Hadron Collider School - HASCO 2012 The main objectives of the hadron collider physics school (HASCO) were introductory topics in  elementary particle physics, in particular in hadron collider physics as relevant for research at the  Large Hadron Collider (LHC). This included lectures and tutorials on theoretical foundations of the  Standard Model of elementary particle physics as well as experimental techniques to test it.  Furthermore, a focus was placed on statistical data analysis and an introduction to the software  package ROOT. In addition, students did have the opportunity to discuss state of the art  measurements and results with senior scientists in the field.  The target group were Bachelor, Master and early PhD students, i.e. mainly beginners in the field. The  main activities were lectures, tutorials, and student seminars. These were complemented by  excursions, and sport activities. The learning outcome was better and more compatible theoretical knowledge of the fundamentals of  elementary particle physics, but more importantly als hands-on experience with widely used software  tools, statistics data analysis and experimental measurement techniques. The expected outputs were  software programs, group presentations, and short summary reports. The academic achievements  were be credited with ECTS points.  The school did take place at the Georg-August-Universtät Göttingen from 15. - 27. July 2012.  This ERASMUS intensive program is supported by the European Union under the contract DE-2011-ERA/MOBIP-1-29759-3-52
