Fermion pair production in $e^+e^-$ collisions at high energy and limits on physics beyond the Standard Model

An update of high energy di-fermions measurements, together with Rc and asymmetries measurements in the b sector is presented for data taken from 189 to 207 GeV. Results show no significant deviation from SM predictions. These results combined with those at lower energies lead to more stringent cons...

description An update of high energy di-fermions measurements, together with Rc and asymmetries measurements in the b sector is presented for data taken from 189 to 207 GeV. Results show no significant deviation from SM predictions. These results combined with those at lower energies lead to more stringent constraints upon physics beyond the Standard Model such as leptoquarks.
