摘要： The chirality-asymmetry macroscopic force mediated by light pseudoscalar particles between α -quartz and some achiral matter is studied. If this force between achiral source mass and α -quartz with some chirality is attractive, it will become repulsive when the chirality of the α -quartz crystal is changed. According to the tested limits of the coupling constant gs gp /\hbar c< 1.5× 10-24 at the Compton wavelength λ = 10-3 m, the force (F) between a 0.08× 0.08× 0.002 m3 block of α -quartz and a 0.08× 0.08× 0.01 m3 copper block with a separation being 0.5× 10-3 \mbox{m} in between, is estimated from the published data at less than 4.64× 10-24 N, i.e. F < 4.64× 10-24 N.

Abstract: The chirality-asymmetry macroscopic force mediated by light pseudoscalar particles between $\alpha $-quartz and some achiral matter is studied. If this force between achiral source mass and $\alpha $-quartz with some chirality  is attractive, it will become repulsive when the chirality of the $\alpha $-quartz crystal is changed. According to the tested limits of the coupling constant $g_{\rm s} g_{\rm p} / \hbar c < 1.5\times 10^{ - 24}$ at the Compton wavelength $\lambda = 10^{ - 3}$\,m, the force ($F$) between a $0.08\times 0.08\times 0.002$\,m$^{3}$ block of $\alpha $-quartz and a $0.08\times 0.08\times 0.01$\,m$^{3}$ copper block with a separation being  $0.5\times 10^{ - 3}\,\mbox{m}$ in between, is estimated from the published data at less than $4.64\times 10^{ - 24}\,\mbox{N}$, i.e. $F < 4.64\times 10^{ - 24}\,\mbox{N}$.
