Semiclassical back reaction around a cosmic dislocation
V. A. De Lorenci, R. Klippert, E. S. Moreira
The energy-momentum vacuum average of a conformally coupled massless scalar field vibrating around a cosmic dislocation (a cosmic string with a dislocation along its axis) is taken…
Galactic foreground contribution to the BEAST CMB Anisotropy Maps
Jorge Mejía, Marco Bersanelli, Carlo Burigana +17
We report limits on the Galactic foreground emission contribution to the Background Emission Anisotropy Scanning Telescope (BEAST) Ka- and Q-band CMB anisotropy maps. We estimate t…
Relativistic free-particle quantization on the light-front: New aspects
J. H. O. Sales, A. T. Suzuki, G. E. R. Zambrano
We use the light-front machinery to study the behavior of a relativistic free particle and obtain the quantum commutation relations from the classical Poisson brackets. We argue th…
Quantum gauge boson propagators in the light front
A. T. Suzuki, J. H. O. Sales
Gauge fields in the light front are traditionally addressed via the employment of an algebraic condition in the Lagrangian density, where is the gauge field (Abe…
Surveillance on the light-front gauge fixing Lagrangians
Alfredo T. Suzuki, J. H. O. Sales
In this work we propose two Lagrange multipliers with distinct coefficients for the light-front gauge that leads to the complete (non-reduced) propagator. This is accomplished via…
