n 2004 it has been shown that scattering amplitudes can be expressed by
glueing together simple three-point on-shell amplitudes. These so-called
BCFW-recursion relations can for instance be used to proof the explicit
form of the n-gluon scattering amplitude as conjectured by Parke and
Taylor. Moreover, the basic building blocks, the three-point on-shell
amplitudes, are, apart from a...
Using unconventional SUSY, we construct a model that allow us to obtain a theory that is chiral and contains dynamical gravity, therefore resembling the structure of the Standard Model and General Relativity. We review the main features of Zanelli's unconventional SUSY that allow us to couple matter fields in a gauge invariant way. We will discuss the difficulties, advantages and future tasks...
In this talk we will present first numerical calculation of the Odderon intercept and slope obtained with IR-regulator approach.
Momentum space topology (MST) has been used since a long time in the study of condensed matter physics and nowadays it has become the main theoretical tool for the description and classification of topological insulators. This is because within MST it is possible to construct a topological invariant quantity in terms of two-point Greens function,...
Feynman integrals (FIs) play a central role in quantum field theory (QFT). They comprise the coefficients of weak-coupling expansions within theoretical particle physics, allowing for high-precision comparisons of theory with collider experiments with the ultimate goal of discovering new elementary particles.
Given this strong phenomenological motivation, FIs form interesting objects to...
Weyl semimetals (WSMs) are a new class of topological materials that exhibit a bulk Hall effect and a chiral magnetic effect. The topological contribution of these unusual electromagnetic responses can be characterized
by an axion term $\theta \mathbf{E} \cdot \mathbf{B}$ with space and time dependent axion angle $\theta(r,t)$. In this presentation I will show the electromagnetic fields...
