      abstract     = {Production of prompt J/ψ meson pairs in proton-proton
                      collisions at $ \sqrt{s} $ = 7 TeV is measured with the CMS
                      experiment at the LHC in a data sample corresponding to an
                      integrated luminosity of about 4.7 fb$^{−1}$. The two J/ψ
                      mesons are fully reconstructed via their decays into
                      μ$^{+}$ μ$^{−}$ pairs. This observation provides for the
                      first time access to the high-transverse-momentum region of
                      J/ψ pair production where model predictions are not yet
                      established. The total and differential cross sections are
                      measured in a phase space defined by the individual J/ψ
                      transverse momentum (p$_{T}^{J/}^{ψ}$) and rapidity
                      (|y$^{J/}^{ψ}$ |): |y$^{J/}^{ψ}$ | < 1.2 for
                      p$_{T}^{J/}^{ψ}$ > 6.5 GeV/c, 1.2 < |y$^{J/}^{ψ}$ | < 1.43
                      for a p$_{T}$ threshold that scales linearly with
                      |y$^{J/}^{ψ}$ | from 6.5 to 4.5 GeV/c, and 1.43 <
                      |y$^{J/}^{ψ}$ | < 2.2 for p$_{T}^{J/}^{ψ}$ > 4.5 GeV/c.
                      The total cross section, assuming unpolarized prompt J/ψ
                      pair production is 1.49 ± 0.07 (stat) ±0.13 (syst) nb.
                      Different assumptions about the J/ψ polarization imply
                      modifications to the cross section ranging from −31\% to
                      +27\%.},
