Outline of Final Research Achievements

(1) I have developed the "Weight function method," which enables precise measurements of particle properties in high energy experiments, towards practical applications in the LHC experiments. In collaboration with experimentalists I performed detailed analyses necessary for top mass precise determination using this method. (2) I showed that in principle mt can be measured with about 30 MeV accuracy in future linear collider experiments, by incorporating recent theoretical developments in higher-order corrections. (3) Applying the same method, I determined the MSbar masses of the charm and bottom quarks. The determined values were adopted as the most recent determinations in the 2016 edition of the Particle Data Group (PDG). (4) I was appointed as the encoder of the top quark session in PDG, and have been compiling the newest data on top quark properties.
