Abstract
Using three- and four-body decays of D mesons produced in semileptonic b-hadron decays, precision measurements of D meson mass differences are made together with a measurement of the D (0) mass. The measurements are based on a dataset corresponding to an integrated luminosity of 1.0 fb(−1) collected in pp collisions at 7 TeV. Using the decay D (0) → K (+) K (−) K (−) π (+), the D (0) mass is measured to beFile in questo prodotto:
