Charge dependent azimuthal correlations in Pb--Pb collisions at sNN=2.76\sqrt{s_{NN}} = 2.76 TeV

Separation of charges along the extreme magnetic field created in non-central relativistic heavy--ion collisions is predicted to be a signature of local parity violation in strong interactions. We report on results for charge dependent two particle azimuthal correlations with respect to the reaction plane for Pb--Pb collisions at $\sqrt{s_{NN}} = 2.76$ TeV recorded in 2010 with ALICE at the LHC. The results are compared with measurements at RHIC energies and against currently available model predictions for LHC. Systematic studies of possible background effects including comparison with conventional (parity-even) correlations simulated with Monte Carlo event generators of heavy--ion collisions are also presented.Comment: Published in the proceedings of "Quark Matter 2011", Annecy-Franc

Сравнительные результаты хирургического и комбинированного лечения больных раком пищевода

Резюме. Представлены непосредственные и отдаленные результаты лечения 167 больных раком пищевода. Комбинированное лечение с использованием предоперационной гамма-терапии крупными фракциями было проведено 95 пациентам, хирургическое — 72. Отмечено, что предоперационное облучение не сопровождалось увеличением частоты послеоперационных осложнений, но и не способствовало улучшению отдаленных результатов операций. Ключевые слова: рак пищевода, комбинированное лечение, хирургическое лечение.Summary. Immediate and remote results of the treatment of 167 patients with esophagus cancer are reported. Combined treatment with pre-surgery large-fraction gamma-therapy was applied in 95 patients; 72 patients were operated without pre-surgery radiation treatment. Pre-surgery irradiation is shown to cause no increase in the frequency of post-operation complications. At the same time, it failed to improve the remote results of surgery. Key Words: esophagus cancer, combined treatment, surgery

The Charge Form Factor of the Neutron from the Reaction \pol{2H}(\pol{e},e'n)p

We report on the first measurement of spin-correlation parameters in quasifree electron scattering from vector-polarized deuterium. Polarized electrons were injected into an electron storage ring at a beam energy of 720~MeV. A Siberian snake was employed to preserve longitudinal polarization at the interaction point. Vector-polarized deuterium was produced by an atomic beam source and injected into an open-ended cylindrical cell, internal to the electron storage ring. The spin correlation parameter A^V_{ed} was measured for the reaction \pol{2H}(\pol{e},e'n)p at a four-momentum transfer squared of 0.21 (GeV/c)^2 from which a value for the charge form factor of the neutron was extracted.Comment: 4 pages, 5 file

ANTARES: the first undersea neutrino telescope

The ANTARES Neutrino Telescope was completed in May 2008 and is the first operational Neutrino Telescope in the Mediterranean Sea. The main purpose of the detector is to perform neutrino astronomy and the apparatus also offers facilities for marine and Earth sciences. This paper describes the design, the construction and the installation of the telescope in the deep sea, offshore from Toulon in France. An illustration of the detector performance is given

Experience with the silicon strip detector of ALICE

The Silicon Strip Detector (SSD) forms the two outermost layers of the ALICE Inner Track- ing System (ITS), connecting the TPC with the inner layers of the ITS. The SSD consists of 1698 double-sided silicon microstrip modules, 95 μm pitch, distributed in two cylindrical bar- rels, whose radii are 38 cm and 43 cm, respectively. With 4.8 square meters it is today’s largest installed double-sided strip detector. The design and construction will be discussed, both in view of the requirements of a decade ago and in the light of today’s achieved performance. Like the other LHC detectors, the SSD is waiting for beam after extensive commissioning with cosmics. These commissioning results will be presented. Cosmics data without magnetic field were used for alignment and for relative gain calibration. Together with the measured noise this allowed the signal-to-noise ratio to be determined as well as the charge matching quality. Cosmics data collected with magnetic field were used for energy-loss calibratio
