Abstract

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 0K + K K π +, the D 0 mass is measured to be $ M\left( {{D^0}} \right)={{{1864.75\pm 0.15\left( {\mathrm{stat}} \right)\pm 0.11\left( {\mathrm{syst}} \right)\mathrm{MeV}}} \left/ {{{c^2}}} \right.}. $ The mass differences $ \begin{array}{*{20}{c}} {{{{M\left( {{D^{+}}} \right)-M\left( {{D^0}} \right)=4.76\pm 0.12\left( {\mathrm{stat}} \right)\pm 0.07\left( {\mathrm{syst}} \right)\mathrm{MeV}}} \left/ {{{c^2}}} \right.},} \hfill \\ {{{{M\left( {{D^s}} \right)-M\left( {{D^{+}}} \right)=98.68\pm 0.03\left( {\mathrm{stat}} \right)\pm 0.04\left( {\mathrm{syst}} \right)\mathrm{MeV}}} \left/ {{{c^2}}} \right.}} \hfill \\ \end{array} $ are measured using the D 0K + K π + π and $ D_{(s)}^{+}\to {K^{+}}{K^{-}}{\pi^{+}} $ modes.
