Beam Line Parameters for PERC at the ESS
Abstract Precision measurements of correlations in neutron beta decay test the standard model of particle physics. Here, pulsed neutron beams are invaluable to fight systematic effects. We show that the Proton Electron Radiation Channel PERC in...

Corrections of Prompt-neutron Emission in Fission-fragment Experiments
Abstract The number of emitted prompt neutrons in the fission process is strongly dependent on the fragment mass. The deformation of the fragments as well as shell effects give the characteristic “sawtooth” shape. It is well known that the total...

Born reciprocity in string theory and the nature of spacetime
Abstract After many years, the deep nature of spacetime in string theory remains an enigma. In this Letter we incorporate the concept of Born reciprocity in order to provide a new point of view on string theory in which spacetime is a derived...

Direct detection and solar capture of dark matter with momentum and velocity dependent elastic scattering
Abstract We explore the momentum and velocity dependent elastic scattering between the dark matter (DM) particles and the nuclei in detectors and the Sun. In terms of the non-relativistic effective theory, we phenomenologically discuss ten kinds of...

Enhanced production of neutron-rich rare isotopes in the reaction of 25 MeV/nucleon 86Kr on 64Ni
Abstract The cross sections and velocity distributions of projectile-like fragments from the reaction of 25 MeV/nucleon 86Kr+64Ni have been measured using the MARS recoil separator at Texas A&M, with special emphasis on the neutron rich...

Remarks on an experimental study of the formation and decay of the p̄He+ atomcule

Thermalization of quantum fields from time-reversal invariant evolution equations
Abstract We study the time evolution of correlation functions in closed quantum systems for nonequilibrium ensembles of initial conditions. For a scalar quantum field theory we show that generic time-reversal invariant evolutions approach...

KamLAND, terrestrial heat sources and neutrino oscillations
Abstract We comment on the first indication of geo-neutrino events from KamLAND and on the prospects for understanding Earth energetics. Practically all models of terrestrial heat production are consistent with data within the presently limited...

One-loop renormalizability of all 2-dimensional Poisson–Lie σ-models
Abstract We perform a systematic study of the one-loop renormalizability of all Poisson–Lie T-dualizable σ-models with two-dimensional targets. We show that whatever Drinfeld double and whatever matrix of coupling constants we consider the...

Universal singlets, supergravity and inflation
Abstract In supersymmetric theories, the occurrence of universal singlets is a delicate issue, because they usually induce tadpoles that destabilize the hierarchy. We study the effects of these tadpoles in supersymmetric hybrid inflation models. The ...

Identification of excited states in 140Dy
Abstract Excited structures in the proton-rich nucleus 140Dy have been established following the decay of an 8− isomer. The excitation energy of the isomer is established to be 2.16 MeV with a half-life of 7.3±1.5 μs. The isomer decays into the...

First-order radiative corrections to polarized muon decay spectrum
Abstract The first-order QED corrections to the polarized muon decay spectrum are considered. The exact dependence on electron and muon masses is kept. Numerical results are presented.

Testing a Fourier-accelerated hybrid Monte Carlo algorithm
Abstract We describe a Fourier-accelerated hybrid Monte Carlo algorithm suitable for dynamical fermion simulations of non-gauge models. We test the algorithm in supersymmetric quantum mechanics viewed as a one-dimensional Euclidean lattice field...

Noncommutative instantons on R2NC×R2C
Abstract We study U(1) and U(2) noncommutative instantons on R 2 NC×R 2 C based on the ADHM construction. It is shown that a mild singularity in the instanton...
