Extended Supersymmetric sigma-Model Based on the SO(2N+1) Lie Algebra of the Fermion Operators
Seiya Nishiyama, Joao da Providencia, Constanca Providencia +1
Extended supersymmetric sigma-model is given, standing on the SO(2N+1) Lie algebra of fermion operators composed of annihilation-creation operators and pair operators. Canonical tr…
Operation of a Thick Gas Electron Multiplier (THGEM) in Ar, Xe and Ar-Xe
R. Alon, J. Miyamoto, M. Cortesi +8
We present the results of our recent studies of a Thick Gaseous Electron Multiplier (THGEM)-based detector, operated in Ar, Xe and Ar:Xe (95:5) at various gas pressures. Avalanche-…
Dynamical instabilities in density-dependent hadronic relativistic models
A. M. Santos, L. Brito, C. Providência
Unstable modes in asymmetric nuclear matter (ANM) at subsaturation densities are studied in the framework of relativistic mean-field density-dependent hadron models. The size of th…
Study of ATLAS sensitivity to FCNC top decays
J. Carvalho, N. Castro, L. Chikovani +6
The ATLAS experiment sensitivity to top quark Flavour Changing Neutral Current (FCNC) decays was studied at LHC using ttbar events. While one of the top quarks is expected to follo…
A Note on 3-quasi-Sasakian Geometry
Beniamino Cappelletti Montano, Antonio De Nicola, Giulia Dileo
3-quasi-Sasakian manifolds were recently studied by the authors as a suitable setting unifying 3-Sasakian and 3-cosymplectic geometries. In this paper some geometric properties of…
Additional Boundary Condition for a Wire Medium Connected to a Metallic Surface
Mario G. Silveirinha, Carlos A. Fernandes, Jorge R. Costa
In this work, we demonstrate that the interaction of electromagnetic waves with a microstructured material formed by metallic wires connected to a metallic surface can be described…
