Measurements of normalized differential cross-sections of top-quark pair production are presented as a function of the top-quark, tt¯ system and event-level kinematic observables in proton–proton collisions at a centre-of-mass energy of s=8TeV. The observables have been chosen to emphasize the tt¯ production process and to be sensitive to effects of initial- and final-state radiation, to the diffe
The results of a search for gluinos in final states with an isolated electron or muon, multiple jets and large missing transverse momentum using proton–proton collision data at a centre-of-mass energy of s=13TeV are presented. The dataset used was recorded in 2015 by the ATLAS experiment at the Large Hadron Collider and corresponds to an integrated luminosity of 3.2 fb- 1. Six signal selections ar
The result of a search for pair production of the supersymmetric partner of the Standard Model bottom quark (b~1) is reported. The search uses 3.2 fb- 1 of pp collisions at s=13 TeV collected by the ATLAS experiment at the Large Hadron Collider in 2015. Bottom squarks are searched for in events containing large missing transverse momentum and exactly two jets identified as originating from b-quark
This Letter presents a measurement of the inelastic proton-proton cross section using 60 μb-1 of pp collisions at a center-of-mass energy s of 13 TeV with the ATLAS detector at the LHC. Inelastic interactions are selected using rings of plastic scintillators in the forward region (2.0710-6, where MX is the larger invariant mass of the two hadronic systems separated by the largest rapidity gap in t
We report the measurements of correlations between event-by-event fluctuations of amplitudes of anisotropic flow harmonics in nucleus-nucleus collisions, obtained for the first time using a new analysis method based on multiparticle cumulants in mixed harmonics. This novel method is robust against systematic biases originating from nonflow effects and by construction any dependence on symmetry pla

The specific way the Athenians set up their democracy presents both theoretical and empirical challenges. Decisions were taken by majority vote in the Assembly. To keep politicians in line, the Athenians first used ostracism, which however was replaced by the graphe paranomon around 415 BCE. The latter provided that anybody who had made a proposal in the Assembly could be accused of having made an
Education and wealth are positively correlated for individuals approaching retirement, but the direction of the causal relationship is ambiguous in theory and has not been identified in practice. We combine administrative data on individual total wealth with a reform expanding access to lower secondary school in Denmark in the 1950s, finding that schooling increases pension annuity claims but redu
AimThe aim was to explore the ambulance service as experienced by present and former employees.BackgroundOver the last decade, the number of ambulance assignments has increased annually by about 10%, and as many as 50% of all ambulance assignments are considered non-urgent. This raises questions about which assignments the Ambulance Service (AS) is supposed to deal with.Design/methodData were coll
Viktor Yushchenko’s 2010 designation of Stepan Bandera, the war‐time leader of the most radical and violent branch of the Ukrainian far right, as a national hero constituted, in many ways, the climax of the third post‐Soviet Ukrainian president’s instrumentalization of history. Yushchenko’s political use of history triggered sharply polarized, and often emotional discussions of Bandera’s role in h
Endospore cortex peptidoglycan synthesis is notrequired for bacterial growth but essential for endo-spore heat resistance. It therefore constitutes anamenable system for research on peptidoglycan bio-genesis. The Bacillus subtilis sporulation-specificclass B penicillin-binding protein (PBP) SpoVD andmany homologous PBPs contain two conserved cys-teine residues of unknown function in the transpepti
We are motivated by a tantalizing open question in exact algorithms: can we detect whether an n-vertex directed graph G has a Hamiltonian cycle in time significantly less than 2^n? We present new randomized algorithms that improve upon several previous works: 1. We show that for any constant 0
