multi-loop-2007

The workshop on "Multi-loop Calculations: methods and applications" has been held at the Universite Pierre et Marie Curie from June 7 to June 8 2017. This workshop was the first of this kind in the Paris region as the subject matter is quite rarely dealt with in local workshops and conferences. The workshop offered the rather unique opportunity, even at the international level, to bring together both world-leading experts (physicists and mathematicians) in the developments of multi-loop techniques as well as scientists from various backgrounds (particle physics, mathematical physics, gauge theory, integrability, string theory, statistical mechanics, condensed matter physics,...) interested in the application of the techniques to specific problems. From the point of view of multi-loop techniques, a number of state-of-the art calculations were presented such as 5-loops in QCD, 6-loops in \( \Phi^4 \) in \(D=4-2\epsilon\) and even 7-loops in \(\Phi^4\) with the newly discovered method of graphical functions. Essential to these ground-breaking achievements are recent developments in computer algebra systems as well as in mathematics. New and different approaches to compute Feynman diagrams with the help of integrability techniques were also presented. Applications were covering a large spectrum: from elementary particle physics (collider physics within and beyond the Standard Model), to statistical mechanics and condensed matter physics (including applications to turbulence and to Dirac-Weyl materials), to quantum gravity. The dense 2-days workshop has been attended by approximately 50 participants including 18 speakers. It benefited from very good working conditions at the University Pierre et Marie Curie. In particular, amphi Charpak was very well suited to host the seminars and the conference reception in Zamansky tower 24th floor on the evening of June 7 offered to the participants a few hours to meet and discuss while enjoying a beautiful view on Paris.
