title: "Table 44" of "Combination of searches for Higgs boson pair production in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector"

description: Expected value of the test statistic (-2ln$\Lambda$), as a function of the $c_{tthh}$ parameter for $b\bar{b}\tau\tau$.
description: This Letter presents results from a combination of searches for Higgs boson pair production using 126--140 fb$^{-1}$ of proton--proton collision data at $\sqrt{s}=13$ TeV recorded with the ATLAS detector. At 95% confidence level (CL), the upper limit on the production rate is 2.9 times the Standard Model (SM) prediction, with an expected limit of 2.4 assuming no Higgs boson pair production. Constraints on the Higgs boson self-coupling modifier $\kappa_{\lambda}=\lambda_{HHH}/\lambda_{HHH}^\mathrm{SM}$, and the quartic $HHVV$ coupling modifier $\kappa_{2V}=g_{HHVV}/g_{HHVV}^\mathrm{SM}$, are derived individually, fixing the other parameter to its SM value. The observed 95% CL intervals are $-1.2 &lt; \kappa_{\lambda} &lt; 7.2$ and $0.6 &lt; \kappa_{2V} &lt; 1.5$ respectively, while the expected intervals are $-1.6 &lt; \kappa_{\lambda} &lt; 7.2$ and $0.4 &lt; \kappa_{2V} &lt; 1.6$ in the SM case. Constraints obtained for several interaction parameters within Higgs effective field theory are the strongest to date, offering insights into potential deviations from SM predictions.

title: "Figure 2a" of "Combination of searches for singly produced vector-like top quarks in pp collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector"

description: Observed and expected 95% CL upper limits on the total cross-section σ($pp$ → $T$ → $Ht/Zt$) as a function of $T$-quark mass in the SU(2) singlet representation assuming $\kappa$=0.3. The expected limits for the individual analyses are shown. The $HtZt$ analysis is only included in the limit calculation for $m_{\mathrm{T}}$ &lt; 2.1 TeV.
description: A combination of searches for the single production of vector-like top quarks ($T$) is presented. These analyses are based on proton--proton collisions at $\sqrt{s}=13$ $TeV$ recorded in 2015--2018 with the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of 139 fb$^{-1}$. The $T$-quark decay modes considered in this combination are into a top quark and either a Standard Model Higgs boson or a $Z$ boson ($T \to Ht$ and $T \to Zt$). The individual searches used in the combination are differentiated by the number of leptons ($e$, $\mu$) in the final state. The observed data are found to be in good agreement with the Standard Model background prediction. Interpretations are provided for a range of masses and couplings of the vector-like top quark for benchmark models and generalized representations in terms of 95 % confidence level limits. For a benchmark signal prediction of a vector-like top quark $SU(2)$ singlet with electroweak coupling, $\kappa$, of 0.5, masses below 2.1 TeV are excluded, resulting in the most restrictive limits to date.

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.
