Osseous tools and personal ornaments from the Epigravettian sequence at Badanj

The Late Upper Palaeolithic (Epigravettian) sequence at Badanj has yielded an important dataset about the occupation of the hinterland of the Eastern Adriatic catchment zone in the late Pleniglacial. The site also harbors one of the rare occurrences of Upper Palaeolithic parietal “art” in southeastern Europe in the form of a large rock engraving. Another notable aspect of the site is the presence of engravings on portable objects made from bone. The first excavations at Badanj, conducted in 1976–1979 in the zone around the engraved rock, yielded a surprisingly large number of personal ornaments (over 1000 specimens) from a variety of primarily marine gastropods, scaphopods, and bivalves, and red deer canines. Here we review what is currently known about the site and report our preliminary findings from the study of the collection of personal ornaments as well as osseous tools, some of which were marked by regular incisions forming decorative motifs. We also report two new direct accelerator mass spectrometry (AMS) dates on antler barbed points

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
