 2017-08-0111:01 [PUBDB-2017-08780] Journal Article et al Electron efficiency measurements with the ATLAS detector using 2012 LHC proton–proton collision data   This paper describes the algorithms for the reconstruction and identification of electrons in the central region of the ATLAS detector at the Large Hadron Collider (LHC). These algorithms were used for all ATLAS results with electrons in the final state that are based on the 2012 $pp$ collision data produced by the LHC at $\sqrt{s}$ = 8 $TeV$ .

Prototype silicon strip detector modules are currently developed and their performance is studied in both particle test beams and X-ray beams [...] OpenAccess: PDF PDF (PDFA); 2017-07-0313:27 [PUBDB-2017-06655] Report/Journal Article : ; et al The photon PDF from high-mass Drell–Yan data at the LHC [arXiv:1701.08553; DESY-17-015]   Achieving the highest precision for theoretical predictions at the LHC requires the calculation of hard-scattering cross sections that include perturbative QCD corrections up to (N)NNLO and electroweak (EW) corrections up to NLO. Parton distribution functions (PDFs) need to be provided with matching accuracy, which in the case of QED effects involves introducing the photon parton distribution of the proton, $x\gamma (x,Q^2)$ .

To achieve these goals the backgrounds for linear colliders have to be understood in great detail, and both, the machine and the detectors, have to be optimized towards that goal.

These searches make use of proton–proton collision data, collected during 2015 and 2016 at a centre-of-mass energy $\sqrt{s}=13$   $\text {TeV}$ by the ATLAS detector at the large hadron collider, which correspond to an integrated luminosity of $14.7~\mathrm {fb}^{-1}$ .

The measurements are sensitive to the production of a $W$ boson via a triple-gauge-boson vertex and include both the fiducial and differential cross sections of the electroweak process..

The dataset corresponds to an integrated luminosity of 20.2 fb$^{-1}$, recorded with the ATLAS detector at the LHC. [...] OpenAccess: PDF;
