Electromagnetic corrections to light hadron masses
Electromagnetic corrections hadron masses
2011/1/7
At the precision reached in current lattice QCD calculations, electromagnetic effects are becoming numerically relevant. We will present preliminary results for electromagnetic corrections to light ha...
Renormalization of heavy-light currents in moving NRQCD
Renormalization of heavy-light currents moving NRQCD
2011/1/13
Heavy-light decays such as B → πℓν, B → K∗γ and B → K(∗)ℓℓ can be used to constrain the
parameters of the Standard Model and in indirect searches for new physics. While ...
The current-current correlator method has been used successfully to obtain very accurate results for quark masses and the coupling as. The calculations were done using Highly Improved Staggered Quarks...
The Electromagnetic Properties of the Light Pseudoscalar Mesons via the Primakoff Effect
The Electromagnetic Properties the Light Pseudoscalar Mesons the Primakoff Effect
2010/10/25
The PrimEx (Primakoff Experiment) Collaboration is currently preparing to perform a high precision (1.4%) measurement of the two photon decay width of the neutral pion, ¡¼o!°°. The propos...
Frame Dependence of the Pair Contribution to the Pion Electromagnetic Form Factor in a Light-Front Approach
Frame Dependence the Pair Contribution the Pion Electromagnetic Form Factor a Light-Front Approach
2010/10/28
The frame dependence of the pair-term contribution to the electromagnetic form factor of the pion is studied within the Light Front approach. A symmetric ansatz for the pion Bethe-Salpeter amplitude w...
Kinetics of Light-induced Metastable Defect Creation and Annealing in a-Si:H
a-Si:H Staebler-Wronski effect Light induced metastable defect CPM Photoconductivity Distribution of annealing activation energies
2010/4/13
Constant Photocurrent Method (CPM) and steady state photoconductivity measurements are used to investigate the creation of light-induced metastable defects in a-Si:H at room temperature and their anne...
