Περίληψη:
A study of the channel e(+)e(-) –> mu(+)mu(-)gamma ISR, where gamma ISR
is an initial state radiation photon, is presented using data collected
by the DELPHI experiment from 1991 to 1994. The total cross-section at
effective annihilation: energies (root s’) below the Z(0) peak is
obtained by using the events with relatively hard initial state
radiative photon(s) (E gamma > 1 GeV). The differential cross-section as
a function of the muon polar production angle is also determined in
order eo extract the forward-backward asymmetries for the reaction
e(+)e(-) –> mu(+)mu(-) at energies root s’ between 20 and 87 GeV. The
ratio of the helicity cross-sections sigma LL+sigma RR/sigma RL+sigma
LR, where the two subscripts stand for the helicities of the incoming
e(-) and outgoing mu(-) respectively, is extracted from the differential
cross-sections in order to test the Standard Model and to look for new
physics near 80 GeV. No deviations from the Standard Model were found.
