The cross sections and forward-backward asymmetries of hadronic and leptonic events produced in e(+)e(-) collisions at centre-of-mass energies from 130 to 183 GeV are presented. Results for e+e-: mu(+)mu(-), tau(+)tau(-), q (q) over bar, b (b) over bar and c (c) over bar production show no significant deviation from the Standard Model predictions. This enables constraints to be set upon physics beyond the Standard Model such as four-fermion contact interactions. leptoquarks, Z' bosons and R-parity violating squarks and sneutrinos. Limits on the energy scale Lambda of e(+)e(-) f (f) over bar contact interactions are typically in the range from 2 to 10 TeV. Limits on R-parity violating sneutrinos reach masses of a few hundred GeV/c(2) for large values of their Yukawa couplings.

Abstract
The cross sections and forward-backward asymmetries of hadronic and leptonic events produced in e(+)e(-) collisions at centre-of-mass energies from 130 to 183 GeV are presented. Results for e+e-: mu(+)mu(-), tau(+)tau(-), q (q) over bar, b (b) over bar and c (c) over bar production show no significant deviation from the Standard Model predictions. This enables constraints to be set upon physics beyond the Standard Model such as four-fermion contact interactions. leptoquarks, Z' bosons and R-parity violating squarks and sneutrinos. Limits on the energy scale Lambda of e(+)e(-) f (f) over bar contact interactions are typically in the range from 2 to 10 TeV. Limits on R-parity violating sneutrinos reach masses of a few hundred GeV/c(2) for large values of their Yukawa couplings.
