Masahiro Morii is an experimental physicist working on studies of elementary particles and their interactions. He is currently involved in an experiment at Stanford Linear Accelerator Center, where a large number of neutral B mesons are produced by e+ e- collisions and are observed by the detector called BABAR. The experiment provides new insight into the origin of the CP violation, a phenomenon in which an apparently fundamental symmetry of space-time is not observed by the Nature. Prof. Morii has contributed to the construction of the BABAR detector and an upgrade of its trigger system. He leads the semileptonic-decay analysis working group, and seeks to determine the magnitude of the Cabibbo-Kobayashi-Maskawa matrix elements Vub and Vcb.

Prof. Morii is also involved in the preparation for the ATLAS experiment at the Large Hadron Collider at CERN. The experiment is anticipated to uncover the origin of the electroweak symmetry breaking, and has a great potential for discovering new physics beyond the Standard Model.
