Shape vibrations of topological fermions

Manfried Faber, Alexander Kobushkin, Mario Pitschmann

We analyze the model of topological fermions, where charged fermions are treated as topological solitons. We discuss vibrations of soliton shapes. It is shown that depending on the…

Perturbative nuclear physics

Silas R. Beane, David B. Kaplan, Aleksi Vuorinen

We present a new formulation of effective field theory for nucleon-nucleon (NN) interactions which treats pion interactions perturbatively, and we offer evidence that the expansion…

PDE-Foam - a probability-density estimation method using self-adapting phase-space binning

Dominik Dannheim, Tancredi Carli, Karl-Johan Grahn +2

Probability Density Estimation (PDE) is a multivariate discrimination technique based on sampling signal and background densities defined by event samples from data or Monte-Carlo…

Probing Electron Correlation via Attosecond XUV Pulses in the Two-Photon Double Ionization of Helium

J. Feist, S. Nagele, R. Pazourek +4

Recent experimental developments of high-intensity, short-pulse XUV light sources are enhancing our ability to study electron-electron correlations. We perform time-dependent calcu…

The point spread function of electrons in a magnetic field, and the decay of the free neutron

D. Dubbers, L. Raffelt, B. Maerkisch +2

Experiments in nuclear and particle physics often use magnetic fields to guide charged reaction products to a detector. Due to their gyration in the guide field, the particles hit…
