Abstract
We present measurements of the process at , where and are electrons or muons. Using of data from the D0 experiment, we observe 13 candidates with an expected background of events and measure a cross section . From the number of observed events and the boson transverse momentum distribution, we limit the trilinear gauge couplings to at the 95% C.L. for a form factor scale . Further, assuming that , we find at the 95% C.L. These are the most restrictive limits on the couplings available to date.
