Asymptotic limits and the structure of the pion form factor
Dispersion technology solve meson chiral perturbation theory high energy low energy limit
2014/12/22
We use dispersive techniques to address the behavior of the pion form factor as Q2 → ∞ and Q2 → 0. We perform the matching with the constraints of perturbative QCD and chiral perturbation theory in th...
Factorization in graviton scattering and the "natural" value of the g factor
Graviton scattering amplitude gyromagnetic ratio independent of the rotation
2014/12/20
The factorization property of graviton scattering amplitudes is reviewed and show to be valid only if the "natural" value of the gyromagnetic ratio $g_S=2$ is employed -- independent of spin.

Brief remarks Electric dipole moment enhancement factor thallium
2012/2/28
In a recent paper by Porsev et al. [arXiv:1201.5615v1], the authors have claimed to have resolved the controversy arising from the different ab initio results available for the EDM enhancement factor ...
Current response, structure factor and hydrodynamic quantities of a two- and three-dimensional Fermi gas from the operator product expansion
Current response structure factor
2011/7/21
We apply the operator product expansion to determine the asymptotic form of the current response of a Fermi gas in two and three dimensions.
Technique for high axial shielding factor performance of large-scale, thin, open-ended, cylindrical Metglas magnetic shields

We present results on inclusive electrons for 1.5 $ < p_{\rm T} < $ 6 GeV/$c$ in {Pb-Pb} collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV measured with ALICE at the LHC and compare these to a cocktail of ...
A Simple Model to Measure Linewidth Enhancement Factor (α) for Multi-wavelengths Semiconductor Laser
Semiconductor laser, Fabry-Pérot laser, injection-locking
2011/9/2
A novel and simple model is proposed for the measurement of the linewidth enhancement factor (LEF) α of multiwavelengths semiconductor laser. It is based on the suppression characteristics of an arbit...
