Optimization of Trial Wave Functions for Hamiltonian Lattice Models

Matteo Beccaria

We propose a new Monte Carlo algorithm for the numerical study of general lattice models in Hamiltonian form. The algorithm is based on an initial Ansatz for the ground state wave…

Bounds on universal new physics effects from fermion-antifermion production at LEP2

M. Beccaria, F. M. Renard, S. Spagnolo +1

We consider lepton-antilepton annihilation into a fermion-antifermion pair at variable c.m. energy. We propose for this process a simple parametrization of the virtual effects of t…
