Searches for pair-production of supersymmetric particles under the assumption of non-conservation of R-parity with a dominant LL (E) over bar or (U) over bar(D) over bar(D) over bar term have been performed using the data collected by the DELPHI experiment at LEP in e(+)e(-) collisions at centre-of-mass energies from 192 up to 208 GeV. No excess of data above Standard Model expectations was observ
An updated search is performed for gluino, top squark, or bottom squark R-hadrons that have come to rest within the ATLAS calorimeter, and decay at some later time to hadronic jets and a neutralino, using 5.0 and 22.9 fb(-1) of pp collisions at 7 and 8 TeV, respectively. Candidate decay events are triggered in selected empty bunch crossings of the LHC in order to remove pp collision backgrounds. S
We report a search for Higgs bosons that are produced via vector boson fusion and subsequently decay into invisible particles. The experimental signature is an energetic jet pair with invariant mass of O(1)TeV and O(100)GeV missing transverse momentum. The analysis uses 36.1 fb−1 of pp collision data at s=13TeV recorded by the ATLAS detector at the LHC. In the signal region the 2252 observed event
New metastable massive particles with electric and colour charge are features of many theories beyond the Standard Model. A search is performed for long-lived gluino-based R-hadrons with the ATLAS detector at the LHC using a data sample corresponding to an integrated luminosity of 31 pb(-1). We search for evidence of particles that have come to rest in the ATLAS detector and decay at some later ti
The ATLAS detector at the Large Hadron Collider is used to search for excited electrons and excited muons in the channel pp -> ll* -> ll gamma, assuming that excited leptons are produced via contact interactions. The analysis is based on 13 fb(-1) of pp collisions at a centre-of-mass energy of 8 TeV. No evidence for excited leptons is found, and a limit is set at the 95% credibility level on the c
A search for single top-quark production via flavour-changing neutral current processes from gluon plus up- or charm-quark initial states in proton-proton collisions at the LHC is presented. Data collected with the ATLAS detector in 2012 at a centre-of-mass energy of 8 TeV and corresponding to an integrated luminosity of 20.3 fb[Formula: see text] are used. Candidate events for a top quark decayin
The European Union is one of the world’s most impactful development actors. As such, it has adopted the Policy Coherence for Development framework in order to minimize contradictions between policies that affect developing countries. The ultimate goal of the framework is to increase development effectiveness to the welfare of developing partners. However, the existing literature is rich in doubts
Det finns idag robotar som är särskilt anpassade för att användas av räddningsteam i följderna av katastrofer som hjälpmedel i deras arbete att lokalisera och rädda människor instängda i trånga utrymmen. De är dock mycket dyra vilket begränsar deras användande och gör att användarna tvekar innan de skickar in en robot med risken att skada eller förlora den. Detta projekt dokumenterar det första stRobots currently exist that are specifically designed for use in the wake of disasters to help rescue teams in their work of locating and rescuing individuals trapped in confined spaces. However, they are prohibitively expensive which limits their adoption and causes the operators to think twice before they're deploying a robot with the risk of losing or damaging it. This project details the f
Numerous past studies investigating the performance of hedge funds suffer from two distinct problems: unreliable and biased return data inherent in virtually all databases and the use of static asset-pricing models. Using “indexes of indexes” for our hedge fund returns, both free of biases and highly representative, we investigate which risk factors investors are exposed to and whether hedge fund
A search for the dimuon decay of the Standard Model (SM) Higgs boson is performed using data corresponding to an integrated luminosity of 139 fb−1 collected with the ATLAS detector in Run 2 pp collisions at s=13 TeV at the Large Hadron Collider. The observed (expected) significance over the background-only hypothesis for a Higgs boson with a mass of 125.09 GeV is 2.0σ (1.7σ). The observed upper li
In 2023, the first edition of the diachronic-contemporary Swedish AcademyDictionary (SAOB) was finished after more than 130 years of work. The dictionary contains over 500,000 entries and describes the Swedish language from the 1520s to the present day. However, a consequence of the extended time of publication is that a significant part of the content, in particular in the first volumes, was out In 2023, the first edition of the diachronic-contemporary Swedish Academy Dictionary (SAOB) was finished after more than 130 years of work.

The ALICE Collaboration reports a search for jet quenching effects in high-multiplicity (HM) proton-proton collisions at s = 13 TeV, using the semi-inclusive azimuthal-difference distribution ∆φ of charged-particle jets recoiling from a high transverse momentum (high-pT,trig) trigger hadron. Jet quenching may broaden the ∆φ distribution measured in HM events compared to that in minimum bias (MB) e
A search for forward proton scattering in association with light-by-light scattering mediated by an axion-like particle is presented, using the ATLAS Forward Proton spectrometer to detect scattered protons and the central ATLAS detector to detect pairs of outgoing photons. Proton-proton collision data recorded in 2017 at a centre-of-mass energy of s = 13 TeV were analysed, corresponding to an inte
We study, from an experimental point of view, the main ways to detect standard high mass Higgs bosons (from 300 Gev up to about 1 TeV) when they decay into W- and Z- pairs at the SSC. We also consider the corresponding W- and Z”-pair continuum which may itself provide interesting physics, and we pay some attention to the case of an intermediate mass charged Higgs decaying into rvr, (met =300 GeV).
Searches for dijet resonances with sub-TeV masses using the ATLAS detector at the Large Hadron Collider can be statistically limited by the bandwidth available to inclusive single-jet triggers, whose data-collection rates at low transverse momentum are much lower than the rate from standard model multijet production. This Letter describes a new search for dijet resonances where this limitation is
We critically assess mainstream accounting and finance research applying methods from computational linguistics (CL) to study financial discourse. We also review common themes and innovations in the literature and assess the incremental contributions of work applying CL methods over manual content analysis. Key conclusions emerging from our analysis are:(a) accounting and finance research is behin
A direct search for lepton-flavour-violating H -> mu tau decays of the recently discovered Higgs boson with the ATLAS detector at the LHC is presented. The analysis is performed in the H -> mu tau(had) channel, where tau(had) is a hadronically decaying tau-lepton. The search is based on the data sample of proton-proton collisions collected by the ATLAS experiment corresponding to an integrated lum
A search for heavy Majorana neutrinos in events containing a pair of high-p(T) leptons of the same charge and high-p(T) jets is presented. The search uses 20.3 fb(-1) of pp collision data collected with the ATLAS detector at the CERN Large Hadron Collider with a centre-of-mass energy of root s = 8TeV. The data are found to be consistent with the background-only hypothesis based on the Standard Mod
A search for the decays of the Higgs and Z bosons to J/psi gamma and Upsilon(nS)gamma (n = 1,2,3) is performed with pp collision data samples corresponding to integrated luminosities of up to 20.3 fb(-1) collected at root s = 8 TeV with the ATLAS detector at the CERN Large Hadron Collider. No significant excess of events is observed above expected backgrounds and 95% C.L. upper limits are placed o
In this essay I argue that with too few alternative approaches, the strong feminist epistemological habit of attending to the political utility of art risks placing representations of subjective narratives whose emancipatory qualities might be unclear or doubtful out of scholarly reach. Feminist art historian Irit Rogoff discusses how feminist art historians are inclined to acknowledge visual repr
