Measurements of $W\gamma$ and $Z\gamma$ production in $pp$ collisions at $\sqrt{s}$ =7  TeV with the ATLAS detector at the LHC


ATLAS Collaboration; Abbott, B; Aad, G; Abajyan, T; Canelli, F; et al (2015). Measurements of $W\gamma$ and $Z\gamma$ production in $pp$ collisions at $\sqrt{s}$ =7 TeV with the ATLAS detector at the LHC. Physical Review D (Particles, Fields, Gravitation and Cosmology), 87:112003.

Abstract

The integrated and differential fiducial cross sections for the production of a $W$ or $Z$ boson in association with a high-energy photon are measured using $pp$ collisions at $\sqrt{s}$ = 7 TeV. The analyses use a data sample with an integrated luminosity of $4.6 fb^{-1}$ collected by the ATLAS detector during the 2011 LHC data-taking period. Events are selected using leptonic decays of the $W$ and $Z$ bosons $[W(e \nu,\mu \nu]$ and $Z(e^+ e^-, \mu^+ \mu^-, \nu \bar{\nu}))$ with the requirement of an associated isolated photon. The data are used to test the electroweak sector of the Standard Model and search for evidence for new phenomena. The measurements are used to probe the anomalous $WW\gamma$, $ZZ\gamma$ and $Z\gamma\gamma$ triple-gauge-boson couplings and to search for the production of vector resonances decaying to $Z\gamma$ and $W\gamma$. No deviations from Standard Model predictions are observed and limits are placed on anomalous triple-gauge-boson couplings and on the production of new vector meson resonances.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
