      abstract     = {This Letter presents the first experimental evidence of the
                      attractive strong interaction between a proton and a ϕ
                      meson. The result is obtained from two-particle correlations
                      of combined $p$-ϕ⊕ $\bar{p}$-ϕ pairs measured in
                      high-multiplicity pp collisions at $\sqrt{s}$ = 13 TeV by
                      the ALICE Collaboration. The spin-averaged scattering length
                      and effective range of the p-ϕ interaction are extracted
                      from the fully corrected correlation function employing the
                      Lednický-Lyuboshits approach. In particular, the imaginary
                      part of the scattering length vanishes within uncertainties,
                      indicating that inelastic processes do not play a prominent
                      role for the p-ϕ interaction. These data demonstrate that
                      the interaction is dominated by elastic p-ϕ scattering.
                      Furthermore, an analysis employing phenomenological
                      Gaussian- and Yukawa-type potentials is conducted. Under the
                      assumption of the latter, the N-ϕ coupling constant is
                      found to be $g_{N-ϕ}$ = 0.14 ± 0.03(stat) ± 0.02(syst).
                      This work provides valuable experimental input to accomplish
                      a self-consistent description of the N-ϕ interaction, which
                      is particularly relevant for the more fundamental studies on
                      partial restoration of chiral symmetry in nuclear medium.},
