Continuum description of profile scaling in nanostructure decay
Continuum description profile scaling nanostructure decay
2015/10/16
The relaxation of axisymmetric crystal surfaces with a single facet below the roughening transition is studied via a continuum approach that accounts for step energy g1 and step-step interaction energ...

Continuum Theory Nanostructure Decay Microscale Condition
2015/10/16
The morphological relaxation of faceted crystal surfaces is studied via a continuum approach. Our formulation includes (i) an evolution equation for the surface slope that describes step line tension,...

2014/12/23
The decay KL→π0e+e- is searched for as a signal of direct ΔS=1 CP violation. We provide a thorough updating of the analysis of the three components of the decay: (1) direct CP violation, (2) CP violat...

The weak decay model
2014/12/23
The weak nomesonic decay ofΛ-hypernuclei is studied in the context of a one-meson-exchange model. Predictions are made for the decay rate, thep/nstimulation ratio and the asymmetry in polarized hypern...
Final state interactions in the decay of heavy quarks
Secondary scattering B meson duality
2014/12/23
I discuss some recent results on the systematic behavior of final state rescattering which makes use of the limit of a heavy B meson. The results suggest that soft final state interactions do not disa...

2014/12/22
We examine the importance of JP=1/2+,1/2- resonances for weak nonleptonic Ω- decays within the framework of chiral perturbation theory. The spin-1/2 resonances are included into an effective theory an...

Decay of amplitude induced mixing pure state low energy
2014/12/20
The π0→γγ decay width is analyzed within the combined framework of chiral perturbation theory and the 1/Nc expansion up to O(p6) and O(p4×1/Nc) in the decay amplitude. The η′ is explicitly included in...
Kelvin-Wave Cascade and Decay of Superfluid Turbulence
Kelvin wave distortion vortex line cryogenic superfluid turbulence dynamics
2014/12/20
Kelvin waves (kelvons), the distortion waves on vortex lines, play a key part in the relaxation of superfluid turbulence at low temperatures. We present a weak-turbulence theory of kelvons. We show th...

2010/12/21
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...
