High Precision for Hard Processes 2018
1. - 3. OKtober 2018
The Seventh International Workshop on High Precision for Hard Processes at the LHC (HP² 2018) will be held from 1-3 October 2018 at the Physics Institute of the University of Freiburg.
This series of workshops is devoted to high-precision studies of hard scattering processes at hadron colliders. The main themes of these workshops are recent developments and new results in theoretical computations in quantum field theory and their applications to collider phenomenology. These topics are particularly relevant as the LHC experiments at CERN are now entering a new phase of precision measurements.
Topics:
- Precise predictions for Standard Model and Beyond the Standard Model phenomenology
- New mathematical techniques for amplitude calculations
- Automated tools for multi-leg amplitudes
- Status reports and implications of current LHC results

11th International Workshop on Top Quark Physics (TOP 2018)
16. - 21. September 2018
The 11th International Workshop on Top Quark Physics (TOP 2018) in Bad Neuenahr is a platform that brings together experts who work in the field of experimental and theoretical top-quark physicists. A focus is placed on precision predictions for processes involving top quarks and on the most recent measurements. This involves in particular measurements from the LHC experiments ATLAS and CMS, but also from the Tevatron. Emphasis is also placed on searches for new physics with top quarks and the models that predict such processes. Furthermore, future projects will be discussed, e.g. prospects of top-quark physics at the HL-LHC or at a next-generation lepton collider.

Large Hadron Collider Physics (LHCP2018)
04. - 09. Juni 2018
The LHCP conference series started in 2013 after a successful fusion of two international conferences, "Physics at Large Hadron Collider Conference" and "Hadron Collider Physics Symposium". This year it takes place in Bologna, Italy. The conference program will be devoted to a detailed review of the latest experimental and theoretical results on collider physics, particularly the most recent results of the LHC Run II, and discussions on further research directions within the high energy particle physics community including both theory and experiment sides. The main goal of the conference is to provide intense and lively discussions between experimentalists and theorists in research areas such as the Standard Model Physics and Beyond, the Higgs Boson, Supersymmetry, Heavy Quark Physics and Heavy Ion Physics as well as the recent progress in the high luminosity upgrades of the LHC and future colliders developments.

- comparing existing methods and assessing their strengths and limitations;
- quantifying the analytical and numerical challenges for the application of the proposed methods to general multi-jet QCD processes at NNLO;
- preparing the ground for extensions of the method beyond NNLO;
- studying the implications of all-order information from amplitude-level factorisation theorems for the problem of subtraction at high-orders.

Naturalness, Hierarchy, and Fine Tuning
28. Februar - 2. März 2018
The workshop takes place here at TTK! The requirement of naturalness has long served as an influential constraint on model-building in theoretical particle physics. Yet there are many ways of understanding what, precisely, this requirement amounts to, from restrictions on the amount of fine-tuning that a model can exhibit, to prohibitions on sensitive dependence between physics at different scales, to the requirement that dimensionless parameters defining the Lagrangian of a theory all be of order one unless they are protected by a symmetry. This workshop aims to clarify the relationships among these concepts of naturalness and their connection to the hierarchy problem, as well as to assess arguments for and against imposing various forms of naturalness as a requirement on particle physics model-building.
