  • After Report on Speed, a Rush of Scrutiny

    Once upon a time, the only thing that traveled faster than the speed of light was gossip. Thanks to the Internet, the whole physics world was watching on Friday when Dario Autiero, of the Institut de Physique Nucléaire de Lyon in France, in front of a palpably skeptical roomful of physicists, put a whole new…

    Measurement of the tt-bar Production Cross Section in pp Collisions at 7 TeV in Lepton + Jets Events Using b-quark Jet Identification

    Read the paper: TOP-11-003 The measured production rates of Top-antiTop pairs, where one lepton and four jets of particles is observed in the final state, show good agreement with Quantum Chromodynamics (QCD), the theory of the strong interaction.
