Abstract
Measurements of the differential production cross sections and for mesons produced in collisions at are presented. The data set used was collected by the CMS experiment at the LHC and corresponds to an integrated luminosity of . The production cross section is measured from meson decays reconstructed in the exclusive final state , with the subsequent decays and . The total cross section for and is measured to be , where the first uncertainty is statistical and the second is systematic.
