title: "Figure 14.4" of "The azimuthal correlation between the leading jet and the scattered lepton in deep inelastic scattering at HERA"

description: The correlation matrix for $10 \;\mathrm{GeV}^{2} &lt; Q^{2} &lt; 50 \;\mathrm{GeV}^{2}$. Other details are as in the caption to Fig. 13.
description: The azimuthal correlation angle, $\Delta\phi$, between the scattered lepton and the leading jet in deep inelastic $e^{\pm}p$ scattering at HERA has been studied using data collected with the ZEUS detector at a centre-of-mass energy of $\sqrt{s} = 318 \;\mathrm{GeV}$, corresponding to an integrated luminosity of $326 \;\mathrm{pb}^{-1}$.A measurement of jet cross sections in the laboratory frame was made in a fiducial region corresponding to photon virtuality $10 \;\mathrm{GeV}^{2} &lt; Q^{2} &lt; 350 \;\mathrm{GeV}^{2}$, inelasticity $0.04 &lt; y &lt; 0.7$, outgoing lepton energy $E_e &gt; 10 \;\mathrm{GeV}$, lepton polar angle $140^\circ &lt; \theta_e &lt; 180^\circ$, jet transverse momentum $2.5 \;\mathrm{GeV} &lt; p_\mathrm{T,jet} &lt; 30 \;\mathrm{GeV}$, and jet pseudorapidity $-1.5 &lt; \eta_\mathrm{jet} &lt; 1.8$.Jets were reconstructed using the $k_\mathrm{T}$ algorithm with the radius parameter $R = 1$.The leading jet in an event is defined as the jet that carries the highest $p_\mathrm{T,jet}$.Differential cross sections, $d\sigma/d\Delta\phi$, were measured as a function of the azimuthal correlation angle in various ranges of leading-jet transverse momentum, photon virtuality and jet multiplicity.Perturbative calculations at $\mathcal{O}(\alpha_{s}^2)$ accuracy successfully describe the data within the fiducial region, although a lower level of agreement is observed near $\Delta\phi \rightarrow \pi$ for events with high jet multiplicity, due to limitations of the perturbative approach in describing soft phenomena in QCD.The data are equally well described by Monte Carlo predictions that supplement leading-order matrix elements with parton showering.

title: Hancock Photographs

description: The Hancock Foundation Archive consists of correspondence, reports, clippings, photographs, sound recordings, film, and other materials, 1823-2005, documenting the activities and history of the Hancock Foundation at the University of Southern California, its founder G. Allan Hancock, and the Hancock family. Included are records of the Foundation's scientific and research activities in marine biology and zoology; the Foundation's Library; the Hancock Museum, housed in the Foundation building on the USC campus; and the research vessel Velero IV, the second of Captain Hancock's ships put into service for research purposes. Also included are historical documents regarding the Hancock family's land interests in Los Angeles, and material documenting the non-scientific interests of Captain Hancock. Specifically this digital collection includes: • Allan Hancock Foundation publications. • Sound recordings produced by the Allan Hancock Foundation for radio broadcast in the 1930's and 1940's. Many of the recordings are of the Hancock Ensemble whose 'cellist was Allan Hancock. Digitized thanks to generous support from the Association for Recorded Sound Collections (ARSC) (https://www.arsc-audio.org/index.php), Lance Bowling and Cambria Music, Kenneth Hayashida MD (USC ’89) • Films and photographs from the Allan Hancock Foundation mostly from the expeditions of the research vessels Velero II, III, and IV. The digitization efforts for the Hancock collection have been financed (in part) with Federal funds from the National Park Service Maritime Heritage grant program (https://www.nps.gov/maritime/grants/apply.htm), administered by the National Park Service, U.S. Department of the Interior.

description: Simulated distributions of the number of μLJ candidates for a selection of γ<sub>d</sub> mass values.

description: A search for a dark photon, a new light neutral particle, which decays promptly into collimated pairs of electrons or muons is presented. The search targets dark photons resulting from the exotic decay of the Standard Model Higgs boson, assuming its production via the dominant gluon-gluon fusion mode. The analysis is based on 140 fb <sup>-1</sup> of data collected with the ATLAS detector at the Large Hadron Collider from proton-proton collisions at a center-of-mass energy of 13 TeV. Events with collimated pairs of electrons or muons are analysed and background contributions are estimated using data-driven techniques. No significant excess in the data above the Standard Model background is observed. Upper limits are set at 95&percnt; confidence level on the branching ratio of the Higgs boson decay into dark photons between 0.001&percnt; and 5&percnt;, depending on the assumed dark photon mass and signal model.
