title: "Figure 10c of Auxiliary Material" of "Search for neutral long-lived particles that decay into displaced jets in the ATLAS calorimeter in association with leptons or jets using $pp$ collisions at $\sqrt{s}=13$ TeV"

description: Signal efficiencies as a function of cτ for ZALP, HZZ<sub>d</sub> and ZHS signals in the CalR+Z channel for (a, b) the CalR+Z low-E<sub>T</sub> selection and (c, d) the CalR+Z high-E<sub>T</sub> selection. The extrapolation of efficiencies to new mean LLP lifetimes is done via the event reweighting procedure. Only statistical uncertainties are shown.
description: A search for neutral long-lived particles (LLPs) decaying in the ATLAS hadronic calorimeter using 140~fb$^{-1}$ of proton--proton collisions at $\sqrt{s}=13$ TeV delivered by the LHC is presented. The analysis is composed of three channels. The first targets pair-produced LLPs, where at least one LLP is produced with sufficiently low boost that its decay products can be resolved as separate jets. The second and third channels target LLPs respectively produced in association with a $W$ or $Z$ boson that decays leptonically. In each channel, different search regions target different kinematic regimes, to cover a broad range of LLP mass hypotheses and models. No excesses of events relative to the background predictions are observed. Higgs boson branching fractions to pairs of hadronically decaying neutral LLPs larger than 1% are excluded at 95% confidence level for proper decay lengths in the range of 30~cm to 4.5~m depending on the LLP mass, a factor of three improvement on previous searches in the hadronic calorimeter. The production of long-lived dark photons in association with a $Z$ boson with cross-sections above 0.1~pb is excluded for dark photon mean proper decay lengths in the range of 20~cm to 50~m, improving previous ATLAS results by an order of magnitude. Finally, long-lived photo-phobic axion-like particle models are probed for the first time by ATLAS, with production cross-sections above 0.1~pb excluded in the 0.1~mm to 10~m range.

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. However, the contents and opinions contained herein do not necessarily reflect the views or policies of the Department of the Interior, nor does the mention of trade names or commercial products constitute endorsement or recommendation by the Department of the Interior.
