Maximum norm a posteriori error estimation for parabolic problems using elliptic reconstructions
No full textA semilinear second-order parabolic equation is considered in a regular and a singularly perturbed regime. For this equation, we give computable a posteriori error estimates in the maximum norm. Semidiscrete and fully discrete versions of the backward Euler, Crank--Nicolson, and discontinuous Galerkin methods are addressed. For their full discretizations, we employ elliptic reconstructions that are, respectively, piecewise-constant, piecewise-linear, and piecewise-quadratic for in time. We also use certain bounds for the Green's function of the parabolic operator
Maximum-norm error analysis of a non-monotone FEM for a singularly perturbed reaction-diffusion problem
No full textLogical Terminology in the Epistles to the Hebrews
No full textIt is usually recognized that the author of the Epistle to the Hebrews is presenting an argument for the superiority of Christianity to the religion of the Old Covenant and that he bases this argument on the comparison of the Son of God with the angels and with Moses, on the comparison of the new high priest with the priests of old, and on the comparison of the sanctuary and the sacrifice of the New Covenant with those of the Old. It is furthermore agreed that he uses means of rhetoric to get his point across. Thus Michel says: In the letter to the Hebrews we have before us the first sermon whose author knew and imported into Christianity all the techniques of ancient rhetoric and all its speech forms. However, I have not been able to find a detailed analysis of these rhetorical means and style forms or an investigation of the author\u27s reasoning in detail. This article is intended to show several style forms used by the author and to describe their purpose in the context of the epistle
Search for t t ¯ H / A → t t ¯ t t ¯ production in the multilepton final state in proton–proton collisions at s = 13 TeV with the ATLAS detector
No full textAbstract A search for a new heavy scalar or pseudo-scalar Higgs boson (H/A) produced in association with a pair of top quarks, with the Higgs boson decaying into a pair of top quarks (H/A → t t ¯ ) is reported. The search targets a final state with exactly two leptons with same-sign electric charges or at least three leptons. The analysed dataset corresponds to an integrated luminosity of 139 fb −1 of proton–proton collisions collected at a centre-of-mass energy of 13 TeV with the ATLAS detector at the LHC. Two multivariate classifiers are used to separate the signal from the background. No significant excess of events over the Standard Model expectation is observed. The results are interpreted in the context of a type-II two-Higgs-doublet model. The observed (expected) upper limits at 95% confidence level on the t t ¯ H / A production cross-section times the branching ratio of H/A → t t ¯ range between 14 (10) fb and 6 (5) fb for a heavy Higgs boson with mass between 400 GeV and 1000 GeV, respectively. Assuming that only one particle, either the scalar H or the pseudo-scalar A, contributes to the t t ¯ t t ¯ final state, values of tan β below 1.2 or 0.5 are excluded for a mass of 400 GeV or 1000 GeV, respectively. These exclusion ranges increase to tan β below 1.6 or 0.6 when both particles are considered
Inclusive and differential cross-sections for dilepton t t ¯ production measured in s = 13 TeV pp collisions with the ATLAS detector
No full textAbstract Differential and double-differential distributions of kinematic variables of leptons from decays of top-quark pairs ( t t ¯ ) are measured using the full LHC Run 2 data sample collected with the ATLAS detector. The data were collected at a pp collision energy of s = 13 TeV and correspond to an integrated luminosity of 140 fb −1. The measurements use events containing an oppositely charged eμ pair and b-tagged jets. The results are compared with predictions from several Monte Carlo generators. While no prediction is found to be consistent with all distributions, a better agreement with measurements of the lepton p T distributions is obtained by reweighting the t t ¯ sample so as to reproduce the top-quark p T distribution from an NNLO calculation. The inclusive top-quark pair production cross-section is measured as well, both in a fiducial region and in the full phase-space. The total inclusive cross-section is found to be σ t t ¯ = 829 ± 1 stat ± 13 syst ± 8 lumi ± 2 beam pb , where the uncertainties are due to statistics, systematic effects, the integrated luminosity and the beam energy. This is in excellent agreement with the theoretical expectation
Test of the universality of and lepton couplings in -boson decays from events with the ATLAS detector
No full textThe Standard Model of particle physics encapsulates our current best
understanding of physics at the smallest scales. A fundamental axiom of this
theory is the universality of the couplings of the different generations of
leptons to the electroweak gauge bosons. The measurement of the ratio of the
rate of decay of bosons to -leptons and muons, , constitutes an important test of this
axiom. A measurement of this quantity with a novel technique using di-leptonic
events is presented based on 139 fb of data recorded with
the ATLAS detector in proton--proton collisions at TeV. Muons
originating from bosons and those originating from an intermediate
-lepton are distinguished using the lifetime of the -lepton,
through the muon transverse impact parameter, and differences in the muon
transverse momentum spectra. The value of is found to be and is in agreement with the
hypothesis of universal lepton couplings as postulated in the Standard Model.
This is the most precise measurement of this ratio, and the only such
measurement from the Large Hadron Collider, to date.Comment: 33 pages in total, author list starting page 17, 4 figures, 2 tables,

A balanced finite-element method for an axisymmetrically loaded thin shell
No full textsummary:We analyse a finite-element discretisation of a differential equation describing an axisymmetrically loaded thin shell. The problem is singularly perturbed when the thickness of the shell becomes small. We prove robust convergence of the method in a balanced norm that captures the layers present in the solution. Numerical results confirm our findings
