The design of a low energy (4 GeV) Neutrino Factory is described, along with its expected performance. The Neutrino Factory uses a high energy proton beam to produce charged pions. The  decay to produce muons (), which are collected, accelerated, and stored in a ring with long straight sections. Muons decaying in the straight sections produce neutrino beams. The scheme is based on previous de...

We study the scattering of two Skyrmions at low energy and large separation. We use the method proposed by Manton for truncating the degrees of freedom of the system from in nite to a manageable nite number. This corresponds to identifying the manifold consisting of the union of the low energy critical points of the potential along with the gradient ow curves joining these together and by posit...

We relate leptogenesis in a class of theories to low-energy experimental observables: quark and lepton masses and mixings. With reasonable assumptions motivated by grand unification, one can show that the CP-asymmetry parameter takes a universal form. Furthermore the dilution mass is related to the light neutrino masses. Overall, these models offer a natural explanation for a lepton asymmetry i...

A numerical method for solving Schrödinger’s equation based upon a Baker-CampbellHausdorff (BCH) expansion of the time evolution operator is presented herein. The technique manifestly preserves wavefunction norm, and it can be applied to problems in any number of spatial dimensions. We also identify a particular dimensionless ratio of potential to kinetic energies as a key coupling constant. Th...

Different interaction models treating hadronic collisions below Elab<100 GeV in air shower simulations are compared within the frame of the CORSIKA program. Their behaviour is studied in isolated collisions of protons or pions with light-mass targets in comparison with experimental data. It is discussed how model properties influence air-shower parameters like the longitudinal profile or the la...

In fiscal year 1981, Congress appropriated $1.85 billion for home heating assistance to help low-income households meet rapidly rising energy costs. Eligibility for payments was based on income and energy-cost criteria. This procedure represented a departure from the earlier Federal focus of assisting households facing emergency hardships. Funds for the Low-Income Energy Assistance Program were...

In supersymmetric models, the CP asymmetry produced in the decay of the lightest right-handed neutrino, ≡ ǫ, can be written as a function of weak scale parameters. We introduce a way of separating ǫ into contributions from the various weak-scale phases, and study the contribution of potentially measurable neutrino phases to leptogenesis. We find that the Majorana phase φ′, which could have obse...

Some issues regarding low energy neutrinos are reviewed. We focus on three aspects i)We show that by employing very low energy (a few keV) electron neutrinos, neutrino disappearance oscillations can be investigated by detecting recoiling electrons with low threshold spherical gaseous TPC’s. In such an experiment, which is sensitive to the small mixing angle θ13, the novel feature is that the os...
