| Popis: | International audience; We have searched for a short-range spin-dependent interaction using the spin relaxation of hyperpolarized 33^3He. Such a new interaction would be mediated by a hypothetical light scalar boson with \CP-violating couplings to the neutron. The walls of the 33^3He cell would generate a pseudomagnetic field and induce an extra depolarization channel. We did not see any anomalous spin relaxation and we report the limit for interaction ranges λλ\lambda between 111 and 100 μm100 μm100~\rm{\mu m}: gsgpλ2≤2.6×10−28 m2(95 %C.L.)gsgpλ2≤2.6×10−28 m2(95 %C.L.)g_sg_p \lambda ^2 \leq 2.6\times 10^{-28}~\mathrm{m^2}\, ( 95~\%\, \mathrm{C.L.}), where gsgsg_s(gpgpg_p) are the (pseudo)scalar coupling constant, improving the previous best limit by 1 order of magnitude. |
