Introduction to the Neoclassical Interpretation: Quantum Steampunk
In a previous paper we outlined a series of historical touchpoints between classical aether theories and modern theoretical physics which showed a shared conceptual lineage for the modern tools and methods of the most common interpretations and fluid based “Hydrodynamic” treatments of an electromagnetic medium. It was proposed that, though the weight of modern experimentation leaves an extremely narrow and convoluted window for even a reconceptualization of a medium, all of modern physics recognizes a plethora of behaviors and attributes for free space and these physics are interchangeable with modern methods for treating superfluid-like continuums. Thus the mathematical equivalence of the methods do not comprise alternative physics but an alternative interpretation of the same physics. Though many individual components describing a “neo-aether” or “quintessence” are available, an overarching structural outline of how these tools can work together to provide an alternative working overview of modern physics has remained undefined. This paper will propose a set of introductory concepts in the first outline of a toy model which will later connect the alternative tools and conceptualizations with their modern counterparts. This introductory paper provides the simpler “100-miles out” overview of the whole of physics from this perspective, in an easily comprehensible, familiar and intuitive, informal dialog fashion. While this paper grants the largest and loosest introductory overview, subsequent papers in this series will address the finite connections between modern physics and this hydrodynamic view
Relative outer automorphisms of free groups
Let be a system of free factors of . The group of relative
automorphisms is the group given by the automorphisms of

group of relative outer automorphisms is defined as , where is the normal subgroup of

virtual cohomological dimension of this group.Comment: 24 pages, 16 figures, corrected typos, revised argument in section 5,

Final-state interactions effects in neutral-current neutrino and antineutrino cross sections at MiniBooNE kinematics
The analysis of the recent neutral-current elastic neutrino and
antineutrino-nucleus scattering cross sections measured by the MiniBooNE
Collaboration requires relativistic theoretical descriptions also accounting
for the role of final-state interactions. In this work we investigate the
sensitivity to final-state interactions and compare the MiniBooNE data with the
results obtained in the relativistic Green's function model with different
parameterizations for the phenomenological relativistic optical potential.Comment: 4 pages, 3 figures. version published in Physical Review
The Relativistic Green's function model and charged-current inclusive neutrino-nucleus scattering at T2K kinematics
We compare the results of the relativistic Green's function model with the
experimental data of the charged-current inclusive differential
neutrino-nucleus cross sections published by the T2K Collaboration. The model,
which is able to describe both MINERA and MiniBooNE charged-current
quasielastic scattering data, underpredicts the inclusive T2K cross sections.Comment: 6 pages, 4 figures. arXiv admin note: text overlap with

The relativistic Green's function model in charged-current quasielastic neutrino and antineutrino scattering at MINERA kinematics
The analysis of charged-current quasielastic neutrino and
antineutrino-nucleus scattering cross sections requires relativistic
theoretical descriptions also accounting for the role of final-state
interactions. We compare the results of the relativistic Green's function model
with the data recently published by the MINERA Collaboration. The model is
able to describe both MINERA and MiniBooNE data.Comment: 6 pages, 3 figure
The Relativistic Green's Function Model for Quasielastic Neutrino-Nucleus Scattering
A model based on the relativistic impulse approximation for quasielastic
lepton-nucleus scattering is presented. The effects of the final-state
interactions (FSI) between the emitted nucleon and the residual nucleus are
described by the relativistic Green's function model where FSI are treated
consistently with the exclusive scattering and using the same complex optical
potential. The results of the model are compared with the results of different
descriptions of FSI and with available data for neutrino-nucleus scattering.Comment: 10 pages, 4 figures, contribution to IWNT-32, 23-29 June 2013, Rila

Neutral-current neutrino-nucleus quasielastic scattering
A relativistic distorted-wave impulse-approximation model to quasielastic
neutral-current neutrino-nucleus scattering is developed, using the
relativistic mean field theory for the bound state and taking into account the
final state interaction in the relativistic scattering state. Results for the
neutrino (antineutrino) reaction on 12C target nucleus are presented in an
energy range between 500 and 1000 MeV. The sensitivity to the strange quark
content of the axial-vector form factor is discussed.Comment: 12 pages, 9 figure
Neutrino-nucleus quasi-elastic scattering and strange quark effects
A relativistic distorted-wave impulse-approximation model is applied to
quasi-elastic neutrino-nucleus scattering. The bound state is obtained in the
framework of the relativistic mean field theory and the final state interaction
is taken into account in the scattering state. Results for the charged- and
neutral-current neutrino (antineutrino) reactions on C target nucleus
are presented and the sensitivity of various quantities to the strange quark
content of the nucleon weak current is discussed.Comment: 18 pages, 10 figure
