Decays at the LHCb Experiment
A search for the rare decays Bs ! þ and B ! þ is performed at the LHCb experiment. The data analyzed correspond to an integrated luminosity of 1 fb 1 of pp collisions at a center-of-mass energy of 7 TeVand 2 fb 1 at 8 TeV. An excess of Bs ! þ signal candidates with respect to the background expectation is seen with a significance of 4.0 standard deviations. A time-integrated branching fraction ...
متن کاملStatus of the LHCb Experiment
We present the status of the LHCb experiment which will make precision measurements of CP violation in B meson decays. The motivation for the experiment and an overview of the detector design are given. The vertex detector, ring imaging Cherenkov counter, calorimeters, and trigger systems are discussed in detail. We also present the expected physics performance for selected modes. Presented at ...
متن کاملFirst Measurements with the LHCb Experiment
The LHCb detector covers the forward angular region complementary to the angular coverage by the general purpose LHC experiments. With the first data, measurements of inclusive charged particle production and V 0 production will be performed and compared to particle production models. Focusing on ratios, such as positives/negatives or lambda-bar/lambda, many systematic effects cancel and publis...
متن کاملObject Databases in the LHCb Experiment
Database systems are very important in any HEP1 experiment in the world. HEP community in LHC2 era is in transition from FORTRAN to C++ and from data streams to persistent objects. Together with that a new data management will be necessary, which would allow transition from “files and tapes” approach towards the data access in a form of collections of objects containing the required physics inf...
متن کاملSimulation Application for the LHCb Experiment
interfaces for configuration and event-by-event communication. The Gauss application is composed of three main blocks, i.e. event generation, detector response simulation and digitization which reflect the different stages performed during the simulation job. We describe the overall design as well as the details of Gauss application with a special emphasis on the configuration and control of th...
