LHCb Level-0 Trigger Detectors

نویسنده

چکیده

The calorimeter and muon systems are essential components to provide a trigger for the LHCb experiment. The calorimeter system comprises a scintillating pad detector and pre-shower, followed by electromagnetic and hadronic calorimeters. The calorimeter system allows photons, electrons and hadrons to be identified, and their energy to bemeasured. Themuon system consists of five measuring stations equipped with Multi-Wire Proportional Chambers (MWPCs) and triple-Gas Electron Multiplier (GEM) detectors, separated by iron filters. It allows the muons identification and transverse momentum measurement. The status of the two systems and their expected performance is presented.

The high level trigger for rare decays at LHCb

The LHCb experiment is dedicated to the study of CP violation and rare B decays. A trigger system is developed to filter these decays from the LHC background environment. An overview of the LHCb trigger strategy is given in this paper as well as an illustration on how the trigger selects the rare decays B d → K * 0 + − and B s → and their control samples, which are used to parametrize possible ...

LHCb detector performance

The LHCb detector is a forward spectrometer at the Large Hadron Collider (LHC) at CERN. The experiment is designed for precision measurements of CP violation and rare decays of beauty and charm hadrons. In this paper the performance of the various LHCb sub-detectors and the trigger system are described, using data taken from 2010 to 2012. It is shown that the design criteria of the experiment h...

Strong Constraints on the Rare Decays

Flavor changing neutral current (FCNC) processes are highly suppressed in the standard model (SM) and thus constitute a stringent test of the current description of particle physics. Precise predictions of the branching fractions of the FCNC decays Bs ! þ and B ! þ , BðBs ! þ Þ 1⁄4 ð3:2 0:2Þ 10 9 and BðB0 ! þ Þ 1⁄4 ð0:10 0:01Þ 10 9 [1,2] make these modes powerful probes in the search for deviat...

Measurement of Bc Mass and Lifetime at LHCb

The potential of measuring the B + c mass and lifetime in LHCb using B + c → J/ψπ + channel is studied. With an integrated luminosity of 1 fb −1 collected at √ s = 14 TeV in LHCb nominal condition, 310 events are expected with B/S less than 2. The statistical errors for mass and lifetime measurement are around 2 MeV/c 2 and 30 fs respectively. LHCb is a forward detector dedicated to precise b p...
