The Helmholtz International Summer School (HISS) entitled “Quantum Field Theory at the Limits:from Strong Fields to Heavy Quarks (SF→HQ)”, was held in the period July 18-30, 2016 at the Bo-goliubov Laboratory of Theoretical Physics (BLTP) of the Joint Institute for Nuclear Research (JINR)in Dubna, Russia, as part of the activities of the Dubna International Advanced School of Theoreti-cal Physics (DIAS-TH). It was co-organized by Ahmed Ali (DESY Hamburg), David Blaschke (JINRDubna, MEPhI & Univ. Wroclaw), Holger Gies (HI Jena), and Mikhail Ivanov (JINR Dubna), and wasattended by 82 participants (faculty + students), not counting the JINR physicists who attended somelectures as non-registered participants. The school (SF→HQ) continued the workshops and schools ofthe HISS series held earlier in Dubna (1993, 1996, 2000, 2005, 2008, 2013), Bad Honnef (1994) andRostock (1997). The scientific program of the school consisted of five regular (one-hour long) lecturesin the morning and afternoon sessions, with typically two contributed talks given by younger partic-ipants (students and postdocs), each half-hour long, in the late afternoons. Altogether, we had sixtylectures by the faculty and participants. In addition, black-board exercises were held in the post-lunchperiods on selected aspects of strong fields and field theory.
