maximima and minima will be displaced by six hours (below).
Static insertion of crystal left and right shoes into a vacuum left foot occurs with different energies. When the shoes melt into achiral socks that static energy difference explicitly appears,
Earth's inertial spin acceleration and gravitational orbital acceleration (creating the signal in a composition Eotvos experiment) combine with paired-sample orientation to define a coordinate frame whose chirality cycles every 24 hours,
That presents a dynamic 24-hr sinusoidal net residual /_/_H(fusion) here. There might be seven Eotvos balances on Earth. Borrowing a pair of DSCs is easy. Either way, the signal maximizes at 45 degrees latitude and 04 July perihelion.
A parity-retaining Eotvos experiment detects mass(inertial), mass(gravitational) divergence. Maximum sensitivity is 5x10^(-14) difference/average. A parity-destroying calorimetry experiment outputs the net signal as (/_m)c^2 energy. Benzil's /_H(fusion) = 112 J/g. A 10^(-13) g/g parity anomaly is 8.99 joules. 5x10^(-14) difference/average is 4% of background in a DSC with SOP 0.1% precision. The slow and expensive experiment is no better than the fast and inexpensive one.
Now, the fun part. Intitiate the Big Bang with a strong chiral pseudoscalar vacuum background. Decay of this false vacuum powers cosmic inflation. It sources the parity-violating Weak interaction. Its chiral symmetry breaking allows selection of matter over antimatter. Its trace residual after cosmic inflation initiates contemporary biological homochirality. Being limited to the massed sector, 10^(-14) relative chiral vacuum background cannot be detected by EM vacuum refractive index, dispersion, or gyrotropy even over cosmic distances. It could be there without contradiction of any prior observation in any venue at any scale.
Somebody should look. A chemistry undergraduate summer project could earn a historic Nobel Prize/Physics, hence the desirability of performing a parity Eotvos experiment in a physics research group. The whole world knows how to grow and machine high quality quartz.
