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...
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 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...
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...
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...
