Publikováno v: Nuclear Data Sheets. 118:437-441

The 237Np neutron-induced fission cross section has been recently measured in a large energy range (from eV to GeV) at the n_TOF facility at CERN. When compared to previous measurements the n_TOF fission cross section appears to be higher by 5–7% b

The U-238 fission cross section is an international standard beyond 2 MeV where the fission plateau starts. However, due to its importance in fission reactors, this cross-section should be very accurately known also in the threshold region below 2 Me

Noncommutative Geometry and the Physics of the LHC Era

Autor: Christoph A. Stephan

Publikováno v: Quantum Mathematical Physics ISBN: 9783319269009

Noncommutative geometry allows to unify the basic building blocks of particle physics, Yang-Mills-Higgs theory and general relativity, into a single geometrical framework. The resulting effective theory constrains the couplings of the standard model

The Spectral Action for Dirac Operators with Skew-Symmetric Torsion

Autor: Christoph A. Stephan, Frank Pfäffle, Florian Hanisch

Publikováno v: Communications in Mathematical Physics. 300:877-888

We derive a formula for the gravitational part of the spectral action for Dirac operators on 4-dimensional manifolds with totally anti-symmetric torsion. We find that the torsion becomes dynamical and couples to the traceless part of the Riemann curv

We will present a new extension of the standard model of particle physics in its almostcommutative formulation. This extension has as its basis the algebra of the standard model with four summands [11], and enlarges only the particle content by an ar
