The gravitational constant as a quantum mechanical expression
Abstract A quantitatively verifiable expression for the gravitational constant is derived in terms of quantum mechanical quantities. This derivation appears to be possible by selecting a suitable physical process in which the transformation of the...

Raising sfermion masses by adding extra matter fields
Abstract The renormalization group flow of soft supersymmetry breaking masses is sensitive to the field contents of the theory one considers. We point out that the addition of extra vector-like matter fields to the minimal supersymmetric standard...

CP test in J/ψ→γφφ decay
Abstract We propose to test CP symmetry in the decay J/ψ→γφφ, for which large data sample exists at BESII, and a data sample of 1010 J/ψ's will be collected with BESIII and CLEO-C program. We suggest some CP asymmetries in this ...

Fine tuned vortices in lattice SU(2) gluodynamics
Abstract We report measurements of the action associated with center vortices in SU(2) pure lattice gauge theory. In the lattice units the excess of the action on the plaquettes belonging to the vortex is approximately a constant, independent on the ...

Observation of a dramatic hindrance of the nuclear decay of isomeric states for fully ionized atoms
Abstract The half-lives of isomeric states of fully ionized 144Tb, 149Dy and 151Er have been measured. These nuclides were produced via fragmentation of about 900 MeV/u 209Bi projectiles, separated in flight with the fragment separator (FRS) and...

Comments on the evolution of strongly degenerate neutrinos in the early universe
Abstract We reconsider the evolution of strongly degenerate neutrinos in the early universe. Our chief concern is the validity of the entropy conservation after the neutrino annihilation process has frozen out (so that the establishment of chemical...

Novel Ways of Heat Removal from Highly Irradiated Superconducting Windings in Accelerator Magnets
Abstract Novel ideas of heat removal from superconducting windings in accelerator type magnets are investigated with the help of a recently developed and validated thermal model of a magnet cold mass implemented in COMSOL Multiphysics. Here the...

Direct sensitivity computation for 1D hydrodynamic modelling vs classical empirical and Monte Carlo approaches
Abstract A finite volume method with a modified HLLC Riemann solver is proposed for the direct, equation-based, sensitivity solution of one-dimensional hyperbolic systems of conservation laws with discontinuous solutions. In the scope of...

Can the universe be represented by a superposition of spacetime manifolds?
Abstract In this article it is argued, that the universe cannot be modeled as a space-time manifold. A theorem of geometry provides that null geodesics on a space-time manifold which begin at the same point with the same initial tangent vector are...

Transition Matrices and Time Travel
Abstract It has been proven by Lee [1] that the grandfather paradox and Deutsch's unproven paradox are precluded for twoand three-state graphical models. We prove that both paradoxes are also precluded for a general n-state model. In addition, we...

Neutron Moderator Development Research at the Low Energy Neutron Source
Abstract The Low Energy Neutron Source at Indiana University completed its construction phase roughly three years ago, and one of the more active research thrusts at the facility since that time has been our attempts to advance the state of the art...

Simulation calculations of transmissions for neutron total cross-section measurements of MAs and LLFPs by complementary use of a compact accelerator-driven neutron source
Abstract We performed simulation calculations of neutron transmission spectra for minor actinide and long-lived fission product samples with pulsed neutron beams produced by the two neutron sources: the Accurate Neutron-Nucleus Reaction measurement...
