Delta-gravity and Dark Energy
J. Alfaro
We present a model of the gravitational field based on two symmetric tensors. The equations of motion of test particles are derived: Massive particles do not follow a geodesic but…
From isospin generators to BRST quantization of higher spin massless fields
J. Alfaro, M. Cambiaso
Motivated by construction of isospin generators in particle physics (built form the SU(2) algebra), we find an equivalence between the algebra of these generators and those of the…
Phenomenology of symmetry breaking from extra dimensions
J. Alfaro, A. Broncano, M. B. Gavela +2
Motivated by the electroweak hierarchy problem, we consider theories with two extra dimensions in which the four-dimensional scalar fields are components of gauge boson in full spa…
On the consistency of Lorentz invariance violation in QED induced by fermions in constant axial-vector background
J. Alfaro, A. A. Andrianov, M. Cambiaso +2
We show for the first time that the induced parity--even Lorentz invariance violation can be unambiguously calculated in the physically justified and minimally broken dimensional r…
Quantum gravity and spin 1/2 particles effective dynamics
J. Alfaro, H. A. Morales-Tecotl, L. F. Urrutia
Quantum gravity phenomenology opens up the possibility of probing Planck scale physics. Thus, by exploiting the generic properties that a semiclassical state of the compound system…
BRST Formulation of Partition Function Constraints
J. Alfaro, K. Bering, P. H. Damgaard
We show that constraints on the generating functional have direct BRST-extensions in terms of nilpotent operators that annihilate this generating functional, and which may be o…
