R&D on high momentum particle identification with a pressurized Cherenkov radiator / Agócs, A G (Wigner RCP, Budapest) ; Barile, F (Bari U. ; INFN, Bari) ; Barnaföldi, G G (Wigner RCP, Budapest) ; Bellwied, R (Houston U.) ; Bencédi, G (Wigner RCP, Budapest) ; Bencze, G (Wigner RCP, Budapest) ; Berényi, D (Wigner RCP, Budapest) ; Boldizsár, L (Wigner RCP, Budapest) ; Chattopadhyay, S (Saha Inst.) ; Chinellato, D D (Houston U.) et al.
We report on the R&D; results for a Very High Momentum Particle Identification (VHMPID) detector, which was proposed to extend the charged hadron track-by-track identification in the momentum range from 5 to 25 GeV/ c in the ALICE experiment at CERN. It is a RICH detector with focusing geometry using pressurized perfluorobutane (C 4 F 8 O) as a Cherenkov radiator. [...]

A small-size prototype of a new Ring Imaging Cherenkov (RICH) detector using for the first time pressurized C4F8O radiator gas and a photon detector consisting of MWPC equipped with a CsI photocathode has been built and tested at the PS accelerator at CERN. It contained all the functional elements of the detector proposed as Very High Momentum Particle Identification (VHMPID) upgrade for the ALICE experiment at LHC to provide charged hadron track-by-track identification in the momentum range starting from 5 potentially up to 25 GeV/c.

R&D studies of a RICH detector using pressurized C$_{4}$F$_{8}$O radiator gas and a CsI-based gaseous photon detector / Agócs, A.G (Budapest, RMKI) ; Barile, F (Bari U ; INFN, Bari) ; Barnaföldi, G.G (Budapest, RMKI) ; Bellwied, R (Houston U.) ; Bencédi, G (Budapest, RMKI) ; Bencze, G (Budapest, RMKI) ; Berényi, D (Budapest, RMKI) ; Boldizsár, L (Budapest, RMKI) ; Chattopadhyay, S (Matrivani Inst., Calcutta) ; Chinellato, D.D (Houston U.) et al.
We report on studies of layout and performance of a new Ring Imaging Cherenkov detector using for the fi rst time pressurized C 4 F 8 O radiator gas and a photon detector consisting of a MWPC equipped with a CsI photocathode. In particular, we present here the results of beam tests of a MWPC having an adjustable anode – cathode gap, aiming at the optimization of single photoelectron detection and Cherenkov angle resolution.

A Very High Momentum Particle Identification Detector / ALICE Collaboration
The construction of a new detector is proposed to extend the capabilities of ALICE in the high transverse momentum (pT) region. This Very High Momentum Particle Identification Detector (VHMPID) performs charged hadron identification on a track-by-track basis in the 5 GeV/c < p < 25 GeV/c momentum range and provides ALICE with new opportunities to study parton-medium interactions at LHC energies.

Upgrade of the ALICE Experiment: Letter of Intent / ALICE Collaboration
The long term goal of the ALICE experiment is to provide a precise characterization of the high-density, high-temperature phase of strongly interacting matter. To achieve this goal, high-statistics precision measurement are required. [...]

Suppression of high transverse momentum D mesons in central Pb--Pb collisions at $\sqrt{s_{NN}}=2.76$ TeV / ALICE Collaboration
The production of the prompt charm mesons $D^0$, $D^+$, $D^{*+}$, and their antiparticles, was measured with the ALICE detector in Pb-Pb collisions at the LHC, at a centre-of-mass energy $\sqrt{s_{NN}}=2.76$ TeV per nucleon--nucleon collision. The $p_t$-differential production yields in the range $2<p_t<16$ GeV/c at central rapidity, $|y|<0.5$, were used to calculate the nuclear modification factor $R_{AA}$ with respect to a proton-proton reference obtained from the cross section measured at $\sqrt{s}=7$ TeV and scaled to $\sqrt{s}=2.76$ TeV. [...]

Inclusive J/$\psi$ production in pp collisions at $\sqrt{s}$ = 2.76 TeV / ALICE Collaboration
The ALICE Collaboration has measured inclusive J/psi production in pp collisions at a center of mass energy sqrt(s)=2.76 TeV at the LHC. The results presented in this Letter refer to the rapidity ranges |y|<0.9 and 2.5<y<4 and have been obtained by measuring the electron and muon pair decay channels, respectively. [...]
