Measurements of underlying-event properties using neutral and charged particles in pp collisions at s√=900 GeV and s√=7 TeV with the ATLAS detector at the LHC
We present first measurements of charged and neutral particle-flow correlations in pp collisions using the ATLAS calorimeters. Data were collected in 2009 and 2010 at centre-of-mass energies of 900 GeV and 7 TeV. Events ...
Bodenmüdigkeit bei Rosen: Neue Forschungsansätze
Bodenmüdigkeit bei Rosen (Rosenmüdigkeit) ist ein schwerwiegendes Problem sowohl in Privatgärten als auch öffentlichen Parks sowie für den kommerziellen Rosenanbau. Im folgenden Artikel wird der Begriff Rosen müdigkeit ...
Photoluminescence of a single quantum emitter in a strongly inhomogeneous chemical environment.
We present the results of a comprehensive photoluminescence study of defect centres in single SiO2 nanoparticles. We show that the photo-physical properties of the luminescent centres strongly resemble those of single dye ...
High-resolution polarised Raman scattering study on spin-phonon coupling in multiferroic MnWO 4
MnWO4 passes three antiferromagnetic phase transitions below the Néel temperature TN=13.5 K. One of these phases is also ferroelectric andMnWO4 is therefore referred to as multiferroic.We investigated the effect of ...
A Practical One-Pot Synthesis of Positron Emission Tomography (PET) Tracers via Nickel-Mediated Radiofluorination.
Recently a novel method for the preparation of (18)F-labeled arenes via oxidative [(18)F]fluorination of easily accessible and sufficiently stable nickel complexes with [(18)F]fluoride under exceptionally mild reaction ...
A study of the material in the ATLAS inner detector using secondary hadronic interactions
The ATLAS inner detector is used to reconstruct secondary vertices due to hadronic interactions of primary collision products, so probing the location and amount of material in the inner region of ATLAS. Data collected ...
Measurement of the jet fragmentation function and transverse profile in proton–proton collisions at a center-of-mass energy of 7 TeV with the ATLAS detector
The jet fragmentation function and transverse profile for jets with 25 GeV<p T jet<500 GeV and |η jet|<1.2 produced in proton–proton collisions with a center-of-mass energy of 7 TeV are presented. The measurement is performed ...
Search for a heavy neutral particle decaying into an electron and a muon using 1 fb−1 of ATLAS data
A search is presented for a high mass neutral particle that decays directly to the e ± μ ∓ final state. The data sample was recorded by the ATLAS detector in s√=7~TeV pp collisions at the LHC from March to June 2011 and ...
Search for top squarks in final states with one isolated lepton, jets, and missing transverse momentum in s√=13 TeV pp collisions with the ATLAS detector
The results of a search for the top squark, the supersymmetric partner of the top quark, in final states with one isolated electron or muon, jets, and missing transverse momentum are reported. The search uses the 2015 ...
A starfish bed in the Middle Miocene Grand Bay Formation of Carriacou, The Grenadines (West Indies)
The first starfish bed to be recognized from the Antilles is a lensoid body in the middle Miocene Grand Bay Formation of Carriacou, The Grenadines (West Indies). This unit was deposited in a turbidite basin in a region ...
