Abstract

The TORCH time-of-flight detector is designed for large-area coverage, up to 30m^2, to provide particle identification between 2-10 GeV/c momentum over a flight distance of 10 m. The arrival times from Cherenkov photons produced within a quartz radiator plate of 10mm thickness are combined to achieve a 15 ps time-of-flight resolution per incident particle. Micro-Channel Plate Photomultiplier Tube (MCP-PMT) detectors of 53 X 53mm^2 active area have been developed with industrial partners for the TORCH application. The MCP-PMT is read out using charge division to give a 128 X 8 effective granularity. Laboratory results of development MCP-PMTs will be described, and testbeam studies using a small-scale TORCH prototype module will be presented.

Abstract

The TORCH detector will provide charged particle pi/K/p identification up to 10 GeV/c, combining Time-of-Flight and Cherenkov techniques to achieve a timing resolution of 70 ps for single photons. Based on a scalable design, a Time-of-Flight electronics readout system has been developed to instrument a novel customized 512-channel Micro Channel Plate (MCP) device. A Gigabit Ethernet-based readout scheme that operates the TORCH demonstration unit consisting of ten such MCPs will be reported. The trigger and clock distribution will also be discussed.

Abstract

A search is performed for the central exclusive production of pairs of charmonia produced in proton-proton collisions. Using data corresponding to an integrated luminosity of $3{\rm\ fb}^{-1}$ collected at centre-of-mass energies of 7 and 8 TeV, $J/\psi J/\psi$ and $J/\psi\psi(2S)$ pairs are observed, which have been produced in the absence of any other activity inside the LHCb acceptance that is sensitive to charged particles in the pseudorapidity ranges $(-3.5,-1.5)$ and $(1.5,5.0)$. Searches are also performed for pairs of P-wave charmonia and limits are set on their production. The cross-sections for these processes, where the dimeson system has a rapidity between 2.0 and 4.5, are measured to be $$ \begin{array}{rl} \sigma^{J/\psi J/\psi} &= 58\pm10{(\rm stat)} \pm 6{(\rm syst)} {\rm\ pb} , \\ \sigma^{J/\psi\psi(2S)} &= 63 ^{+27}_{-18}{(\rm stat)}\pm 10{(\rm syst)} {\rm\ pb} , \\ \sigma^{\psi(2S)\psi(2S)} &< 237 {\rm\ pb}, \\ \sigma^{\chi_{c0}\chi_{c0}} &< 69 {\rm\ nb}, \\ \sigma^{\chi_{c1}\chi_{c1}} &< 45 {\rm\ pb}, \\ \sigma^{\chi_{c2}\chi_{c2}} &< 141 {\rm\ pb}, \\ \end{array} $$ where the upper limits are set at the 90% confidence level. The measured $J/\psi J/\psi$ and $J/\psi\psi(2S)$ cross-sections are consistent with theoretical expectations., Comment: 21 pages, 5 figures

Abstract

Exclusive $J/\psi$ and $\psi(2S)$ vector meson production has been observed in the dimuon channel using the LHCb detector. The cross-section times branching fractions to two muons with pseudorapidities between 2.0 and 4.5 are measured to be $ \sigma_{pp\rightarrow J/\psi (\rightarrow \mu^{+} \mu^{-})} (2.0

Abstract

DIRAC, the LHCb community Grid solution, was considerably reengineered in order to meet all the requirements for processing the data coming from the LHCb experiment. It is covering all the tasks starting with raw data transportation from the experiment area to the grid storage, data processing up to the final user analysis. The reengineered DIRAC3 version of the system includes a fully grid security compliant framework for building service oriented distributed systems; complete Pilot Job framework for creating efficient workload management systems; several subsystems to manage high level operations like data production and distribution management. The user interfaces of the DIRAC3 system providing rich command line and scripting tools are complemented by a full-featured Web portal providing users with a secure access to all the details of the system status and ongoing activities. We will present an overview of the DIRAC3 architecture, new innovative features and the achieved performance. Extending DIRAC3 to manage computing resources beyond the WLCG grid will be discussed. Experience with using DIRAC3 by other user communities than LHCb and in other application domains than High Energy Physics will be shown to demonstrate the general-purpose nature of the system.

Abstract

The Dokshitzer, Gribov, Lipatov, Alterelli, Parisi and Ciafaloni, Catani, Fiorani, Marchesini approaches to perturbative QCD evolution have been investigated by examining correlations of charmed hadron pairs in pp collisions at TeV. The theoretical models are compared to the data taken by the LHCb experiment. Differences in the parton kinematics between the two approaches are discussed. In general a model incorporating next-leading-order diagrams matched to parton showers describes the data best. [ABSTRACT FROM AUTHOR]

Abstract

Measurements of the branching fractions of $B_{s}^{0}\to {{K}^{*\pm }}{{K}^{\mp }}$ and $B_{s}^{0}\to {{K}^{*\pm }}{{\pi }^{\mp }}$ decays are performed using a data sample corresponding to $1.0\ {\rm f}{{{\rm b}}^{-1}}$ of proton-proton collision data collected with the LHCb detector at a centre-of-mass energy of $7\;{\rm TeV}$ , where the ${{K}^{*\pm }}$ mesons are reconstructed in the $K_{S}^{0}{{\pi }^{\pm }}$ final state. The first observation of the $B_{s}^{0}\to {{K}^{*\pm }}{{K}^{\mp }}$ decay and the first evidence for the $B_{s}^{0}\to {{K}^{*-}}{{\pi }^{+}}$ decay are reported with branching fractions \begin{eqnarray*}\begin{array}{rcl} \bf{\mathcal{B}}\left( B_{s}^{0}\to {{K}^{*\pm }}{{K}^{\mp }} \right) & = & \left( 12.7\pm 1.9\pm 1.9 \right)\times {{10}^{-6}}, \\ \bf{\mathcal{B}}\left( B_{s}^{0}\to {{K}^{*-}}{{\pi }^{+}} \right) & = & \left( 3.3\pm 1.1\pm 0.5 \right)\times {{10}^{-6}}, \\ \end{array}\end{eqnarray*} where the first uncertainties are statistical and the second are systematic. In addition, an upper limit of $\mathcal{B}\left( {{B}^{0}}\to {{K}^{*\pm }}{{K}^{\mp }} \right)\lt 0.4\ (0.5)\times {{10}^{-6}}$ is set at $90\%\ (95\%)$ confidence level.
