The workshop "Current Topics in Fundamental Physics" on the 16th of August will bring together experts from theoretical particle physics, cosmology and mathematics to discuss the latest developments at the interface of these three research areas.
Martín Lagares won the Best Poster Award at the ICTP Workshop on Scattering Amplitudes and Cosmology in Trieste. His poster shows some properties of scattering amplitudes in the framework of a useful toy-model theory. Martín visited our group in 2022 and will join us again this summer.
Today the workshop on Scattering Amplitudes and Cosmology starts. It takes place at the International Centre for Theoretical Physics (ICTP) in Trieste from April 17 to April 21. Nima Arkani-Hamed, Institute for Advanced Study (IAS), Princeton, USA, Johannes Henn, Max Planck Institute for Physics, Munich, Germany, and Jaroslav Trnka, University of California, Davis, USA, organize the event to bring together experts from scattering amplitudes, mathematics, and cosmology.
„Why is the sky dark at night?“ Paolo Benincasa, senior scientist in scattering amplitudes and cosmology, took the path to the answer together with high school students and walked with them through the mysteries of the universe.
Julian Miczajka brings physics to unconventional places. He talked about his research at a theater project for young students as well as at a workshop for Philosophy. Facts and figures are only a small part of his outreach activities. Julian enjoys getting into conversations with people and telling the stories that happen in physics – on the way to the fascinating questions about the nature of Nature. In our interview he tells us about playful outreach while using a toy model, and takes us step by step through the world of physics.
Nick Early works in two research fields at a time, in physics and in math. He already chose this two-fold path early in his career: While working on his PhD in mathematics he discovered new connections to theoretical physics and became fascinated by them. Today he translates fundamental processes, like scattering amplitudes, into mathematics to get a deeper understanding about them.
Prof. Nima Arkani-Hamed, theoretical physicist from the Institute for Advanced Study (IAS), Princeton, and Prof. Armin Nassehi, sociologist from LMU München, give answers to this question – and a glimpse into the future of science. Join our event in the main building („Senatssaal“) of the LMU München on July 18th and find out what happens when fundamental physics meets social science. The event is hosted by Dr. Jeanne Rubner, Vice President Global Communication TUM.
The principal investigator of our group, Johannes Henn, spent some time in Brussels at the center of European Research Policy. Here he tells us how he got there, whom he met, what he learned, and how he brings these experiences together in his daily work.
Théo Ferry and Francesco Calisto started an internship in our group. They are students from Paris and from Turin and will spend four months with us. Both of them work on independent projects in scattering amplitudes calculations and set steps to future research. To give an insight into their internships Francesco and Théo tell us some more about their projects – and their motivations.
Paolo Benincasa and William Torres Bobadilla give us a "Video-Q&A" about their common work. Together they search for what happened during the early stage of the universe.
The workshop „Virtual QCD Meets Gravity 2021“ takes place from December 13 – 17, via Zoom. The Mani L. Bhaumik Institute for Theoretical Physics at the UCLA invites researchers interested in the double-copy construction. This is the correspondence between Yang-Mills theory, one of the most important quantum field theories, and gravity. Be aware: The lecture times are local to Los Angeles :)
What can we learn about quantum chromodynamics (QCD) and collider physics from the research in supersymmetric toy models of Yang-Mills theory? This is discussed by Johannes Henn in a recent article published in the Annual Review of Nuclear and Particle Science.
The paper „Cluster Algebras for Feynman Integrals“ written by Dmitry Chicherin, Johannes Henn and Georgios Papathanasiou was honored with a Best Paper Award from the Cluster of Excellence Quantum Universe. Georgios Papathanasiou received the award for the outstanding scientific publication on September 14th.
A couple of weeks ago, Kai Yan gave one of four series of lectures at the “SAGEX PhD School in Amplitudes”. The School preceded the AMPLITUDES 2021 conference, which is one of the most important events for researchers in this field. Here she describes her research for us and talks about the importance of energy – for scattering processes and for discovering your own path.
Today AMPLITUDES 2021 starts. The newest results from the joint work of our Research Team Lead Johannes Henn, Nima Arkani-Hamed and Jaroslav Trnka will be presented on August 16, 8 pm (CEST).
Alex, one of our group members, recently published two papers with new results which provide valuable insight into the inner workings of quantum field theories. Talking about his newest findings we decided to also offer an insight into how he got to these findings – an unpretentious and honest journey into the whirls and hurdles of theoretical particle physics research and how to overcome them.
Do you want to know where nature starts becoming weird? And how scientists manage to explain it? Then watch this video about the Standard Model.
Recently Dmitry Chicherin, Johannes M. Henn and Georgios Papathanasiou published a paper on cluster algebra structures that have a high benefit for the research on scattering amplitudes. In the following article the authors go further than the recent results. They explain what cluster algebras are and how mathematical detective work revealed those hidden structure gems – to lighten up the way of theoretical processes.
Workshop and Symposium come together: From 17th to 21st May the RADCOR & LoopFest 2021 will take place in a fully virtual format. The conference is dedicated to the application of quantum field theory techniques to particle physics phenomenology.
Congratulations to our partner Thomas Gehrmann from the University of Zurich for winning an ERC Advanced Grant. His research on “Theory of particle collider processes at ultimate precision“ will receive funding for the next five years.
Dr. William J. Torres Bobadilla published together with other scientists from different institutions a Review in the European Journal of Physics C (EPJC). This review is an outcome of the workshop "Paving the way to alternative NNLO strategies".
Matt von Hippel works on Scattering Amplitudes and blogs about them. His goal: He wants to demystify scientific research and the people who do it.
Theoretical particle physicists are always on the search for new paths to answers about elementary particles. „In one of our latest research work we followed a new mathematical way, the cluster algebras“, says Johannes Henn, the leader of the research team at Scattering Amplitudes. He and his colleagues found promising results for the calculations of particle collisions.
Antonela Matijasic started her PhD in our research group at the beginning of this year. Here she tells you about her way to theoretical particle physics and how the search for a good challenge keeps her motivated. Thank you, Antonela!
Scattering amplitudes experts watch out: The Center for Quantum Mathematics and Physics (QMAP) at the University of California offers a series of virtual workshops called „Geomplitudes“. The second workshop will take place on February 8-9, 2021.
The theoretical physicist's answer: a precisely imagined world
Our group member Vasily Sotnikov speaks about theoretical particle physics in general and his latest research results in particular.
The SAGEX Marie Skłodowska-Curie ITN is organizing a school devoted to applications of Mathematica and Maple to the area of quantum scattering amplitudes within theoretical physics. Yang Zhang, one of our collaboration partners, will give a lecture series on: Introduction to Algebraic Geometry.
This question is set and also answered by the Quanta Magazine in one of their series. Please scroll down the article and you’ll find a paragraph about a camp of researchers called „amplitudeologists“.
Our new team member William J. Torres Bobadilla will give a talk on „Causal representation and Numerical Evaluation of Scattering Amplitudes“ on Friday, November 13th, 11:00 AM. If you want to join the seminar please email us for the zoom link.
Like any other science theoretical particle physics has its own language and its own terms. Even if some of these terms seem to be the same as in everyday life they have slightly other meanings in science. What can we do about this?
