$\sin(2\beta)$ with $B^0 \rightarrow\!J/\!\psi K_\text{S}$ at the LHCb experiment
 Reference: Poster-2015-482 Keywords:  LHCb Created: 2015. -1 p Creator(s): Niet, Ramon The poster presents the recent measurement of $\sin(2\beta)$ using $B^0$ decays to the $J/\!\psi K_\text{S}$ final state. The measurement is based on a dataset corresponding to an integrated luminosity of 3.0$\,\text{fb}^{-1}$ collected with the LHCb experiment in proton-proton collisions at center-of-mass energies of 7 and 8 TeV. To control penguin pollutions in the determination of $\sin(2\beta)$, $B_s^0$ decays to the same final state can be analysed. The results of the corresponding analysis are presented as well.

Indico
 Reference: Poster-2015-466 Created: 2012. -1 p Creator(s): Ferreira, Pedro Indico was born as a European project. In 2004, CERN became the sole owner of the project and decided to further extend its capabilities, enabling CERN users to manage lectures and meetings as well. This allowed Indico to replace the 'CERN Agenda' application. In 2007, a Room Booking module was added, thus allowing CERN users to book their rooms on-line. Indico became, in 2009, CERN's hub for collaborative tools, empowering collaborations such as the LHC and its experiments with video conferencing and chatting capabilities. Since then, several other features have been developed, such as a full-fledged paper reviewing module for conferences and a powerful HTTP API. © CERN Geneva Access to files

The keys to CERN conference rooms - Managing local collaboration facilities in large organisations
 Reference: Poster-2015-465 Created: 2013. -1 p Creator(s): Baron, T; Domaracky, M; Duran, G; Correia Fernandes, J; Ferreira, P [...] For a long time HEP has been ahead of the curve in its usage of remote collaboration tools, like videoconference and webcast, while the local CERN collaboration facilities were somewhat behind the expected quality standards for various reasons. This time is now over with the creation by the CERN IT department in 2012 of an integrated conference room service which provides guidance and installation services for new rooms (either equipped for video-conference or not), as well as maintenance and local support. Managing now nearly half of the 250 meeting rooms available on the CERN sites, this service has been built to cope with the management of all CERN rooms with limited human resources. This has been made possible by the intensive use of professional software to manage and monitor all the room equipment, maintenance and activity. This paper will focus on presenting these packages, either off-the-shelf commercial products (asset and maintenance management tool, remote audiovisual equipment monitoring systems, local automation devices, new generation touch screen interfaces for interacting with the room) when available or locally developed integration and operational layers (generic audiovisual control and monitoring framework) and how they help overcoming the challenges presented by such a service. The aim is to minimise local human interventions while preserving the highest service quality and placing the end user back to the center of this collaboration platform. © CERN Geneva Access to files

CORAL and COOL during the LHC long shutdown
 Reference: Poster-2013-399 Created: 2013. -1 p Creator(s): Valassi, A; Clemencic, M; Dykstra, D; Goyal, N; Salnikov, A [...] CORAL and COOL are two software packages used by the LHC experiments for managing detector conditions and other types of data using relational database technologies. They have been developed and maintained within the LCG Persistency Framework, a common project of the CERN IT department with ATLAS, CMS and LHCb. This presentation reports on the status of CORAL and COOL at the time of CHEP2013, covering the new features and enhancements in both packages, as well as the changes and improvements in the software process infrastructure. It also reviews the usage of the software in the experiments and the outlook for ongoing and future activities during the LHC long shutdown (LS1) and beyond.

Handling Worldwide LHC Computing Grid Critical Service Incidents : The infrastructure and experience behind nearly 5 years of GGUS ALARMs
 Reference: Poster-2013-391 Keywords:  WLCG  GGUS  ALARM  ticket  Storage  CASTOR  Batch  LSF  CERN  KIT  fail-safe  Tier0  Tier1  workflow  incident Created: 2013. -1 p Creator(s): Dimou, M; Dres, H; Dulov, O; Grein, G In the Wordwide LHC Computing Grid (WLCG) project the Tier centres are of paramount importance for storing and accessing experiment data and for running the batch jobs necessary for experiment production activities. Although Tier2 sites provide a significant fraction of the resources a non-availability of resources at the Tier0 or the Tier1s can seriously harm not only WLCG Operations but also the experiments' workflow and the storage of LHC data which are very expensive to reproduce. This is why availability requirements for these sites are high and committed in the WLCG Memorandum of Understanding (MoU). In this talk we describe the workflow of GGUS ALARMs, the only 24/7 mechanism available to LHC experiment experts for reporting to the Tier0 or the Tier1s problems with their Critical Services. Conclusions and experience gained from the detailed drills performed in each such ALARM for the last 4 years are explained and the shift with time of Type of Problems met. The physical infrastructure put in place to achieve GGUS 24/7 availability are summarised.
