High Precision for Hard Processes 2018

October 1 to 3 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.


  • 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

1st Workshop on High Energy Theory and Gender

September 26 to 28 2018

This workshop at CERN will both focus on recent developments in theoretical high energy physics and cosmology, and discuss issues of gender and equal opportunities in the field.

In addition to talks on nuclear and string theory, SM and BSM phenomenology, lattice field theory and cosmology, each day talks and panel discussions will be dedicated to research on gender in academia, with an aim to further the development and implementation of action plans to support women and other minorities in physics.

11th International Workshop on Top Quark Physics (TOP 2018)

September 16 to 21 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)

June 4 to 9 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.

Subtracting Infrared Singularities Beyond NLO

April 10 to 13 2018

The goal of the workshop at the Higgs Centre for Theoretical Physics at Edinburgh is to bring together the leading experts in the field, in particular the proponents of existing methods at NNLO, with the goal of

  • 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

February 28 to March 2 2018

The workshop takes place here at TTK. It centers on dark matter searches at the LHC, but will also discuss other types of "invisible" particles, in particular long-lived particles, as well as non-LHC experiments (low-energy colliders, fixed-target experiments, complementary dark matter searches). Registration is now open!

The workshop is organised and funded by the "New Physics at the LHC" network of the German Research Foundation DFG.
