Query: Axion-mediated electron-electron interaction in ytterbium monohydroxide
  molecule   The YbOH triatomic molecule can be efficiently used to measure the electron
electric dipole moment, which violates time-reversal (T) and spatial parity (P)
symmetries of fundamental interactions [I. Kozyryev, N.R. Hutzler, Phys. Rev.
Lett. 119, 133002 (2017)]. We study another mechanism of the T,P-violation in
the YbOH molecule - the electron-electron interaction mediated by the low-mass
axiolike particle. For this, we calculate the molecular constant that
characterizes this interaction and use it to estimate the expected magnitude of
the effect to be measured. It is shown that this molecular constant has the
same order of magnitude as the corresponding molecular constant corresponding
to the axion-mediated electron-nucleus interaction. According to our
estimation, an experiment on YbOH will allow one to set updated laboratory
constraints on the CP-violating electron-axion coupling constants.
