Substituting fields within the action: consistency issues and some applications
Josep M. Pons
In field theory, as well as in mechanics, the substitution of some fields in terms of other fields at the level of the action raises an issue of consistency with respect to the equ…
Revisiting the gauge principle: enforcing constants of motion as constraints
Petr Jizba, Josep Maria Pons
In this paper we examine an alternative formulation of the gauge principle in which the emphasis is shifted from the symmetry transformations to their generators. We show that the…
Notes on a SQCD-like plasma dual and holographic renormalization
A. L. Cotrone, J. M. Pons, P. Talavera
We study the thermodynamics and the jet quenching parameter of a black hole solution dual to a SQCD-like plasma which includes the backreaction of fundamental flavors. The free ene…
Dimensional reduction, truncations, constraints and the issue of consistency
Josep M. Pons
A brief overview of dimensional reductions for diffeomorphism invariant theories is given. The distinction between the physical idea of compactification and the mathematical proble…
Heavy hadron spectra from spin chains and strings
A. L. Cotrone, L. Martucci, J. M. Pons +1
We study the spectrum of hadronic states made up of very massive complex scalar fields in a confining gauge theory admitting a supergravity dual background. We show that for a sub-…
Fluctuations around classical solutions for gauge theories in Lagrangian and Hamiltonian approach
Olivera Miskovic, Josep M. Pons
We analyze the dynamics of gauge theories and constrained systems in general under small perturbations around a classical solution (background) in both Lagrangian and Hamiltonian f…
