Surface Nuclear Magnetic Resonance (SNMR) - A new method for exploration of ground water and aquifer properties
surface NMR ground water aquifer assessment hydrogeophysics
font style='font-size:12px;'>
2015/9/29
The Surface Nuclear Magnetic Resonance (SNMR) method is a fairly new technique in geophysics to assess ground water, i.e. existence, amount and productibility by measurements at the surface. The NMR t...

Nuclear parity violation in effective field theory
Photovoltaic (pv) nuclear nuclear parameterized coupling
font style='font-size:12px;'>
2014/12/20
We reformulate the analysis of nuclear parity violation (PV) within the framework of effective field theory (EFT). To O(Q), the PV nucleon–nucleon (NN) interaction depends on five a priori unknown con...

2014/12/20
In the phenomenological description of the nuclear interaction an important role is traditionally played by the exchange of a scalar I=0 meson, the sigma, of mass 500–600 MeV, which however is not see...
Nuclear central force in the chiral limit
Chiral perturbation theory function quality component physical spectrum energy function
font style='font-size:12px;'>
2014/12/20
Chiral perturbation theory supplemented by the Omnes function is employed to study the strength of the isoscalar central nuclear interaction, GS, in the chiral limit vs the physical case. A very large...
Constraints on the variability of quark masses from nuclear binding
Nuclear binding the light quark heavy nuclei attractive

2014/12/19
Based on recent work on nuclear binding, we update and extend the anthropic constraints on the light quark masses, with results that are more tightly constrained than previously obtained. We find that...
