Measurement of the Top Quark Pair Production Cross Section with
... We present a measurement of the top quark pair production cross section in e+jets and µ+jets events recorded with the CDF II detector. The data correspond to 1.12 fb−1 of pp collisions with center-of-mass energy 1.96 TeV taken during Run 2 of the Fermilab Tevatron. We identify tt candidate events by ...

Furthermore, the Higgs boson can be produced via the fusion of vector bosons which are predominantly radiated by interacting quarks and in association with a W or a Z boson. The decay of the Higgs boson in two W ...

DESY
The Deutsches Elektronen-Synchrotron (english German Electron Synchrotron) commonly referred to by the abbreviation DESY, is a national research center in Germany that operates particle accelerators used to investigate the structure of matter. It conducts a broad spectrum of inter-disciplinary scientific research in three main areas: particle and high energy physics; photon science; and the development, construction and operation of particle accelerators. Its name refers to its first project, an electron synchrotron. DESY is publicly financed by the Federal Republic of Germany, the States of Germany, and the German Research Foundation (DFG). DESY is a member of the Helmholtz Association and operates at sites in Hamburg and Zeuthen.
