Development of an MCP-Based Timing Layer for the LHCb ECAL Upgrade-2 / Perazzini, Stefano (INFN, Bologna) ; Ferrari, Fabio (INFN, Bologna ; U. Bologna, DIFA) ; Vagnoni, Vincenzo Maria (INFN, Bologna) /LHCb ECAL Upgrade-2 R&D Group
The increase in instantaneous luminosity during the high-luminosity phase of the LHC represents a significant challenge for future detectors. A strategy to cope with high-pileup conditions is to add a fourth dimension to the measurements of the hits, by exploiting the time separation of the various proton–proton primary collisions. [...]

The 40 MHz trigger-less DAQ for the LHCb Upgrade / Campora Perez, D H (INFN, CNAF) ; Falabella, A (CERN) ; Galli, D (OCEM, Bologna ; Bologna U.) ; Giacomini, F (CERN) ; Gligorov, V (INFN, CNAF) ; Manzali, M (Bologna U. ; Ferrara U.) ; Marconi, U (OCEM, Bologna) ; Neufeld, N (INFN, CNAF) ; Otto, A (INFN, CNAF) ; Pisani, F (INFN, CNAF ; Rome U.) et al.
The LHCb experiment will undergo a major upgrade during the second long shutdown (2018–2019), aiming to let LHCb collect an order of magnitude more data with respect to Run 1 and Run 2. The maximum readout rate of 1 MHz is the main limitation of the present LHCb trigger. [...]

The FIT-pull Method : an experimental tool to monitor the track measurements and the B proper time. / Balbi, G ; Vagnoni, V M ; Vecchi, S
In this note we describe a statistical tool, the \textit{FIT-pull method}, that can test the reliability of the measurements of the tracks and the vertices on real and Monte-Carlo data without knowledge of the truth information. The basic mathematical formalism is derived from the Lagrange Multipliers method and briefly described. [...]

Reliability of datagram transmission on Gigabit Ethernet at full link load / Barczyk, A ; Carbone, A ; Dufey, J P ; Galli, D ; Jost, B ; Marconi, U ; Neufeld, N ; Peco, G ; Vagnoni, V M
The reliability of datagram transmission over Copper Gigabit Ethernet using commodity hardware at sustained Gb/s rate is crucial for the functioning of the software trigger layers of the LHCb experiment. We aim to demonstrate that a nowadays available high-end commodity PC can be employed to achieve the required network performance, in particular to implement a sub-farm controller node. [...]

Study of the $K^{+}K^{-} \pi^{+}\pi^{-}\pi^{0}$ final state in antiproton annihilation at rest in gaseous hydrogen at NTP with the OBELIX spectrometer / OBELIX Collaboration
A spin-parity analysis of a sample of pp to K/sup +/K/sup -/ pi /sup +/ pi /sup -/ pi /sup 0/ annihilation events taken at rest in gaseous H/sub 2/ at NTP is reported. The invariant mass spectrum of the K/sup +/K/sup -/ pi /sup 0/ system shows the presence of the E/t resonance pattern at 1.42 GeV. [...]

Selection of B0(s)-->h+h- decays at LHCb / Balbi, G (Bologna U. ; INFN, Bologna) ; Bargiotti, M (Bologna U. ; INFN, Bologna) ; Bertin, A (Bologna U. ; INFN, Bologna) ; Bruschi, M (Bologna U. ; INFN, Bologna) ; Carbone, A (Bologna U. ; INFN, Bologna) ; Fabbri, Franco Luigi (Bologna U. ; INFN, Bologna) ; Faccioli, P (Bologna U. ; INFN, Bolognau) ; Galli, D (Bologna U. ; INFN, Bologna) ; Giacobbe, B (Bologna U. ; INFN, Bologna) ; Gregori, D (Bologna U. ; INFN, Bologna) et al.
The selection of B0-->pi+pi-, B0-->K+pi-, Bs-->K+K- and Bs-->pi+K- decays, which are traditionally chosen as benchmark channels to demonstrate the physics potential of the detector for fully hadronic modes, is presented. The strategy followed to identify the best selection cuts is described. [...]

CP sensitivity with B0(s)-> h+h- decays at LHCb / Balbi, G (Bologna U. ; INFN, Bologna) ; Bargiotti, M (Bologna U. ; INFN, Bologna) ; Bertin, A (Bologna U. ; INFN, Bologna) ; Bruschi, M (Bologna U. ; INFN, Bologna) ; Carbone, A (Bologna U. ; INFN, Bologna) ; Fabbri, Franco Luigi (Bologna U. ; INFN, Bologna) ; Faccioli, P (Bologna U. ; INFN, Bologna) ; Galli, D (Bologna U. ; INFN, Bologna) ; Giacobbe, B (Bologna U. ; INFN, Bologna) ; Gregori, D (Bologna U. ; INFN, Bologna) et al.
LHCb can collect large samples of B0-->pi+pi-, B0-->K+pi-, Bs-->K+K- and Bs-->pi+K- decays. The sensitivity achievable on the corresponding Bs-->pi+direct and mixing-induced CP-violating observables has been studied in detail. [...]

First implementation of a diskless computing farm for the LHCb italian Tier-1 prototype / Avoni, G (INFN, Bologna) ; Bargiotti, M (Bologna U. ; INFN, Bologna) ; Bertin, A (Bologna U. ; INFN, Bologna) ; Bruschi, M (INFN, Bologna) ; Capponi, M (Bologna U. ; INFN, Bologna) ; De Castro, S (Bologna U. ; INFN, Bologna) ; Fabbri, Franco Luigi (Bologna U. ; INFN, Bologna) ; Faccioli, P (Bologna U. ; INFN, Bologna) ; Galli, D (Bologna U. ; INFN, Bologna) ; Giacobbe, B (Bologna U. ; INFN, Bologna) et al.
Aim of this paper is to outline the designing criteria which guided us in the design and the realization of a computing farm for the LHCb Italian Tier-1 prototype. The hardware architecture, with particular attention paid to the disk data storage and to the disk-less implementation of the farm nodes, is described. [...]
