(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
An angular analysis of the decay B0 d → K∗µ +µ − is presented, based on protonproton collision data recorded by the ATLAS experiment at the LHC. The study is using 20.3 fb−1 of integrated luminosity collected during 2012 ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
During the shutdown of the CERN Large Hadron Collider in 2013-2014, an additional pixel layer was installed between the existing Pixel detector of the ATLAS experiment and a new, smaller radius beam pipe. The motivation ...
