Low energy inflation models fermion
2014/12/23
In theories in which the parameters of the low energy theory are not unique, perhaps having different values in different domains of the universe as is possible in some inflationary models, the fermio...
Anthropic considerations in multiple-domain theories and the scale of electroweak symmetry breaking
The standard model quality parameters quantum physical parameter values
2014/12/22
One of the puzzles of the Standard Model is why the mass parameter which determines the scale of the Weak interactions is closer to the scale of Quantum Chromodymanics (QCD) than to the Grand Unificat...
Fine tunings and quark masses: Phenomenology of multiple domain theories
Particles physical parameters the universe
2014/12/22
This talk describes some of the consequences for particle phenomenology of the hypothesis that the physical parameters may vary in different domains of the universe.
Generalized polarizabilities of the nucleon in chiral effective theories
Generalized polarizability nuclear detecting electron scattering chiral perturbation theory
2014/12/22
Using the techniques of chiral effective field theories we evaluate the so called “generalized polarizabilities,” which characterize the structure dependent components in virtual Compton scattering of...

A Comment on the Letter by J. Hove, S. Mo, and A. Sudbø Phys. Rev. Lett. 85, 2368 (2000). The authors of the Letter offer a Reply.
When Effective Field Theories Fail
Effective field theory the meson circulation perturbation theory reggie physics
2014/12/19
In this talk, I describe and defend four non-standard claims about four effective field theories, and try to extract some lessons about the limits of effective field theory. The four theses (and a cap...
Spontaneously Broken Erlangen Program Offers a Bridge Between the Einstein and the Yang-Mills Theories
gravitation Erlangen Program Yang-Mills Einstein
2012/5/31
We shall give dynamics to our spacetime manifold by first identifying the local affine symmetry as the characterizing symmetry for our geometry \'a la Felix Klein, and then by prescribing 16 gauge vec...
Does Lorentz Force Law Contradict the Principle and Theories of Relativity for Uniform Linear Motion?
Lorentz Force Law Principle and Theories of Relativity Uniform Linear Motion Classical Physics
2012/5/29
I show that no force or torque is generated in cases involving a charge and a magnet with their relative velocity zero, in any inertial frame of reference. A recent suspicion of an anomalous torque an...
Dimension of the moduli space and Hamiltonian analysis of BF field theories
Index theorem moduli space Hamiltonian dynamics
2011/9/22
Abstract: By using the Atiyah-Singer theorem through some similarities with the instanton and the anti-instanton moduli spaces, the dimension of the moduli space for two and four-dimensional BF theori...
A pure Dirac's canonical analysis for four-dimensional BF theories
pure Dirac's canonical analysis four-dimensional BF theories Mathematical Physics
2011/9/19
Abstract: We perform Dirac's canonical analysis for a four-dimensional $BF$ and for a generalized four-dimensional $BF$ theory depending on a connection valued in the Lie algebra of SO(3,1). This anal...
Supersymmetric K field theories and defect structures
supersymmetric K field theories defect structures High Energy Physics - Theory
2011/10/9
Abstract: We construct supersymmetric K field theories (i.e., theories with a non-standard kinetic term) in 1+1 and 2+1 dimensions such that the bosonic sector just consists of a nonstandard kinetic t...
Hamiltonian study for Chern-Simons and Pontryagin theories
Hamiltonian study Chern-Simons Pontryagin theories Mathematical Physics
2011/9/15
Abstract: The Hamiltonian analysis for the Chern-Simons theory and Pontryagin invariant, which depends of a connection valued in the Lie algebra of SO(3,1), is performed. By applying a pure Dirac's me...
One-loop Renormalized Coefficient of Noncommutative Supersymmetric Yang-Mills-Chern-Simons Gauge Theories in Three Dimensions
One-loop Renormalized Coefficient Noncommutative Supersymmetric Yang-Mills-Chern-Simons Gauge Theories
2011/7/28
Abstract: Recent studies of the $AdS_4/CFT_3$ correspondence involve the construction of a peculiar supersymmetric gauge theory on the worldvolume of multiple M2s branes as a boundary field theory. Un...
Homotopical Poisson reduction of gauge theories
Homotopical Poisson reduction gauge theories Algebraic Geometry
2011/7/26
Abstract: The classical Poisson reduction of a given Lagrangian system with (local) gauge symmetries has to be done before its quantization. We propose here a coordinate free and self-contained mathem...

2011/7/26
Abstract: It is shown that when in a higher order variational principle one fixes fields at the boundary leaving the field derivatives unconstrained, then the variational principle (in particular the ...
