The Electron Capture Decay of 163-Ho to Measure the Electron Neutrino Mass with sub-eV Accuracy and Beyond
electron neutrino mass electron capture decay 163Ho
2012/2/24
We have investigated the possibility of measuring the electron neutrino mass with sub-eV sensitivity by studying the electron capture decay of 163-Ho with cryogenic microcalorimeters. In this paper we...
Axino dark matter and baryon number asymmetry from Q-ball decay in gauge mediation
Axino dark matter baryon number asymmetry Q-ball decay gauge mediation
2012/2/21
We investigate the Q-ball decay into the axino dark matter in the gauge-mediated supersymmetry breaking. In our scenario, the Q ball decays mainly into nucleons and partially into axinos to account fo...
Solar Influence on Nuclear Decay Rates: Constraints from the MESSENGER Mission
stroparticle physics – nuclear reactions – Sun:particle emission
2011/10/12
We have analyzed Cs-137 decay data, obtained from a small sample onboard the MESSENGER spacecraft en route to Mercury, with the aim of setting limits on a possible correlation between nuclear decay ra...
Gravitino dark matter and baryon asymmetry from Q-ball decay in gauge mediation
Gravitino dark matter baryon asymmetry Q-ball decay gauge mediation
2011/10/18
We investigate the Q-ball decay in the gauge-mediated SUSY breaking. Q balls decay mainly into nucleons, and partially into gravitinos, while they are kinematically forbidden to decay into sparticles ...
A decay of the ultra-high-energy neutrino $\nu_e \to e^- W^+$ in a magnetic field and its influence on the shape of the neutrino spectrum
the ultra-high-energy neutrino the neutrino spectrum
2011/1/13
The width of the neutrino decay into the electron and $W$ boson in a strong external magnetic field is obtained from the imaginary part of the neutrino self-energy. This result corrects the formulae ...
On the rate of gravitational inflaton decay via gauge trace anomaly
gravitational inflaton decay gauge trace anomaly
2010/11/17
We analyze decay processes of the inflaton field, , during the coherent oscillation phase after inflation in f( )R gravity. It is inevitable that the inflaton decays grav-itationally into gauge field...
On the Implications of Late Internal Dissipation for Shallow-Decay Afterglow Emission and Associated High-Energy Gamma-Ray Signals
gamma-rays burst general— gamma rays theory— radiation mechanisms non-thermal
2010/11/10
The origin of the shallow-decay emission during early X-ray afterglows has been an open issue since the launch of the Swift satellite. One of the appealing models is the late internal dissipation mode...
Aims. We report on a detailed study of the optical afterglow of GRB 061121 with our original time-series photometric data. In conjunction with X-ray observations, we discuss the origin of its optical ...
Power Spectrum Analysis of Physikalisch-Technische Bundesanstalt Decay-Rate Data: Evidence for Solar Rotational Modulation
Solar and Stellar Astrophysics (astro-ph.SR) Nuclear Experiment (nucl-ex) Instrumentation and Detectors (physics.ins-det)
2010/12/29
Evidence for an anomalous annual periodicity in certain nuclear decay data has led to speculation concerning a possible solar influence on nuclear processes.
Evidence of Decay of Flux Ratio of Fe to Fe–Ni Line Features with Electron Temperature in Solar Flares
Sun flares corona—X-rays
2010/9/15
We report observational evidence of the decay of the flux ratio of Fe to Fe–Ni line features as a function of plasma electron temperature in solar flares in comparison to that theoretically predicted ...
A Method for Judging Decay or Growth of the Magnetic Field of Pulsar
Pulsar—decay or growth of magnetic field—method of judgement
2010/9/15
This paper provides a method for judging growth or decay of the magnetic field of pulsar by using pulse period P, or frequency ν, and its first and second derivatives P˙, P¨ or ν˙, ν¨. The author uses...
