    “…It reveals an excess in the dijet mass range 150 GeV/c^2, 4.1\sigma beyond SM expectations. We show that in the context of low-mass string theory this excess can be associated with the production and decay of a leptophobic Z', a singlet partner of SU(3) gluons coupled primarily to baryon number. …”

    “…Two complementary characterisation techniques are discussed: the first uses a custom built telescope and a 120GeV pion beam from the Super Proton Synchrotron (SPS) at CERN; the second employs a novel technique to illuminate the sensor with a micro-focused synchrotron X-ray beam at the Diamond Light Source, UK. …”

    “…During the data taking period from 2009 until 2011, the ATLAS TDAQ system has been used very successfully to collect proton-proton data at LHC centre-of-mass energies between 900 GeV and 7 TeV. The TDAQ system is mostly made of off-the-shelf processing units organized in a farm of 2000 elements. …”

    “…The TRT is made of 300000 straw-tubes providing on average 30 two-dimensional space points with ~130 µm resolution for charged particle tracks with |η| < 2 and pT > 0.5 GeV. Along with continuous tracking, the TRT provides electron identification capability through the detection of transition radiation X-ray photons. …”

    “…The European accelerator neutrino community submitted end of July 2012 to the European Strategy in Particle Physics (ESPP) 2012 Symposium its proposal of the next global accelerator neutrino () facility for Europe to build or help build (NEu2012 D3.3.1): a new giant European underground home for mega  detectors in Finland 2300 Km from CERN, served by MW CERN  beams, ultimately a 10 GeV Neutrino Factory. Early in 2013, NEu2012 D3.2.1 documented further the analysis of performance and physics potential of upgrades and/or of major additions to existing neutrino facilities as evaluated in the NEu2012 years. …”

The 160 GeV =c polarized muon beam of CERN’s M2 beamline allows the COMPASS ex- periment to investigate spin effects using polarized solid-state targets. …”

    “…Measuring the transverse beam size in the Large Hadron Collider by using Ionization Profile Monitors is a difficult task for energies above injection during the energy ramp from 450 GeV to 6.5TeV. The beam size decreases from around 1mm to 200um and the brightness of the beam is high enough to destroy the structure of any form of interacting matter. …”

    “…This implies the need for matching both schemes at an intermediate switching scale, $L_{\rm swi}$, which we choose roughly in the range 2-4 GeV. In this contribution we present a preliminary result for this matching procedure, and we then focus on our almost final results for the scale evolution of the SF coupling from $L_{\rm swi}$ towards the perturbative regime, where we extract the $N_{\rm f} = 3$ ${\Lambda}$-parameter, ${\Lambda}_{\overline{\rm MS}}^{N_{\rm f}=3}$, in units of $L_{\rm swi}$ . …”
