Higher dimensional black holes as constrained systems
J. A. Nieto, E. A. Leon, V. M. Villanueva
We construct a Lagrangian and Hamiltonian formulation for charged black holes in a d-dimensional maximally symmetric spherical space. By considering first new variables that give r…
String-inspired representations of photon/gluon amplitudes
Naser Ahmadiniaz, Christian Schubert, Victor M. Villanueva
The string-based Bern-Kosower rules provide an efficient way for obtaining parameter integral representations of the one-loop N - photon/gluon amplitudes involving a scalar, spinor…
Hamiltonian Noether theorem for gauge systems and two time physics
V. M. Villanueva, J. A. Nieto, L. Ruiz +1
The Noether theorem for Hamiltonian constrained systems is revisited. In particular, our review presents a novel method to show that the gauge transformations are generated by the…
Relativistic Top Deviation Equation and Gravitational Waves
J. A. Nieto, J. Saucedo, V. M. Villanueva
By using the relativistic top theory, we derive a relativistic top deviation equation. This equation turns out to be a generalization of the geodesic deviation equation for a pair…
Non-minimal coupling for spin 3/2 fields
Victor M. Villanueva, Juan A. Nieto, and Octavio Obregon
The problem of the electromagnetic coupling for spin 3/2 fields is discussed. Following supergravity and some recent works in the field of classical supersymmetric particles, we fi…
Quantisation without Gauge Fixing: Avoiding Gribov Ambiguities through the Physical Projector
Victor M. Villanueva, Jan Govaerts, Jose-Luis Lucio-Martinez
The quantisation of gauge invariant systems usually proceeds through some gauge fixing procedure of one type or another. Typically for most cases, such gauge fixings are plagued by…
