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

A Wedding Gone Wrong The Rather Worldly Woes of a Rather Wealthy Qādirī Sufi Shaykh. Two 18th Century Documents from the Ottoman Court Records of Ḥamā and Aleppo

A rather intricate legal case took place first in Ḥamā’s and then in Aleppo’s Ottoman Islamic courts around the middle of the 18th century. The setting, the social standing of the individuals involved, and the alleged circumstances of the case all contribute to make clear that this was not just another routine court case. Altogether, the two documents are a good example of the scope and quality of the information preserved in the archives of local courts and they both demonstrate the extent and modes of implementation of Islamic law in a specific Ottoman milieu. The long inventory of personal property in the Aleppo document gives us a good idea of the social status and affluence enjoyed by the plaintiff – a member of the Jīlānī/Qādirī family - and an interesting insight into material culture and what constituted wealth and affluence at the time.
