摘要：
The pion form factor is calculated using quenched twisted mass QCD with beta = 6.0 and maximal twisting angle omega = +/- pi/2. Two pion masses and several values of momentum transfer are considered. The momentum averaging procedure of Frezzotti and Rossi is used to reduce lattice spacing errors, and numerical results are consistent with the expected O(a) improvement.
