  1. Isospin dependence of the Ar+Ni fusion-evaporation cross section

    … Pd nuclei, with mass number varying from 92 to 104. The measurements have been performed by the high performance 4pi detector INDRA, coupled with the magnetic spectrometer VAMOS. Even if the results are very preliminary, the obtained fusion-evaporation cross sections behaviour gives a hint at the …

  2. The Time-Of-Flight detector of ALICE at LHC: construction, test and commissioning with cosmic rays

    The Time-Of-Flight (TOF) detector of ALICE is designed to identify charged particles produced in Pb--Pb collisions at the LHC to address the physics of strongly-interacting matter and the Quark-Gluon Plasma (QGP). The detector is based on the Multigap Resistive Plate Chamber (MRPC) technology which …

  3. Pattern recognition analysis on heavy ion reaction data

    One of the problems in the analysis of nucleus-nucleus collisions is to get information on the value of the impact parameter b. This work consists in the application of pattern recognition techniques aimed at associating values of b to groups of events. To this end, a support vec- tor machine (SVM) …

  4. MEASUREMENT OF BRANCHING FRACTIONS OF B DECAYS TO K_1(1270) PI AND K_1(1400) PI AND DETERMINATION OF THE CKM ANGLE ALPHA FROM B0 --> A_1(1260)+/- PI-/+

    This dissertation reports the measurement of the branching fractions of neutral and charged B meson decays to final states containing a K_1(1270) or K_1(1400) meson and a charged pion. The data, collected with the BaBar detector at the SLAC National Accelerator Laboratory, correspond to 454 million …

  5. MISSING TRANSVERSE ENERGY MEASUREMENT IN ATLAS DETECTOR:FIRST LHC DATA RESULTS AND IMPORTANCE FOR PHYSICS STUDY

    The Large Hadron Collider (LHC) at CERN started its operation at the end of November 2009, first at a centre-of-mass energy of 900 GeV, then, since March 2010, at 7 TeV. During this period the ATLAS experiment has collected a large number of proton-proton collision events, resulting up to now in an …

  6. BETA DECAY STUDIES AS A TOOL TO INVESTIGATE NUCLEAR STRUCTURE IN THE N-RICH PO-FR REGION AND IN P-RICH CD ISOTOPES

    Beta decay is the most common form of radioactive decay, occurring in isotopes of all known elements along the nuclear chart. This makes it a formidable tool to probe the internal structure of nuclei both on the proton- and neutron-rich exotic nuclei, at the limit of the existence of the nucleus. …
