This thesis work is part of the precision tests done at LEP2. The W boson pairs are produced
through e+ e-collisions. The fully leptonic final states (lvlv) correspond to 10.5% of the …

The Level-1 trigger is the first event rate reducing step in the ATLAS detector trigger system,
with an output rate of up to 100 kHz and decision latency smaller than 2.5 μs. During the …

The ATLAS trigger has been used very successfully to collect collision data during 2009 and
2010 LHC running at center-of-mass energies of 900 GeV, 2.36 TeV and 7 TeV. It is …

The ATLAS experiment is designed to study the proton-proton collisions produced at the
Large Hadron Collider at CERN. During the early Run 2 data-taking period, the ATLAS …

The ATLAS experiment is designed to study the proton-proton collisions produced at the
Large Hadron Collider at CERN. During the Run 1 data taking, the ATLAS trigger and data …

During 2006 and spring 2007, integration and commissioning of trigger and data acquisition
(TDAQ) equipment in the ATLAS experimental area has progressed. Much of the work has …

Recent measurements of top-quark pair production in association with W-bosons, Z-bosons,
photons and b-tagged jets are reported. The measurements are based on ATLAS and CMS …

The ATLAS and CMS experiments at CERN are planning a second phase of upgrades to
prepare for the" High Luminosity LHC", with collisions due to start in 2026. In order to deliver …

Analytic compartmental models are currently used in mathematical epidemiology to forecast
the COVID-19 pandemic evolution and explore the impact of mitigation strategies. In …

A study of the systematic uncertainty coming from the background estimation in the W mass
measurement has been done. The high statistics data taken in 1994 compared with the …
