      abstract     = {The production of $\pi ^{\pm }$, $\mathrm{K}^{\pm }$,
                      $\mathrm{K}^{0}_{S}$, $\mathrm{K}^{*}(892)^{0}$,
                      $\mathrm{p}$, $\phi (1020)$, $\Lambda $, $\Xi ^{-}$, $\Omega
                      ^{-}$, and their antiparticles was measured in inelastic
                      proton–proton (pp) collisions at a center-of-mass energy
                      of $\sqrt{s}$ = 13 TeV at midrapidity ($|y|<0.5$) as a
                      function of transverse momentum ($p_{\mathrm{T}}$) using the
                      ALICE detector at the CERN LHC. Furthermore, the
                      single-particle $p_{\mathrm{T}}$ distributions of
                      $\mathrm{K}^{0}_{S}$, $\Lambda $, and $\overline{\Lambda }$
                      in inelastic pp collisions at $\sqrt{s} = 7$ TeV are
                      reported here for the first time. The $p_{\mathrm{T}}$
                      distributions are studied at midrapidity within the
                      transverse momentum range $0\le p_{\mathrm{T}}\le 20$ GeV/c,
                      depending on the particle species. The $p_{\mathrm{T}}$
                      spectra, integrated yields, and particle yield ratios are
                      discussed as a function of collision energy and compared
                      with measurements at lower $\sqrt{s}$ and with results from
                      various general-purpose QCD-inspired Monte Carlo models. A
                      hardening of the spectra at high $p_{\mathrm{T}}$ with
                      increasing collision energy is observed, which is similar
                      for all particle species under study. The transverse mass
                      and $x_{\mathrm{T}}\equiv 2p_{\mathrm{T}}/\sqrt{s}$ scaling
                      properties of hadron production are also studied. As the
                      collision energy increases from $\sqrt{s}$ = 7–13 TeV,
                      the yields of non- and single-strange hadrons normalized to
                      the pion yields remain approximately constant as a function
                      of $\sqrt{s}$, while ratios for multi-strange hadrons
                      indicate enhancements. The $p_\mathrm{{T}}$-differential
                      cross sections of $\pi ^{\pm }$, $\mathrm {K}^{\pm }$ and
                      $\mathrm {p}$ ($\overline{\mathrm{p}}$) are compared with
                      next-to-leading order perturbative QCD calculations, which
                      are found to overestimate the cross sections for $\pi ^{\pm
                      }$ and $\mathrm{p}$ ($\overline{\mathrm{p}}$) at high
                      $p_\mathrm{{T}}$.},
