ALICE upgrades for Run 4 and Run 5
نویسندگان
چکیده
In view of Run 4 at the LHC, presently scheduled from 2029 onwards, ALICE is pursuing several upgrades to further extend its physics reach. order improve heavy-flavor hadron and dielectron measurements which rely on secondary vertexing, a reduction material budget innermost layers Inner Tracking System needed. This can be achieved with bent pixel sensors, arranged in half-cylinder shapes integrated power lines data buses, allowing get rid most supporting structure water cooling. Moreover, new Forward Calorimeter (FoCal), covering pseudorapidities 3.2<η<5.8, has been proposed measure small-x (down 10−6) gluon distributions via prompt photon production. The FoCal will composed highly granular Si+W electromagnetic calorimeter combined conventional sampling hadronic calorimeter, significantly enhance scope for inclusive correlation mesons, photons, jets. For 5 beyond, 3 project proposed. It consists novel compact detector based monolithic silicon ultra-thin near vertex, high readout rate capabilities, superb pointing resolution, excellent tracking particle identification over large acceptance. Such enables rich program, ranging probes ultra-low transverse momenta precision charm beauty sector. identification, sequence systems foreseen: combination Time-Of-Flight system, Ring-Imaging Cherenkov detector, an muon identifier, dedicated forward ultra-soft photons. these proceedings, upgrade plans shown together status R&D ITS3 concepts requirements 3.

Performance of the ATLAS Muon Trigger in Run I and Upgrades for Run II
The ATLAS experiment at the Large Hadron Collider (LHC) has taken data at a centre-of-mass energy between 900 GeV and 8 TeV during Run I (2009-2013). The LHC delivered an integrated luminosity of about 20 fb−1 in 2012, which required dedicated strategies to ensure the highest possible physics output while effectively reducing the event rate. The Muon High Level Trigger has successfully adapted ...
متن کاملLong-Run and Short-Run Causality between Stock Price and Gold Price: Evidence of VECM Analysis from India
The prime objective of the study is to identify the long-run and short-run relationship between Indian stock price viz., BSE SENSEX (hereafter named as BSE) and gold price (GOLD) in India. The daily closing price data were collected for the period of ten years ranging from 1st April 2004 to 31st March 2014 with 2490 observations. The study employed two models: Model one us...
متن کاملImproving Accuracy and Run-Time Performance for TREC-4
For TREC-4, we enhanced our existing prototype that implements relevance ranking using the AT&T DBC-1012 Model 4 parallel database machine to support the entire document collection. Additionally, we developed a special purpose IR prototype to test a new index compression algorithm and to provide performance comparisons to the relational approach. We submitted o cial results for both automatic a...
متن کاملThe Short and Long Run Causality between Agglomeration and Productivity
This study is to investigate the short- and long-run causal relationship between agglomeration (localization and urbanization) economies and labor productivity in the manufacturing sector of 28 Iranian provinces over an 11-year period, 2001–2011. Fully Modified Ordinary Least Squares (FMOLS) method was used to estimate our long-run panel data model. The empirical findings suggested that localiz...
