Production of Secondaries in High Energy Heavy Ion Collisions
J. Dias de Deus, Yu. M. Shabelski
In the framework of Quark-Gluon String Model we calculate the inclusive spectra of secondaries produced in heavy ion collisions at intermediate (CERN SPS) and at much higher (RHIC)…
Brane Lorentz Symmetry from Lorentz Breaking in the Bulk
O. Bertolami, C. Carvalho
We propose the mechanism of spontaneous symmetry breaking of a bulk vector field as a way to generate the selection of bulk dimensions invisible to the standard model confined to t…
Generating multi-GeV electron bunches using single stage laser wakefield acceleration in a 3D nonlinear regime
W. Lu, M. Tzoufras, C. Joshi +5
The extraordinary ability of space-charge waves in plasmas to accelerate charged particles at gradients that are orders of magnitude greater than in current accelerators has been w…
Deformation quantization of noncommutative quantum mechanics and dissipation
C. Bastos, O. Bertolami, N. C. Dias +1
We review the main features of the Weyl-Wigner formulation of noncommutative quantum mechanics. In particular, we present a -product and a Moyal bracket suitable for this th…
Yukawa Textures, New Physics and Nondecoupling
Gustavo C. Branco, M. N. Rebelo, J. I. Silva-Marcos
We point out that New Physics can play an important r\^ ole in rescuing some of the Yukawa texture zero ans\" atze which would otherwise be eliminated by the recent, more precise m…
Charged shells in Lovelock gravity: Hamiltonian treatment and physical implications
Goncalo A. S. Dias, Sijie Gao, Jose' P. S. Lemos
Using a Hamiltonian treatment, charged thin shells in spherically symmetric spacetimes in d dimensional Lovelock-Maxwell theory are studied. The coefficients of the theory are chos…
