Contributions of order to form factors and unitarity of the CKM matrix
N. H. Fuchs, M. Knecht, J. Stern
The form factors for the semileptonic decay are computed to order in generalized chiral perturbation theory. The main difference with the standard ex…
Direct Single Instanton Contributions to Finite Energy Sum Rules
A. S. Deakin, V. Elias, N. H. Fuchs +3
Instanton contributions to pseudoscalar finite-energy sum rules are extracted from the explicit single-instanton contribution to the pseudoscalar Laplace sum rule in the instanton…
Determination of Two-Loop Scattering Amplitude Parameters
M. Knecht, B. Moussallam, J. Stern +1
The chiral expansion of the amplitude to the order of two loops was expressed in terms of six independent parameters in a previous paper: four of these are shown here to satis…
The Low Energy Amplitude to One and Two Loops
M. Knecht, B. Moussallam, J. Stern +1
The low-energy amplitude is computed explicitly to two-loop accuracy in the chiral expansion. It depends only on six independent (combinations of) low-energy constants which a…
Markov chain analysis of random walks on disordered medium
Sonali Mukherjee, Hisao Nakanishi, Norman H. Fuchs
We study the dynamical exponents and for a particle diffusing in a disordered medium (modeled by a percolation cluster), from the regime of extreme disorder (i.e.,…
Light Quark Masses from Exclusive Tau Decays: An Experimental Proposal
J. Stern, N. H. Fuchs, M. Knecht
A method of indirect measurement of the light quark running mass is elaborated in detail. It is based on measuring 1\%-level azimuthal angular asymmetries…
