Recent results on exclusive channels are reviewed. Inclusive spectral functions are the basis for QCD analyses, delivering an accurate determination of the strong coupling constant and quantitative information on nonperturbative contributions. Strange decays yield a determination of the strange quark mass. 1.

  • Prix Andr Lagarrigue 2010
    2010 André Lagarrigue Prize Under the sponsorship of the French Physical Society (SFP) and on the occasion of the 50th birthday of the Orsay Linear Accelerator Laboratory (LAL) in 2006, a prestigious Prize, awarded every second year, was created in honor of Professor André Lagarrigue. Director of LAL from 1969 until his untimely death in 1975. André Lagarrigue discovered, together with an European team, the weak interaction neutral currents in 1973, a crucial step in establishing the present theory of particle physics. The André Lagarrigue Prize rewards a senior physicist who has lead a large experimental project including conceptual design and realisation of a complex apparatus and has extracted the best of it with a strong team spirit and has carried out his work in a French laboratory or in close collaboration with French teams. This prize is co-financed by CEA, CERN, Ecole Polytechnique, IN2P3, LAL and the University Paris Sud 11. The international jury of the Andre Lagarrigue Prize1 met under the chairmanship of IN2P3 director Jacques Martino, and reviewed the nominees proposed by the French community of particles physics following a call for proposal sent to all French lab directors. The winner of the 2010 Andre Lagarrigue Prize is Michel Davier, Professor of Physics at the University Paris Sud 11 and a member of the French Academy of Science. Michel Davier's worldwide authority in the field of particle physics is undisputed and his prominent role is in every way worthy of that of André Lagarrigue. They share the same qualities of deep understanding of physics and of experimental devices of great complexity, of tenacity and pedagogy with the same passion for training young people.

  • Tau Leptons New Measurements of the Tau Mass
    Tau lineup. At this year's workshop on tau lepton physics, the second in the series, and hosted by Ohio State University, tau pioneer Martin Perl is seen with workshop chairman K.K. Gan (left) and Michel Davier, one of the chairmen of the first workshop, held in Orsay, France, in 1990. At the workshop it also emerged that a large amount of information on the scintillation properties of several materials and ions already has been compiled. In particular, cerium compounds can offer advantages when fast scintillation (some 20 ns) is needed. For ultrafast (nanosecond) scintillation, only crystals exhibiting special 'crossover' transitions can be considered, with the drawback of emitting in the vacuum UV. Similar expertise was gathered from exten­ sive work in solid state chemistry and crystalline defects. The Chamonix meeting was organ­ ized jointly by CERN, the French CNRS and the Italian INFN.

    lavi Training Activity net CONTRACT NO. 35482 01/10/2009 — 30/09/2010 We report on the fourth year Training and TOK activities of the Marie Curie Research and Training Network FLAVIAnet. The Training and TOK activities have been organized, supervised and coordinated among the several nodes by the FLAVIAnet Training Committee composed by M. Davier (Orsay), S. Descotes Genon (Orsay), P. Krizan (Ljubljana), P. Hernandez (Valencia), T. Mannel (Siegen), C. T. Sachrajda (Southampton) and chaired by N. Brambilla (Technical U. Munich). In the following we report the training and TOK achievements for each of the eleven FLAVIAnet nodes in the period 01/10/2009–30/09/2010. As it is detailed in the several sections of the report, for each node the training and transfer of knowledge program has been articulated at the following levels: • Individual training • Intra-Node Training • Inter-Node Training • Network Training The General Training Measures have been organized in: the Annual General Meeting held at the Technical University in Munich in September 2010 (and detailed in the FLAVIAnet Research Report), the Annual European Flavour Physics School and several Research Training Workshops (detailed in the FLAVIAnet Research Report). The annual Flavianet school took place in Bern, Switzerland, from June 21 to July 2, 2010. This year school was mainly aimed at PhD students and postdocs of the network, but was of course open to external participants. The number of students was 43, of which 18 from Bern, and we had 11 lecturers (for details see the report of Node 9). The school was organized as follows: 2 blocks of 2x45 min.

Bellaterra, 18. June 2019 Supervisor and tutor Author Dr Matthias Rudolf Jamin Dirk Hornung Abstract In this work, we perform a quantum chromodynamics (qcd) analysis on hadronic τ decays. We make use of the aleph data to fit the strong coupling and higher order operator product expansion (ope) contributions. Our approach is based on the qcd sum rules (qcdsr), especially the framework of fixed-order perturbation theory (fopt), which we apply for the vector + axial-vector (v+a) channel of the inclusive Cabibbo-allowed hadronic τ decay data. We perform fits using a new set of analytic weight functions to shed light on the discussion of the impor- tance of duality violation (dv).
