Abstract

The network of MPX detectors installed in ATLAS has successfully taken data from 2008 to 2013. The slope measurements for the long‐term time‐stability for both, the hit and heavy blob (thermal neutron) analyses, are below 1%. The relative uncertainty on the luminosity measurement is below 0.3% for one minute time intervals, where the value is set by the method to derive it. After the discovery of a Higgs boson the measurements of its properties are now at the forefront of research. The measurement of the associated production of a Higgs boson and a pair of top quarks is of particular importance as the ttH Yukawa coupling is large and thus a probe for physics beyond the Standard Model.
