Tests of Power Corrections to Event Shape Distributions from e+e- Annihilation
P. A. Movilla Fernández, O. Biebel, S. Bethke
A study of differential event shape distributions using e+e- data at centre-of-mass energies of 35 to 183 GeV is presented. We investigated non-perturbative power corrections for t…

Measurement of C-Parameter and Determinations of alpha_s from C-Parameter and Jet Broadening at PETRA Energies
P. A. Movilla Fernández, O. Biebel, S. Bethke +1
e^+e^- annihilation data recorded by the JADE detector at PETRA were used to measure the C-parameter for the first time at sqrt{s}= 35 and 44 GeV. The distributions were compared t…

Polarized Wannier functions: ab-initio study of the dielectric properties of silicon and gallium arsenide
Pablo Fernández, Andrea Dal Corso, Alfonso Baldereschi
We present a first-principles calculation of the electronic properties of crystalline silicon and gallium arsenide in a uniform electric field. Polarized Wannier-like functions whi…
