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.
Measurement of the gas-flow reduction factor of the KATRIN DPS2-F differential pumping section

Abstract: We determined the gas-flow reduction factor of the second forward Differential Pumping Section (DPS2-F) for the KATRIN experiment using a dedicated vacuum-measurement setup and by detailed m...
Transition probabilities and dynamic structure factor in the ASEP conditioned on strong flux
Transition probabilities dynamic structure factor strong flux
2010/11/23
We consider the asymmetric simple exclusion processes (ASEP) on a ring constrained to produce an atypically large flux, or an extreme activity. Using quantum free fermion techniques we find the time-d...
