Abstract
Measurements of the total and differential cross sections and for mesons produced in collisions at are presented. The data correspond to an integrated luminosity of collected by the CMS experiment operating at the LHC. The exclusive decay , with , is used to detect mesons and to measure the production cross section as a function of and . The total cross section for and is measured to be , where the first uncertainty is statistical, the second is systematic, and the last is from the luminosity measurement.
