Query: Magnetic reconnection as a mechanism to produce multiple
  protonpopulations and beams locally in the solar wind   Context. Spacecraft observations early revealed frequent multiple proton
populations in the solar wind. Decades of research on their origin have focused
on processes such as magnetic reconnection in the low corona and wave-particle
interactions in the corona and locally in the solar wind.Aims.This study aims
to highlight that multiple proton populations and beams are also produced by
magnetic reconnection occurring locally in the solar wind. Methods. We use high
resolution Solar Orbiter proton velocity distribution function measurements,
complemented by electron and magnetic field data, to analyze the association of
multiple proton populations and beams with magnetic reconnection during a
period of slow Alfv\'enic solar wind on 16 July 2020. Results. At least 6
reconnecting current sheets with associated multiple proton populations and
beams, including a case of magnetic reconnection at a switchback boundary, are
found during this day. This represents 2% of the measured distribution
functions. We discuss how this proportion may be underestimated, and how it may
depend on solar wind type and distance from the Sun. Conclusions. Although
suggesting a likely small contribution, but which remains to be quantitatively
assessed, Solar Orbiter observations show that magnetic reconnection must be
considered as one of the mechanisms that produce multiple proton populations
and beams locally in the solar wind.
