Design of the Palmer Pickup for Stochastic Pre-Cooling of Hot Rare Isotopes at the CR / Barker, D J (Darmstadt, GSI) ; Dimopoulou, C (Darmstadt, GSI) ; Peschke, C (Darmstadt, GSI) ; Thorndahl, L (CERN)
We report on the design of a Faltin type pickup for the stochastic pre-cooling of rare isotope beams at 740 MeV/u, using a bandwidth of 1-2 GHz, for the Collector Ring (CR) in the FAIR project at GSI. The design difficulties inherent in Faltin rails at these frequencies are described. [...]

ISOLTRAP's multi-reflection time-of-flight mass separator/spectrometer / Wolf, R N ; Wienholtz, F ; Atanasov, D ; Beck, D ; Blaum, K ; Borgmann, Ch ; Herfurth, F ; Kowalska, M (CERN) ; Kreim, S ; Litvinov, Yu A et al.
The online precision mass spectrometer ISOLTRAP at ISOLDE/CERN was recently upgraded by adding a multi-reflection time-of-flight mass separator/spectrometer (MR-ToF MS) between the linear radio-frequency ion trap and the two Penning traps already in place. As a mass separator, the MR-ToF device has improved significantly ISOLTRAP's capability of purification of contaminated ion beams. [...]

Numerical simulations of energy deposition caused by 50 MeV—50 TeV proton beams in copper and graphite targets / Nie, Y (CERN) ; Schmidt, R (CERN) ; Chetvertkova, V (GSI Helmholtzzentrum für Schwerionenforschung) ; Rosell-Tarrago, G (University of Barcelona) ; Burkart, F (CERN) ; Wollmann, D (CERN)
The conceptual design of the Future Circular Collider (FCC) is being carried out actively in an international collaboration hosted by CERN, for the post–Large Hadron Collider (LHC) era. The target center-of-mass energy of proton-proton collisions for the FCC is 100 TeV, nearly an order of magnitude higher than for LHC. [...]

Quarkonia and heavy-flavour results from ALICE / Gagliardi, M (INFN, Turin) /ALICE
Quarkonia and heavy flavour are important probes of the hot and dense QCD medium formed in high-energy heavy-ion collisions, through the modification of their yields and kinematical distributions. Measurements of their production in proton-nucleus collisions are crucial for the interpretation of heavy-ion results, as they allow one to study cold nuclear matter effects [...]

Soft physics and collective phenomena in p-Pb collisions from ALICE / Leogrande, E (Utrecht, Astron. Inst.) /ALICE
New ALICE results concerning soft physics and collective phenomena in p-Pb collisions at $\sqrt{SNN}$ = 5.02 TeV are briefly discussed. First, the particle-multiplicity dependence of the flow coefficients $\upsilon_{2}$ and $\upsilon_{3}$ derived via multiparticle cumulants is reviewed. [...]

First observation and study of $K^\pm \to \pi^\pm \pi^0 e^+ e^-$ decay at the NA48/2 experiment / Misheva, M H (Dubna, JINR) ; Anzivino, G ; Arcidiacono, R ; Balev, S ; Batley, J R ; Behler, M ; Bi­fani, S ; Biino, C ; Bizzeti, A ; Bloch-Devaux, B et al.
A sample of almost 2000 $K^\pm \to \pi^\pm \pi^0 e^+ e^-$ rare decays with a background contamination below 3% is observed for the first time by the NA48/2 experiment at CERN/SPS. The preliminary branching ratio in the full kinematic region is obtained to be $BR(K^\pm \to \pi^\pm \pi^0 e^+ e^-)$ = (4.06 ± 0.17) x $10^{-6}$ by analyzing the data set recorded in 3-month NA48/2 run during 2003.

Searches for Dark Matter and Extra Dimensions at the LHC / Demiragli, Z (MIT) /CMS ; ATLAS
The $CMS^1$ and $ATLAS^2$ collaborations at the Large Hadron Coltider have collected approx­ imately $20fb^{-1}$ of pp collision data with center-of-mass energy of 8 TeV and have performed targeted searches for Dark Matter and Extra Dimensions. No significant deviations from the standard model prediction have been observed. [...]

Searches for other non-SUSY new phenomena at the LHC / Kajomovitz, E (Duke U.) /ATLAS ; CMS
The ATLAS and CMS collaborations collected datasets of approximately $20 fb^{-1}$ of $pp$ collisions at $\sqrt{s}$ = 8 TeV produced by the LHC during the Run-1 period. The collaborations performed a thorough analysis of these datasets searching for physics phenomena beyond the Standard Model. [...]

Strong Production SUSY Searches at ATLAS and CMS / Marshall, Z L (LBL, Berkeley) /ATLAS ; CMS
The results of searches for strongly-produced supersymmetry at the Large Hadron Collider by the ATLAS and CMS collaborations are presented. Several of the historically strongest zero-and one-lepton final state searches have been updated to include multi-bin fits and combinations. [...]

Assuming Regge trajectories in holographic QCD: from OPE to Chiral Perturbation Theory / Cappiello, Luigi (Naples U. ; INFN, Naples) ; D'Ambrosio, Giancarlo (INFN, Naples ; CERN) ; Greynat, David (Naples U. ; INFN, Naples)
The Soft Wall model in holographic QCD has Regge trajectories but wrong operator product expansion (OPE) for the two-point vectorial QCD Green function. We correct analytically this problem and describe the axial sector and chiral symmetry breaking. [...]
