v 1 2 6 Ju n 20 01 Preprint INP MSU 2001 - 25 / 665 A Contribution of Photon Hadronic Component in the Leptoproduction Charmed Structure Function
We calculated the contribution of the photon hadronic component in the charmed structure function of the leptoproduction. The contribution comes from scattering of the c quarks of the virtual photon on the quarks and gluons of the proton. Comparison of our calculations with the measurements of the charm production in µ + p-scattering by EMC shows, that contribution of resolved photon can explai...
متن کاملMSGC test with fast neutrons
Results are presented from the exposure of a CMS performance prototype MSGC to a fast neutron beam having an average energy of 20 MeV and an intensity of 7 106 neutrons/mm2/s. A fluence equivalent to 3 years of LHC operation has been accumulated without damages to the detector. The stability of the MSGC operation in a heavily ionising particle flux is reported and the estimation of their produc...
متن کاملJa n 19 99 preprint INP 1816 / PH Subtracted Dispersion Relations for In - Medium Meson Correlators in QCD Sum Rules ⋆ Wojciech Florkowski and Wojciech Broniowski
We analyze subtracted dispersion relations for meson correlators at finite baryon density and temperature. Such relations are needed for QCD sum rules. We point out the importance of scattering terms, as well as finite, well-defined subtraction constants. Both are necessary for consistency, in particular for the equality of the longitudinal and transverse correlators in the limit of the vanishi...
متن کاملINP-MSU-96-41/448, UCR/96-25 Single top quarks at the Fermilab Tevatron
We present a calculation of the single top quark cross section for protonantiproton interactions with √ s = 1.8 TeV at the Fermilab Tevatron collider. We examine the effects of top mass, parton distribution functions, QCD scale, and collision energy, on each of the component production mechanisms, and study the kinematic distributions for standard model electroweak production. At the upgraded T...
متن کاملThe Citation Impact of Digital Preprint Archives for Solar Physics Papers†
Papers that are posted to a digital preprint archive are typically cited twice as often as papers that are not posted. This has been demonstrated for papers published in a wide variety of journals, and in many different subfields of astronomy. Most astronomers now use the arXiv.org server (astro-ph) to distribute preprints, but the solar physics community has an independent archive hosted at Mo...
