Topological Levinson's theorem in presence of embedded thresholds and discontinuities of the scattering matrix
V. Austen, D. Parra, A. Rennie +1
A family of discrete Schroedinger operators is investigated through scattering theory. The continuous spectrum of these operators exhibit changes of multiplicity, and some of these…
Levinson's theorem for two-dimensional scattering systems: it was a surprise, it is now topological!
A. Alexander, D. T. Nguyen, A. Rennie +1
We prove a general Levinson's theorem for Schrödinger operators in two dimensions with threshold obstructions at zero energy. Our results confirm and simplify earlier seminal resul…
Determination of the parton distribution functions of the proton using diverse ATLAS data from collisions at , 8 and 13 TeV
ATLAS Collaboration
This paper presents an analysis at next-to-next-to-leading order in the theory of quantum chromodynamics for the determination of a new set of proton parton distribution functions…
A search for an unexpected asymmetry in the production of and pairs in proton-proton collisions recorded by the ATLAS detector at TeV
ATLAS Collaboration
This search, a type not previously performed at ATLAS, uses a comparison of the production cross sections for and pairs to constrain physics processes beyond th…
Measurements of sensor radiation damage in the ATLAS inner detector using leakage currents
ATLAS Collaboration
Non-ionizing energy loss causes bulk damage to the silicon sensors of the ATLAS pixel and strip detectors. This damage has important implications for data-taking operations, charge…
Search for dark matter in association with an energetic photon in pp collisions at = 13 TeV with the ATLAS detector
ATLAS Collaboration
A search for dark matter is conducted in final states containing a photon and missing transverse momentum in protonproton collisions at = 13 TeV. The data, collected…
