    Recently it has become apparent that there is a close connection between two modern descriptions of scattering amplitudes, the CHY formalism and the framework of positive geometries. This connection is facilitated by calculatingpushforwards through the scattering equations. To further investigate this remarkable connection, we develop tools to calculate these pushforwards without the need to...

  4. 2. On amplitude soft bootstrap methods
    Karol Kampf
    14/07/2022, 10:30

    Abstract: We know that infrared dynamics is connected with symmetry. We usually assume that the symmetry is considered primary and the corresponding properties as soft theorems are only secondary. I will demonstrate how fruitful can be the opposite perspective. A brief discussion on the classification of "interesting" theories using the so-called soft bootstrap methods will be given. It...

    Prof. Nima Arkani-Hamed, world-renowned theoretical physicist from the Institute for Advanced Study (IAS), Princeton, and Prof. Armin Nassehi, famous sociologist from LMU München, give answers to this question – and a glimpse into the future of science. First Arkani-Hamed will give an insight into the evolution of fundamental physics by presenting „The end of space-time“. Nassehi will then...

  10. 7. Antipodal Duality in Action at Eight Loops
    Lance Dixon
    20/07/2022, 10:30

    I describe a new duality which relates the MHV 6-point scattering amplitude to the 3-point form factor of the chiral stress tensor operator in planar N=4 super-Yang-Mills theory. A bizarre aspect of the duality is its reversal of the order of letters in the symbol (the antipode map). The duality also features a kinematic map from the parity-invariant slice of 6-point kinematics to full form...

  11. 8. Vector Spaces of Generalized Euler Integrals
    Anna-Laura Sattelberger
    21/07/2022, 10:30

    We study vector spaces associated to a family of generalized Euler integrals, as which also Feynman integrals can be understood. Those vector spaces have been investigated using tools from homological algebra and the theory of D-modules. The methods are ranging from Bernstein-Sato operators to de Rham cohomology up to hypergeometric systems. Based on ongoing work with Daniele Agostini, Claudia...
