Analysis of Experiments Exhibiting Time-Varying Nuclear Decay Rates: Systematic Effects or New Physics?
Exhibiting Time-Varying Nuclear Decay Rates Systematic Effects
2011/7/20
Since the 1930s, and with very few exceptions, it has been assumed that the process of radioactive decay is a random process, unaffected by the environment in which the decaying nucleus resides. There...
Evidence of theta(13)>0 from global neutrino data analysis
global neutrino data High Energy Physics
2011/7/22
The neutrino mixing angle theta(13) is at the focus of current neutrino research. From a global analysis of the available oscillation data in a 3-neutrino framework, we previously reported [Phys. Rev....
Phenomenological analysis of angular correlations in 7 TeV proton-proton collisions from the CMS experiment
Phenomenological analysis angular correlations proton-proton collisions CMS
2011/7/21
A phenomenological analysis is presented of recent two-particle angular correlation data on relative pseudorapidity ($\eta$) and azimuth reported by the Compact Muon Solenoid (CMS) Collaboration for $...
Derivation and quantitative analysis of the differential self-interrogation Feynman-alpha method
Derivation quantitative analysis differential self-interrogation Feynman-alpha
2011/7/20
A stochastic theory for a branching process in a neutron population with two energy levels is used to assess the applicability of the differential self-interrogation Feynman-alpha method by numericall...
Bayesian Analysis of $C_{x'}$ and $C_{z'}$ Double Polarizations in Kaon Photoproduction
Bayesian Analysis Double Polarizations Kaon Photoproduction
2010/12/29
Have been analyzed the latest experimental data for $\gamma + p \to K^{+} + \Lambda$ reaction of $C_{x'}$ and $C_{z'}$ double polarizations. In theoretical calculation, all of these observables can be...

Gamma Radiation Measurement System Marine Sediment Rock Analysis
2010/11/16
A new high-efficiency and low-background system for the measurement of natural gamma radioactivity in marine sediment and rock cores retrieved from beneath the seabed was designed, built, and install...
Analysis of three-nucleon forces effects in the $A=3$ system
Analysis of three-nucleon forces effects $A=3$ system
2011/1/6
Using modern nucleon-nucleon interactions in the description of the A = 3, 4 nuclear systems the 2 per datum results to be much bigger than one. In particular it is not possible to reproduce the thre...
One of the main challenges of the industry today is to face its impact on global warming considering that the greenhouse effect problem is not be solved completely yet. Magnetic refrigeration represen...
Multi-modal analysis for low energy neutron-induced fission of 235U
235U (n, f) multi-model prompt neutron fragment property
2009/12/24
Low energy neutron induced fission of 235U is studied in the framework of the multi-modal fission model. The fission fragment properties, such as the yields, the average total kinetic energy distribut...
