The influence of νh11/2 occupancy on the magnetic moments of collective 21+ states in A∼100 fission fragments
Abstract The magnetic moments of I π =21 + states in even–even A∼100 fission fragments have been measured using the Gammasphere array, using the technique of...

Accelerating Hilbert–Einstein universe without dynamic dark energy
Abstract By using an unmodified Einstein gravity theory it is shown that all of the speeding-up effects taking place in the current universe are entirely due to the quantum effects associated with the background radiation or to the combination of...

Anthropic estimates of the charge and mass of the proton
Abstract By combining a renormalization group argument relating the charge e and mass m p of the proton by ...

Limits on inelastic dark matter from ZEPLIN-III
Abstract We present limits on the WIMP–nucleon cross section for inelastic dark matter from a reanalysis of the 2008 run of ZEPLIN-III. Cuts, notably on scintillation pulse shape and scintillation-to-ionisation ratio, give a net exposure of ...

Quarkonium dissociation in the presence of a small momentum space anisotropy
Abstract We consider the dissociation of heavy quarkonium in a medium close to thermal equilibrium but with a small momentum space anisotropy. Dissociation is defined to take place when the width of the ground state equals its binding energy. We...

Variation of mass in primordial nucleosynthesis as a test of induced matter brane gravity
Abstract The variation of mass in induced matter theory using Ceroch–Stewart–Walter perturbations of submanifolds is redefined. It is shown that the deviation of primordial Helium production due to a variation on the difference between the “rest”...

Can the baryon number density and the cosmological constant be interrelated?
Abstract A toy model is proposed in which the cosmological constant and the baryon number density of the Universe are interrelated. The model combines the mechanism of Dimopoulos and Susskind [S. Dimopoulos, L. Susskind, Phys. Rev. D 18 (1978) 4500] ...

Evidence of a new state in 11Be observed in the 11Li β-decay
Abstract Coincidences between charged particles emitted in the β-decay of 11Li were observed using highly segmented detectors. The breakup channels involving three particles were studied in full kinematics allowing for the reconstruction of the...

Hawking radiation from a rotating acoustic black hole
Abstract Using the new global embedding approach and analytical continuation method of wave function we discuss Hawking radiation of acoustic black holes. Unruh–Hawking temperature of the acoustic black hole is derived. The corresponding relation...

The baryon anomaly: Evidence for color transparency and direct hadron production at RHIC
Abstract We show that the QCD color transparency of higher-twist contributions to inclusive hadroproduction cross sections, where baryons are produced directly in a short-distance subprocess, can explain several remarkable features of high- ...

An Algebra of Automata That Includes Both Classical and Quantum Entities
Abstract We describe an algebra for composing automata which includes both classical and quantum entities. We illustrate by describing in detail a quantum protocol.

Estimation of the variation in target strength of objects in the air
Abstract Target strength is one of the key values for sonar systems. The parameter is very useful in activities related to detection and estimation of marine organisms, object identification and sonar calibration. The essential difference between...

A new approach to prompt fission neutron TOF data treatment
Abstract The prompt neutron emission in spontaneous fission of 252Cf has been investigated applying digital signal electronics along with associated digital signal processing algorithms. A new mathematical approach, applicable to single events, was...

Monte Carlo Simulation of Prompt Fission Gamma Emission
Abstract Prompt fission gamma spectra and multiplicities are investigated through the Monte Carlo code FIFRELIN which has been developed recently [1]. Up to now, this code was mainly used to study the characteristics (spectrum and multiplicity) of...

Next decade of sterile neutrino studies
Abstract We review the status of sterile neutrino dark matter and discuss astrophysical and cosmological bounds on its properties as well as future prospects for its experimental searches. We argue that if sterile neutrinos are the dominant fraction ...
