Invariants of Spin Networks Embedded in Three-Manifolds
João Faria Martins, Aleksandar Mikovic
We study the invariants of spin networks embedded in a three-dimensional manifold which are based on the path integral for SU(2) BF-Theory. These invariants appear naturally in Loo…
J/psi and psi' production and their normal nuclear absorption in proton-nucleus collisions at 400 GeV
NA50 Collaboration
We report a new measurement of J/psi, psi' and Drell-Yan cross-sections, in the kinematical domain and , performed at the CERN-SP…
Electron Trapping by Electric Field Reversals in Glow Discharges
Mario J. Pinheiro
The phenomena of electric field reversal in glow discharges is discussed. Several models are described and the link between the electric field reversal, electron's trapping and the…
Predictions of an A_4 model with a five-parameter neutrino mass matrix
L. Lavoura, H. Kuhbock
We consider a model with an A_4 flavour symmetry, recently proposed by E. Ma, and make a numerical study, through scatter plots, of its neutrino mass matrix.
Regularization of odd-dimensional AdS gravity: Kounterterms
Rodrigo Olea
As an alternative to the Dirichlet counterterms prescription, I introduce the concept of Kounterterms as the boundary terms with explicit dependence on the extrinsic curvature K_{i…
On Yetter's Invariant and an Extension of the Dijkgraaf-Witten Invariant to Categorical Groups
João Faria Martins, Timothy Porter
We give an interpretation of Yetter's Invariant of manifolds in terms of the homotopy type of the function space , where is a crossed module and is its…
On the Homotopy Type and the Fundamental Crossed Complex of the Skeletal Filtration of a CW-Complex
João Faria Martins
We prove that if is a CW-complex, then the homotopy type of the skeletal filtration of does not depend on the cell decomposition of up to wedge products with -disks…
Charged-fermion masses in SO(10): analysis with scalars in 10+120
L. Lavoura, H. Kuhbock, W. Grimus
We consider the scenario in which the mass matrices of the charged fermions in the SO(10) Grand Unified Theory are generated exclusively by renormalizable Yukawa couplings to one $…
